Duofold’s history as a leader in winter apparel innovation
Duofold has been at the forefront of winter gear technology for over 145 years. Back in 1876, an American hosiery mill owner named John E. Fields recognized the need for unionsuits that could provide warmth and insulation for cold New England winters. His innovative two-piece design with a mock turtleneck and button-up drop seat was dubbed “Duofold” and quickly became popular with lumberjacks and other outdoor workers.
Fast forward to the 1930s when Duofold introduced the first thermal underwear made from two-ply yarns for superior insulation. They dubbed this game-changing fabric “Thermax”. Over the ensuing decades, Duofold continued improving their thermal base layers and by the 1950s were supplying US troops and expeditions with cold weather gear. Fun fact – Duofold base layers have been worn on Mount Everest since the very first summit in 1953!
In the 1980s, Duofold revolutionized base layers again by using a double-layer fabric sandwich with separate inner and outer layers. This allowed for combining insulation and moisture management in one garment. By the 1990s, they debuted the first dual-sided anti-microbial fabric treatment to reduce odor. Most recently, Duofold has pushed the envelope using high-tech synthetic fabrics and body mapping insulation zones.
Over a Century of Innovations
Throughout their long history, Duofold has introduced dozens of innovative fabrics, material blends, production methods, and garment designs. Some key innovations include:

Benefits of Duofold’s patented two-layer system for warmth
One of Duofold’s most important innovations that revolutionized base layers was introducing separate inner and outer layers. This patented two-layer system combines the key functions of insulation and moisture management into a single, integrated garment. By separating the roles of trapping heat versus wicking moisture, both functions can be optimized.
The Warmth is in the Balance
Duofold’s lightweight inner thermal layer acts like the insulation in your attic, trapping your body’s natural warmth and forming a cozy barrier from the cold outside. The close-fitting stretch fabric hugs the skin and efficiently reflects heat back to the core. You get that warm furnace feel that helps maintain a comfortable internal temperature.
Meanwhile, the outer moisture management layer draws sweat and dampness away from your skin where it can evaporate into the air. This critical second role keeps you dryer by dispersing the build-up of perspiration. By balancing insulation and moisture control, comfort in the cold is drastically elevated.
Two Layers Do The Job Far Better Than One
Early base layers tried to accomplish both insulation and moisture management in a single piece of fabric. However, the properties needed for those contrasting functions tend to counteract each other. Materials that are highly breathable to vent sweat sacrifice insulative ability. Fabrics designed for warmth do not effectively disperse moisture.
With their patented two-layer system, Duofold solved this conundrum by dividing the tasks. The result is base layer sets that truly excel at both trapping body heat and wicking away sweat. Two dedicated layers working together simply outperform single layers trying to do both.
Optimized for Aerobic or Static Activities
Duofold leverages the capabilities of their dual-layer system in different ways depending on the intended activity. For highly aerobic winter pursuits like Nordic skiing or snowshoeing, their Varitherm line prioritizes moisture management to prevent overheating and sogginess.
For more static activities like ice fishing or hunting, their heavyweight Expedition layers focus more heavily on insulation to retain warmth while sitting for long periods. Regardless of use case, dividing the work between two specialized layers optimizes overall comfort and performance.
Mimicking Technical Outdoor Apparel
Duofold’s two-layer approach mirrors the layered functionality of technical outerwear systems. Windproof hard shells layer over insulating mid layers to balance protection versus breathability. Fleece jackets add warmth under breathable rain jackets. The beauty of layering apparel is tuning the balance between competing needs.
Duofold base layers essentially integrate this approach right against your skin. Instead of needing as many external layers, the foundation provided by Duofold sets the stage for comfort and warmth by handling the first critical layers of moisture management and insulation.
Keeping You Warmer with Fewer Layers
Speaking of reducing external layers, Duofold’s two-layer system means you can wear less bulky outerwear while still staying just as warm. When the base layer itself handles insulation and moisture control, you won’t overheat and sweat as much under all your outer gear.
Staying dryer results in greater warmth with fewer layers. By the time your shell goes on over your slim Duofold base layers, you are ahead of the game in balancing warmth, breathability and flexibility.
Over 145 Years of Innovating Warmth
Duofold’s two-layer thermal system represents the culmination of over a century constantly innovating and improving cold weather base layers. Their trailblazing work balancing insulation and moisture management led to key patents and revolutionized the entire category. Staying warm and dry just got a whole lot easier thanks to Duofold’s innovations.
