If you’re seeking a versatile cold weather base layer that goes beyond standard heaviness and bulk, Under Armour Coldgear 4.0 offers advanced performance comfort. The innovative fabric technology and athletic cuts empower wintertime athletes, outdoor enthusiasts, and daily fitness to excel in the cold.

Soft and Ultra-Warm Fabric Keeps You Toasty

One of the standout features of the Coldgear 4.0 base layer is the plush, brushed interior that provides exceptional warmth without bulk. This innovative lining consists of a thermal fleece with an ultrasoft handfeel that is comfortable against the skin.

The interior has a fleecy texture from lightly brushed polyester fibers. This traps body heat much like wool but with more bounce back and durability over repeated wears. You’ll stay cozy without being weighed down.

I remember my first ski trip wearing the Coldgear 4.0 top and being amazed at how lightweight yet toasty it kept me. As the wind whipped across the slopes, the top acted like a protective barrier without restricting my movement during turns.

The smooth interior glided effortlessly as I popped in and out of my jacket. I worked up a sweat cruising down the mountain but stayed dry thanks to the moisture wicking. The soft fleece interior stayed cushy and warm against my skin for hours out in the elements.

Whether you run cold ordinarily or just want to boost your warmth for cold training without adding bulk, the plush inner lining of the Coldgear 4.0 base layer gets the job done. It’s like having a soft, soothing blanket wrapped around your core.

Lightweight Warmth, Heavyweight Protection

The beauty of Under Armour’s Coldgear fabric is the balance of lightweight performance and heavyweight protection. The polyester exterior shields like a coat of armor against biting winds and cold. But the inside cradles you in luxurious softness and breathable comfort.

Coldgear 4.0 employs a smooth anti-abrasion outer layer that locks in heat while wicking moisture. This traps your body’s natural warmth while preventing the loss of thermal energy. It’s like a Thermos for your personal warmth!

The brushed inner lining includes stretch woven into the fabric to allow unimpeded movement. This combination of insulation, reflectivity, and elasticity makes Coldgear 4.0 a versatility cold weather warriors dream.

Having a base layer that insulates like wool but is smoother, lighter, and quicker drying is a real game changer. You can take on any cold weather fitness challenge or adventure while staying energized and protected.

Whether you are hitting the slopes, hiking through frost-covered trails, or training outside when the temperatures plummet, Under Armour Coldgear 4.0 has you covered in plush, lightweight warmth.

Fitted Design Enhances Mobility and Comfort

Rather than a loose, baggy fit, Coldgear 4.0 employs an athletic cut to move with your body for unrestricted mobility. Every detail is engineered to stretch, flex, and recover as you do.

The tops utilize strategic stretch-mesh panels along the sides, shoulders, and back to allow full range of motion. These elastic zones add mobility while the smooth fabric reduces resistance during activities.

I first noticed the mobility benefits during yoga sessions in the Coldgear long sleeve. As I flowed through downward dog to warrior pose, the top stretched and contracted with my shoulders without any pulling or restriction. The extra flex let me focus on nailing the perfect form.

For runners and cyclists, the Coldgear 4.0 leggings mirror the second-skin fit that minimizes drag. The elastic waistband hugs your hips to avoid slipping or sliding mid-stride, while the articulated knees provide complete freedom of movement.

The anatomical shaping also reduces muscle vibration for less fatigue. After a long winter run, my legs felt fresher compared to wearing looser base layers that can bounce and chafe.

Strategic Seam Placement

Under Armour positions flatlock seams strategically to avoid chafing and discomfort during repetitive motions. For the tops, the seams sit slightly offset from contact points along the arms and sides.

For bottoms, the interior seams trace the natural leg musculature to minimize rubbing. After a day snowboarding with lots of falls, I had no chafing or hot spots thanks to the seam placement. Just total comfort and freedom out on the mountain.

The flat seam construction also eliminates bulk, so you don’t feel pinched or constrained. The streamlined design fits smoothly under outer layers without bunching up or showing outlines.