Key features of the Expedition base layer for extreme cold
Duofold’s Expedition line represents the pinnacle of base layer innovation for protecting against the most extreme cold. Key features of the Expedition two-layer system include:
Midweight Insulation Where It Matters
The inner thermal layer uses a midweight insulation strategically mapped to critical warmth zones. The chest, abdomen, and upper back feature Thermax insulation sandwiched between soft thermal knits. This extra insulation protects the core organs where steady warmth is most crucial. Lighter insulation underarm and at the yoke retains mobility.
Reinforced Insulation at Heat Loss Areas
In addition to boosted core insulation, the Expedition includes reinforced insulation at key heat loss points. The neck features extra Thermax insulation to retain rising warmth near a major artery. Knees and elbows also include reinforced insulation panels to prevent conductivity from contact with snow and cold surfaces.
Underarm and Back Stretch Panels
Despite the abundance of insulation, Expedition layers avoid bulkiness and restriction of movement thanks to strategically placed two-way stretch panels. Under the arms and across the shoulder blades, stretch polyester knit fabric allows full natural range of motion. You stay warm while remain active.
Smooth Nylon Exterior for Gliding
The outer layer utilizes a smooth-faced nylon fabric to aid gliding across other garments and equipment. This helps the Expedition base layer function smoothly as part of a full layering system. The slick exterior also makes the Expedition easy to take on and off.
Moisture-Wicking and Quick-Dry Properties
Even though warmth takes priority, the Expedition’s outer layer still effectively wicks perspiration away from skin and dries quickly. This prevents the damp soggy feeling wet base layers cause. As perspiration moves outward, the inner insulation keeps working unimpeded.
Antimicrobial Protection
Like all Duofold base layers, the Expedition receives an anti-microbial treatment to prevent odors from sweat buildup. This allows you to wear the Expedition for days on end in the backcountry without getting stinky.
Strategic Seam Placement
Seams are carefully positioned to avoid chafing under packs and weight belts. Off-set shoulder seams prevent rubs and irritation from pack straps. Seams are also placed to avoid pressure points while kneeling and bending.
Long Legs and Ankles
The Expedition includes extra length in the legs so they stay tucked securely into boots without exposing ankles. This prevents snow from creeping in underneath while keeping warmth anchored around feet.
Thumb Loops
Hands pull away from sleeves when layering, exposing wrists. Expedition thumb loops lock the inner layer securely around hands and wrists preventing heat loss.
With deep insights into thermal dynamics and anatomy, Duofold optimized the Expedition’s every detail for sustaining warmth and comfort in the most bitterly cold environments. It is the pinnacle base layer for extreme cold.
How the Expedition uses insulation zones for core warmth
A key factor in the Expedition’s incredible warmth is Duofold’s use of zoned insulation to focus heat retention power where it’s needed most. By mapping varying insulation weights strategically to match anatomy and thermal dynamics, the Expedition provides exceptional core and organ warmth.
Heaviest Insulation Shields the Core
The inner layer of the Expedition base tops use Thermax insulation rated at 200g/m2 in the chest, abdomen and upper back areas. This creates an insulating shield over the critical core organs that must stay warmest to maintain energy and function. The insulation traps rising body heat and reflects it back inward.
Lighter Insulation Underarms and Back Panel
While heavy insulation coats the core, lighter Thermax insulation at 150g/m2 is used under the arms and across the shoulder blades. Mobility would be too restricted in those movement areas with the thickest insulation. The lighter insulation retains excellent warmth while allowing unimpeded arm motion.
Reinforced Insulation at Major Arteries
At the neck where the carotid artery transports warm blood to the brain, extra reinforcement of the 200g/m2 Thermax insulation helps retain rising heat near this vital pathway. Keeping the neck warm prevents rapid heat loss through this critical juncture.
Insulated Panels at Extremities
The Expedition base layer legs also utilize zoned insulation to shield areas prone to high conductive heat loss. The knees receive reinforced insulation panels so contact with snow and cold ground pulls less warmth from the joint spaces. The elbows get a similar treatment to maintain warmth when resting on icy surfaces.
Maintain Core Warmth = Maintain Energy
By focusing its heaviest insulation on the torso core, the Expedition ensures your body retains the warm energy needed to keep functioning and performing, even as the mercury plummets well below zero. Keeping your internal furnace stoked results in less shivering and more stamina.
Allow Flexibility by Zoning Lighter Insulation to Limbs
While the torso core needs to stay insulated above all else, the arms and legs require greater mobility and range of motion. Therefore the Expedition zones lighter insulation at 150g/m2 to the sleeves and legs. This allows you to remain active while still retaining warmth in the extremities.
Strategic Insulation Takes the Guesswork Out
Trying to wear enough insulation evenly across the whole body restricts movement and often leaves cold spots. By zoning heavier insulation only where truly needed for core warmth, the Expedition removes the guesswork and provides protection exactly where required based on thermal dynamics. Targeted insulation at its finest!
Keep Warmth Anchored Around Your Center
The Expedition’s zoned insulation quite literally anchors and retains heat around your core center where it needs to be foremost. Instead of warmth escaping from the torso, it radiates comfortably from the insulating shield right where you need it protecting your organs and energy levels.
Through body mapping insulation weights precisely to match thermal requirements, Duofold ensures the Expedition fulfills its exact mission – shielding your core for warmth in the most extreme cold.
Varitherm’s moisture wicking and thermal regulation
Unlike the Expedition designed for static use, Duofold engineered the Varitherm base layer system for highly aerobic cold weather activities where moisture management and breathability are paramount. Let’s examine how the Varitherm leverages both layers to optimize temperature regulation and sweat wicking.
Grid Fleece Outer Layer for Wicking Efficiency
The Varitherm’s outer layer utilizes a proprietary textured grid fleece featuring raised polyester squares. This unique fabric construction creates air channels that allow heat-robbing moisture to readily evaporate while also trapping warmth in the fleece grids.
Thermal Inner Layer Reflects Body Heat Back
Meanwhile the inner layer employs a soft, thermal knit fabric that hugs the skin and reflects radiant body heat back to you. It creates a thin insulating layer right up against your skin for warmth, but also readily releases excess sweat outward.
Wicking Sweat Keeps You Drier
As you work up a sweat doing winter sports, the inner thermal lining draws moisture through tiny perforations in the grid fleece outer layer. This “wicks” sweat away from your skin so it can evaporate instead of soaking your base layer.
Evaporation Triggers Cooling
As the sweat disperses through the grid fleece and evaporates, the conversion from liquid sweat to gaseous water vapor creates a cooling effect. This prevents overheating and that soggy, clammy feeling of a soaked base layer.
Trapping Heat, Releasing Excess Moisture
So the Varitherm system traps radiant body heat via the thermal inner layer while also using the fleece grid outer layer to provide ample evaporation of excess moisture. This balance is optimized for activities requiring temperature regulation and moisture management.
Strategic Panel Placement Adds Breathability
In high sweat zones like the chest, lower back, and underarms, Varitherm base layers incorporate open-cell mesh fabric panels instead of fleece. These ultra breathable zones allow maximized ventilation and airflow in areas that tend to overheat and sweat the most.
Say Goodbye to Soggy Base Layers
Thanks to the moisture wicking and thermal balancing properties of the Varitherm system, you can finally say goodbye to that awful soggy feeling of sweat-soaked base layers after working hard in the cold. The sweat efficiently moves outward while you stay dry inside.
Consistent Temperature Regulation
Whether you’re hammering up a steep skin track or cruising downhill at speed, Varitherm base layers provide consistent temperature control. As your exertion level and perspiration fluctuates, Varitherm adapts by either increasing cooling airflow or trapping more body heat as needed.
Unimpeded Mobility for Aerobic Activities
Unlike bulky insulating base layers, Varitherm’s smooth, sleek fit allows maximum freedom of movement for winter fitness pursuits. There’s also no chafing or abrasion from the soft thermal inner lining.
Versatile Warmth Across Range of Exertion
Varitherm’s ability to both vent excess heat while retaining warmth makes it versatile across varying levels of aerobic effort. As you slow down, it keeps you warmer. When you speed up, it vents sweat to prevent overheating while working hard.
For high output winter sports requiring temperature regulation and sweat management, Duofold’s Varitherm system is the ultimate performance base layer.
Lightweight, durable materials in Varitherm base layers
In addition to its innovative dual-layer design, the Varitherm system utilizes premium technical fabrics to create lightweight base layers that are also ruggedly durable for active cold weather pursuits.