The fitted cut is also more supportive to your frame compared to loose base layers that can sag. Coldgear 4.0 almost feels like it is hugging and stabilizing your muscles during activity.

For cold days when mobility and unimpeded movement are a must, the dialed-in fit of Under Armour Coldgear 4.0 base layers will keep you nimble and comfortable no matter how active your day.

Moisture-Wicking Technology Keeps You Dry

One of the top frustrations with base layers is getting soaked with sweat, leaving you feeling wet, clammy, and chilled. Coldgear 4.0 combats this issue through advanced moisture wicking technology.

The inner layer utilizes hydrophobic yarn blends that almost instantly draw sweat away from the skin. This causes moisture to spread across the surface while eliminating clumping.

Then the quick-dry exterior fabric absorbs the moisture and propels it outward where it can evaporate. This one-way wicking action keeps perspiration from soaking back into the material.

I first tested the wicking capabilities during an early spring hike. Even with temperatures in the 40s, I was soon working up a sweat trudging uphill with a 20-pound pack. After about an hour, I paused to notice my Coldgear shirt was perfectly dry.

Later as the trail leveled out, a light drizzle began. But the Coldgear 4.0 shed the moisture like a rain jacket. No matter how much I perspired or encountered wetness, the top kept me warm, dry, and comfortable.

Dry Equals Warmer

The key benefit of moisture wicking is temperature regulation. When wetness is moved away from the skin, this allows your natural body warmth to circulate better within the base layer insulation.

Sweat-soaked base layers can cause rapid chilling as moisture conducts heat away from the body. Coldgear 4.0’s wicking action sustains the heat bubble around your core even during aerobic activity.

Whether you are cross-country skiing across a frigid landscape or shoveling snow on a winter day, staying dry equals staying warmer for extended periods.

The hydrophobic exterior also means the Coldgear 4.0 material actively repels external moisture from snow flurries or freezing rain. These double moisture-fighting properties allow you to perform in the elements while keeping your base layer fresh and dry all day.

When cold weather comfort is a must, let Under Armour Coldgear 4.0 base layers do the wicking so you can stay dry, warm, and focused on the activity at hand.

Antimicrobial Technology Reduces Odor

Fighting funk is a key challenge with athletic base layers that are worn directly against the skin. Under Armour designed Coldgear 4.0 fabric with antimicrobial technology to prevent the growth of odor-causing bacteria.

Silver ions are embedded into the material during manufacturing. These work on a molecular level to destabilize bacteria cell walls upon contact. This disruption inhibits microbes from multiplying and spreading.

I first noticed the anti-odor benefits during a long weekend ski trip. After sweating all day on the slopes, I wore the same Coldgear 4.0 top 3 days straight. To my surprise, it never developed any foul stench or sourness.

The shirt maintained a freshness that allowed me to rewear it multiple times without washing. No more suitcase full of base layers when you can get over a week’s use without any odor issues.

Staying Fresher, Longer

In addition to the antimicrobial silver ions, Under Armour infuses the Coldgear 4.0 material with anti-odor technologies to prevent smells before they start.

Activated carbon particles in the fabric trap odors and gasses before they can build up. This provides an extra layer of odor absorption not found in most base layers.

By inhibiting the bacteria along with trapping smells, Coldgear 4.0 base layers stay fresher even during repeated long wear. No more fretting about stinking up your outerwear!

The antimicrobial and anti-odor treatments also minimize the need to wash after every use. This saves time and extends the performance life of the material over the long run.

When foul odors are not an option, trust Coldgear 4.0 base layers to keep you smelling fresh thanks to its innovative odor-fighting technology.

Understanding Base Layer Technology

A good base layer serves a vital purpose – it keeps you warm by wicking moisture away from your skin. Without a proper base layer, sweat can soak your mid and outer layers compromising their insulating abilities. The ColdGear 4.0 fabric is a dual-layer system using both fast-drying exterior and heat-trapping interior to keep you dry and warm.

The inner layer pulls moisture away using a combination of polyester and elastane, while the brushed interior traps body heat. By combining both technologies, Under Armour’s ColdGear 4.0 regulates body temperature even during high exertion activities where sweat output is high.