Stretch Polyester Inner Layer
The inner thermal layer utilizes a custom knit blend of polyester and elastane to provide four-way stretch. This allows unrestricted movement while the polyester retains warmth when damp. The stretch poly knit is soft and smooth for comfort against skin.
Hardier Nylon/Polyester Blend Fleece
Varitherm’s exterior grid fleece is constructed from a proprietary nylon/polyester blend. The polyester provides warmth and wicking, while the nylon fibers add extra abrasion resistance for durability. This creates a rugged fleece.
Strategically Mapped Panel Fabrics
Mesh ventilation panels in sweat zones utilize moisture-wicking polyester microfiber material. It maximizes airflow while dispersing sweat outward. Panel fabrics are mapped strategically based on need.
Lightweight Yet Tough
By engineering the knit patterns and fabric blends, Duofold minimized weight while boosting durability. Varitherm layers feel extremely lightweight, yet the abrasion-resistant fabrics resist rips, tears, and pilling even under rugged use.
Breathability from Synthetic Fibers
The synthetic polyester and nylon fibers naturally absorb less moisture than natural fibers like cotton or wool. This inherent breathability helps vent excess moisture to keep you drier.
Resists Wind Penetration
The dense, stretchy knit inner lining blocks wind from penetrating, keeping warmth right against skin. The grid fleece also resists wind chill thanks to the protective fleece fibers.
Easy Care and Washing
Synthetic fabrics allow Varitherm base layers to be easily washed in any laundry machine without shrinkage or loss of shape. They can be tumble dried without damage.
Focused on Flexibility
Every fabric in the Varitherm system was selected specifically to maximize flexibility, breathability, stretch, and mobility. You stay nimble and unrestricted.
Built for High-Exertion Winter Sports
Varitherm’s blend of lightweight, durable, breathable, stretchy fabrics makes it ideal for extremely active cold weather pursuits from backcountry skiing to winter running. The materials enhance performance.
Duofold pulled out all the stops choosing high-tech fabrics that can keep up with your most aggressive winter workouts while keeping you dry and warm at the same time.
Unique grid fleece in Varitherm for versatile insulation
A key component of the Varitherm system’s temperature regulation is the proprietary grid fleece fabric engineered for the outer layer. This unique grid fleece construction provides versatile insulation for high-exertion winter activities.
Small Polyester Fleece Grids
Varitherm’s grid fleece consists of tiny raised squares of woven polyester fleece across the entire outer surface. This creates a waffle-like pattern of fleece grids surrounded by grooved channels.
Trapping Warm Air in the Grids
The fleece grids act like tiny insulating pockets that trap warm air expelled from the skin close to the body instead of losing it to the cold outside air. This helps retain rising body heat.
Moisture Evaporation in the Channels
Meanwhile, the sunken grooved channels between the fleece grids allow sweat and moisture wicked from the inner layer to evaporate instead of building up. The topography creates evaporation pathways.
Insulation and Breathability in One
This clever grid fleece construction provides both insulation from the fleece grids and breathability from the evaporation channels in one single layer. This saves bulk while optimizing temperature regulation.
Lightweight Warmth
The small fleece grids are able to trap body heat without using thick, bulky fleece fabric. You get ample insulation from the grids without heavy material bulk.
Unimpeded Mobility
Unlike big heavy fleece panels, the lightweight grid fleece flexes easily for unrestricted mobility during active winter sports. The fabric contours with your every movement.
Effective When Still or Moving
Grid fleece provides versatile insulation whether you’re stopped or working up a sweat. When motionless, the fleece grids retain heat. When active, the channels release excess moisture.
Quick Drying
The grooved construction allows sweat to fully disperse promoting quick evaporation so the Varitherm outer layer dries rapidly after getting sweaty during high-exertion activities.
Ample Airflow
Air circulates freely across the grid channels providing excellent overall airflow. This amplifies ventilation and cooling power.
Duofold’s innovative grid fleece unlocks the potential for a base layer to provide ample insulation and breathability in a single construction. Grid power!
Importance of layering Duofold base layers for outdoor activities
While Expedition and Varitherm base layers excel on their own, where Duofold’s system truly shines is when used as part of a complete layering system for outdoor winter activities. The base layers create an ideal foundation to build up a flexible layering system.
Wicking Base Layers Start the System
Duofold base layers sit directly against skin to manage moisture and provide direct skin insulation before anything else. This wicking foundation is critical to pull sweat away so it can evaporate through outer layers.
Adding Mid Layers for Warmth and Breathability
Once the base layer moisture system is in place, mid layers can be added for further adjustable insulation without compromising breathability. Fleeces, down or synthetic insulated jackets provide great mid layer options.
Hard Shells Lock In Heat
Finally, a weatherproof hard shell is added as the outermost layer to protect from wetness and wind while locking in warmth from the base and mid layers underneath. Having a hard shell is crucial for allowing mid layers to breathe.
Use Fewer Layers
Thanks to Duofold’s base layer warmth and moisture management, you can get away with fewer mid and shell layers while retaining excellent warmth and flexibility. Less bulk while staying drier.
Match Layers to Conditions
The beauty of layering lies in the ability to add and subtract layers depending on conditions. As you warm up hiking uphill, shed a mid layer. Put it back on when you stop for lunch.
Keep Your Core Warm
A Duofold Expedition base layer provides critical insulation right against the skin to keep your core and organs warm before anything else. This preserves energy and stamina.
Let Sweat Evaporate Efficiently
The wicking base layers move moisture outward so sweat can readily evaporate instead of soaking layers. This prevents chilling from wet layers.
Stay Warm and Dry
Dry base layers paired with breathable mid layers and a protective shell optimize insulation while preventing sogginess. You stay warm without getting clammy.
Unrestricted Movement
Thinner layers allow better flexibility and mobility than bulky insulation alone. The full system mirrors your body’s movements.
Dial In Adjustable Warmth
Adding and removing mid layers gives you adjustable insulation. Base layers paired with zipped mid layers make it easy to vent excess heat and tune your warmth level.
Taken together as a system, Duofold base layers provide the ideal balanced foundation to build your optimal layered outfit for staying dry and regulating warmth in cold weather adventures.
Using Expedition and Varitherm gear for skiing and snowboarding
When the mercury plummets and winter winds howl, serious outdoor athletes need to stay warm and comfortable. For skiers and snowboarders facing frigid temperatures on the slopes, having the right base layer is crucial.
Duofold’s legendary Expedition and Varitherm baselayers are designed specifically for high exertion in extreme cold. These innovative garments use advanced fabrics and technology to provide warmth, wick moisture, allow ventilation, and maintain comfort during even the most demanding winter activities.
Keeping your core warm
A baselayer is called that for a reason – it’s the first layer and sits closest to your skin. If your core gets cold, your whole body gets cold. Expedition and Varitherm use different fabrics and designs, but both aim to keep your core and extremities toasty even when the windchill dips well below zero.
Varitherm uses a breathable knit thermal fabric with Duofold’s unique dual-layer construction. The inner thermal layer wicks moisture away from your skin while the outer thermal layer provides insulation to retain heat. This innovative design allows for maximum warmth with minimum bulk.
Expedition uses a heavier weight fabric interlock knit from soft merino wool. The natural fibers provide excellent insulation while wicking properties draw sweat away from the body. The Expedition fits a bit looser than Varitherm allowing for greater air circulation to keep you drier.
Venting excess heat and moisture
Working hard on the slopes generates a lot of excess heat and sweat. If that sweat soaks your base layers and can’t evaporate, you’ll end up chilled. Expedition and Varitherm use different techniques to ensure ventilation and moisture wicking.
Varitherm’s snug fit and smooth knit fabric help moisture evaporate quickly. The dual thermal layers maximize this effect. As your sweat passes through the inner layer it meets the drier outer layer and evaporates faster in the open air underneath your outerwear.
Expedition’s looser merino wool knit provides plenty of air space for moisture to evaporate. The wool fibers themselves wick moisture naturally away from your skin. So even if you’re soaked in sweat, the moisture gets drawn out towards the surface where it can evaporate and keep you dry.
Maintaining comfort and range of motion
If your base layers are too tight or too loose it can negatively impact your performance. You want gear that moves with you and doesn’t restrict your motion or cause chafing.
Varitherm uses stretchy, form-fitting fabrics worn close to the skin. This allows excellent moisture wicking and ventilation while providing unrestricted movement. Varitherm fits like a second skin so you’ll hardly notice you have it on.