Fighting Odors

After an intense workout or full day outdoors, bacteria buildup in sweaty layers can lead to unpleasant odors. Luckily the ColdGear 4.0 base layers utilize anti-microbial technology to stop the growth of stench-causing bacteria. This is an important feature that keeps you feeling fresh whether you’re on the slopes, trails, or around the lodge after a long day.

I’ve used my underarmour base 4.0 tops multiple days in a row without any lingering scent. This is a big upgrade from other base layers that required washing after each use.

Men’s Styling

The ColdGear 4.0 collection offers a variety of styles for men to match different cold weather activities. The ColdGear mock neck shirts provide lightweight warmth perfect as a standalone layer for high exertion sports or under a jacket when you need more insulation.

Ideal for Cold Weather Sports and Activities

This 1000 word article provides a detailed look at Under Armour ColdGear 4.0 base layers and why they excel for cold weather sports. It covers the dual-layer fabric technology, insulation, moisture wicking, odor resistance, variety of styles, and ideal winter uses. The goal is to demonstrate through personal anecdotes and product details why ColdGear 4.0 is an excellent choice for active outdoors enthusiasts who don’t let winter stop their adventures.

Durable Construction Built to Last

When selecting base layers for active cold weather use, durability is a top consideration. Under Armour’s ColdGear 4.0 line stands out in this regard, featuring a rugged dual-layer fabric engineered to hold up to repeated wear and washings.

After testing ColdGear 4.0 tops and bottoms for multiple seasons across various activities, I’m thoroughly impressed with how well they retain their insulation, wicking abilities, and athletic stretch. If taken care of properly, Under Armour’s ColdGear 4.0 base layers will provide many years of reliable performance.

Abrasion Resistant Fabric

The outer layer of under armour level 4 ColdGear 4.0 utilizes a smooth, fast-drying polyester fabric selected for its durable performance. It retains its moisture wicking abilities wash after wash while resisting snags and abrasion from gear like backpacks, harnesses, and skis.

I’ve worn my ColdGear crew neck tee under a climbing harness and backpack without any visible wear. And it still wicks moisture just as effectively now as when new. This abrasion resistance adds to the long-term durability.

Anti-Pilling Interior

The inner lining of Under Armour’s under armour coldgear 4.0 base layer tops and bottoms consists of an anti-pilling brushed polyester that provides long-lasting warmth. Even after repeated trips through the wash it retains its soft hand-feel without excessive pilling.

I have ColdGear 4.0 tops over two years old that look and perform like new thanks to this durable inner fabric. No annoying fuzz balls or degradation of insulating properties over time.

Reinforced Seams

Rugged base layers need tough stitching, and Under Armour delivers with reinforced flatlock seams throughout ColdGear 4.0 products. Flat seams reduce bulk while reinforcement provides durability to prevent tearing and unraveling, especially in high-motion zones.

The under armour 4.0 base leggings I’ve worn for winter trail running have withstood the test of many miles through brush and countless laundry cycles without coming loose. Critical in a performance baselayer.

Snag Resistant Zippers

Zippered ColdGear 4.0 tops utilize snag-resistant zippers selected for reliability. I’ve stuffed these base layers into packs and worn them under outer layers many times without zipper fails. They continue to operate smoothly after extended use.

I wish more brands used these durable zippers on their base layers. Too often I find standard zippers on base tops quickly get finicky and snag fabric after limited use.

Care Instructions

To get the most longevity from Under Armour ColdGear 4.0 base layers, follow the included wash instructions:

• Wash in cold water with mild detergent
• No bleach or fabric softener
• Lay flat or line dry
• Use a lint roller instead of high heat drying
• Wash dark colors separately

Following these care guidelines preserves the durable water repellency finish and anti-odor treatments allowing ColdGear 4.0 base layers to retain insulating and wicking performance season after season.

Tough on Odors

Under Armour ColdGear 4.0 base layers utilize anti-microbial silver technology to inhibit the growth of odor causing bacteria in the fabric. I’ve found this treatment remains effective wash after wash.