Expedition uses a relaxed fit and stretch merino wool fabric to allow full range of motion without binding or bunching. The looser fit prevents chafing from skin-on-skin contact during activity. The merino wool has natural elasticity to move and stretch with you.
Choosing the right Expedition and Varitherm for your needs
Duofold offers Expedition and Varitherm base layers for men and women tailored to different types of cold weather activities.
For high output aerobic activities like downhill skiing and snowboarding, Varitherm provides a great balance of insulation, moisture wicking, and ventilation. If you run cold the dual-layer construction provides extra warmth.
For stop-and-go activities like cross country skiing, snowshoeing, and winter hiking, Expedition is a good choice. The looser merino wool makes it more forgiving if you heat up and sweat during high exertion then cool down at rest.
Varitherm works best against the skin as a first layer, while Expedition can be worn over a light synthetic or silk weight base layer for additional insulation in extreme cold.
Expedition and Varitherm also come in different thicknesses depending on the conditions. Varitherm is available in lightweight, midweight and heavyweight. Expedition comes in midweight and heavyweight options. Choose lightweight and midweight for most winter activities, or go heavyweight when temperatures drop dangerously low.

Proper care and washing of Duofold base layers
Duofold’s Expedition and Varitherm baselayers are built tough to handle rugged outdoor use. But proper care and washing preserves the performance and lifespan of these technical garments.
Follow these tips when caring for your Expedition and Varitherm base layers. With the right handling you’ll keep them in top shape for many seasons of winter warmth and comfort.
Always close zippers and velcro before washing
Leave zippers or velcro open during the wash and dry cycles and you risk damaging fabrics. Always secure these closures prior to cleaning.
For zippered Expedition layers, zip them fully before washing. For velcro-secured Varitherm base layers, fasten the hook-and-loop strips before loading in the machine.
This protects the fabrics from catching or snagging during cleaning. Closed fasteners also prevent inner fabrics from bunching or wadding during agitation.
Wash in cold water on a gentle cycle
Frigid winter conditions can expose base layers to grease, oil and mud. But strong detergents and hot wash temperatures damage performance fabrics.
Wash Expedition and Varitherm in cold water using a delicate or gentle cycle. This sufficiently cleans without breaking down water-repellent coatings or elasticity.
When hand washing, use a mild delicate soap. Rinse thoroughly in cool clean water to remove all traces of detergent residue.
Always machine dry on low heat
High heat drying damages the structure and performance of advanced synthetic fabrics and wool fibers.
Machine dry Expedition and Varitherm base layers on the lowest heat setting. This dries the garment while minimizing textile stress and shrinkage issues.
If air drying, lay flat on top of a dry towel. Never hang Expedition or Varitherm – the weight can deform the garment shape.
Wash after each use for maximum freshness
Sweat, body oils and grime build up over time affecting performance and odor resistance. Wash Expedition and Varitherm baselayers after each use.
For heavy use, wash every few wears. Pre-treat any heavily soiled areas. Use an anti-microbial sport wash to inhibit bacteria and odor buildup.
Airing out or spot cleaning between washes saves wear and tear. But a full wash maintains freshness and wicking performance.
Avoid fabric softeners and dryer sheets
Most liquid softeners and dryer sheets use waxes, perfumes and chemicals that reduce wicking efficiency and breathability.
Skip the fabric softener when washing Expedition and Varitherm base layers. Also avoid scented dryer sheets that leave residue behind.
If you prefer a fabric softener, look for hypoallergenic, scent-free liquid or sheet options specifically for synthetics and wool.
Repair small holes and tears promptly
Snags and tears compromise insulating performance. Address minor issues quickly before they expand into bigger holes or runs.
For small holes in Expedition merino, hand darn using wool yarn and a tight stitch. You can also use fabric glue for temporary repairs.
With Varitherm, apply a tiny dab of clear nail polish. For larger holes, patches of ultralight gear repair tape prevent expansion both inside and out.
Deep clean annually with special detergents
Over time, dirt and oils reduce moisture wicking performance. Annually deep clean Expedition and Varitherm with Nikwax Tech Wash or Granger’s Performance Wash.
These specialized detergents purge embedded grime without using harsh chemicals. Follow with a water repellent treatment to refresh beading and wicking properties.
Deep cleaning restores breathability and insulating power for like-new performance season after season.
With proper care and maintenance, your Expedition and Varitherm base layers will deliver reliable warmth, dryness and comfort expedition after expedition, year after year.