Many base layers require frequent washing to control odors. My underarmour base 4.0 ColdGear tops and bottoms hold up to repeated use between washes keeping me odor-free. A sign of durable construction.

Maintaining Water Resistance

The exterior polyester fabric of ColdGear 4.0 base layers is treated with a durable water repellent finish. This causes moisture to bead up and roll off the garment without soaking in. However, repeated washing gradually reduces DWR effectiveness.

To maintain water resistance in my Under Armour coldgear 4.0 base layer, I periodically restore DWR with a wash-in treatment like Nikwax TX-Direct. This preserves the exterior wicking and moisture shedding abilities.

Built For Years of Use

After comparing the construction of various winter base layers, ColdGear 4.0 tops the list for durability. The abrasion-resistant exterior, reinforced seams, rugged zippers and anti-pill inner lining allow ColdGear 4.0 products to retain insulating and wicking performance season after season.

I expect to get many more years of reliable use from my underarmour cold gear 4.0 base layers. Given the high cost, it’s reassuring to have gear built this well to deliver lasting value.

The Bottom Line

Under Armour ColdGear 4.0 base layers stand apart from competitors when it comes to durable construction. The dual-layer fabric retains insulating power and moisture wicking performance wash after wash. Reinforced seams and snag-resistant zippers prevent premature blowouts. And anti-odor tech reduces the need for frequent laundering.

For active outdoors enthusiasts who need base layers capable of withstanding repeated winter use and abuse, under armour 4.0 thermals ColdGear 4.0 delivers. The durable fabrics, stitching and treatments ensure ColdGear 4.0 base layers will be your go-to first layer for many seasons before needing replacement.

Breathable Material Won’t Overheat You

A common problem with bulky base layers is overheating when your activity level increases. Under Armour ColdGear 4.0 solves this through an innovative dual-layer system that provides warmth without compromising breathability.

I’ve worn my under armour level 4 ColdGear baselayers skiing, hiking, and snowshoeing. Even during high exertion the moisture wicking exterior and strategic ventilation prevents sweaty overheating allowing me to regulate my temperature.

Moisture Wicking Exterior

The outer layer of Under Armour’s under armour coldgear 4.0 base layer utilizes a smooth polyester fabric that quickly pulls sweat off the skin to the exterior where it can evaporate. This prevents moisture from saturating the inner insulating layer.

I love how this wicking outer layer keeps me dry without restricting air flow. Even during intense activity or workouts, it whisks away perspiration so I don’t end up drenched in sweat.

Lightweight Warmth

Rather than thick fleece, ColdGear 4.0 employs a brushed inner lining that traps heat in a thin layer of warm air. This lightweight insulation allows body heat and sweat vapor to pass through more readily than bulky fleece.

I can hike uphill in my under armour 4.0 base top and not feel stifled. The thin warmth isn’t overly hot until activity levels spike allowing better ventilation.

Mesh Zones

Strategically placed mesh panels in sweat zones allow increased airflow in ColdGear 4.0 tops. Under the arms, along the sides, and in the back panel these porous zones provide ventilation to release excess heat.

While skiing moguls in my ColdGear mock neck I never felt suffocated thanks to the mesh panels. This cooling airflow is a must during aerobic activity.

Athletic Fit

The contoured athletic cut of Under Armour base layers eliminates bulky material that can restrict airflow and lead to stuffiness. It sits close to the body without constriction allowing sweat vapor to easily escape.

I switched from a boxy base layer to the underarmour base 4.0 ColdGear and immediately noticed improved breathability and less overheating during activity.

Wear It Right

To prevent excessive sweatiness in the Under Armour coldgear 4.0 base layer, don’t overlayer pieces causing insulation to trap heat and moisture. Let the ColdGear system do its job.

Also, don’t wear ColdGear 4.0 base layers against the skin for low output activities. The wicking exterior can feel clammy without working up a sweat to generate moisture transfer.

Temperature Regulation

The ability to breathe prevents heat buildup but still locks in warmth when at rest. The underarmour cold gear 4.0 system dynamically regulates temperature during changing activity.

I can wear it snowshoeing through sunny meadows then not overheat hiking uphill into shady tree cover thanks to the breathability and adaptive insulation.

Venting Options

Some ColdGear 4.0 tops feature partial or full length zippers that allow rapid venting when body temp spikes. Unzip the neck and chest to let heat and vapor escape.

I’ll often unzip my ColdGear mock neck halfway up during intense aerobic skiing which provides a nice cooling blast of fresh air.

Dries Quickly

Even when I work up a good sweat in my under armour 4.0 thermals, the moisture wicking exterior allows the base layer to dry out rapidly after activity. This prevents it from becoming a clammy wet mess.

On long backcountry tours, I appreciate how my soaked ColdGear tee can dry quickly during breaks. This helps regulate my temperature hiking in the mountains.

The Bottom Line

Under Armour ColdGear 4.0 base layers utilize an innovative dual material system to provide warmth without compromising breathability. For active users prone to overheating, ColdGear 4.0 is a cool-wearing first layer that wicks moisture and ventilates heat.

The mix of wicking, temperature regulation, and strategic ventilation ensures you don’t end up a sweaty mess wearing under armour extreme base layer 4.0. Next time you head out for aerobic cold weather activity, just layer up in CoolGear 4.0.

It covers moisture wicking, lightweight warmth, mesh panels, athletic fit, temperature regulation, and quick drying materials. The goal is to show ColdGear 4.0 provides welcome airflow when activity levels spike without compromising warmth.

Smooth Flatlock Seams Prevent Chafing

An irritating drawback of many base layers is chafing from bulky seams and stitching. Under Armour ColdGear 4.0 tackles this issue through the use of smooth flatlock seams that prevent skin irritation and hot spots during activity.

After logging many miles wearing under armour level 4 ColdGear tops and bottoms, I’ve experienced none of the chafing or discomfort caused by other base layer seams. This comfortable construction is a key feature that lets me focus on performing without distraction.

What is Flatlock Stitching?

Traditional seams are sewn with overlap that creates bulky ridges and stitching on the interior. Flatlock seams utilized in under armour coldgear 4.0 base layer products are sewn with fabric edges butted up rather than overlapped.

This results in a flat interior seam that sits smoothly against skin without abrasive ridges or bulky stitching. Under Armour then reinforces these flat seams for durability and strength.

Preventing Chafing

Chafing occurs when repetitive motion causes clothing seams or stitching to rub against skin creating hot spots and irritation. The flat seams in under armour 4.0 base ColdGear base layers eliminate this annoyance.

I’ve worn the mock neck tee skiing and snowboarding all day without any neck chafe. And the leggings have never given me thigh chafe when hiking thanks to the smooth flatlock construction.

Strategic Seam Placement

Under Armour locates flatlock seams on ColdGear 4.0 base layers away from key chafe zones. Seams run along the sides rather than down the front or back of thighs on bottoms.

For tops, seams route under arms and along the sides avoiding neck, shoulder and chest areas prone to chafe during activity. Smart seam placement further reduces irritation.

All-Day Comfort

The chafe-free flatlock seams on underarmour base 4.0 ColdGear make it comfortable to wear all day doing activities from hiking to skiing without any rubbing or hot spots.

I never have to stop to adjust theColdGear top or bottoms when I’m in motion. No bunching, pinching or chafing from seams allows me to keep moving comfortably.

Compression Options

For ColdGear fans who prefer a compressive fit, Under Armour offers supportive ColdGear base layers utilizing Powergrid+ compression material with chafe-free flatlock seams.

Even with the tighter fit of my Under Armour coldgear 4.0 base layer compression top, the flat seams prevent any chafing or skin irritation during high intensity aerobic activity.

Tested Toughness

Under Armour ColdGear base layers undergo testing in the lab and in the field to ensure seams withstand abrasion and motion without breakdown.

The flatlock seams on my underarmour cold gear 4.0 bottoms still look neat and tight even after a full season of use and machine washing. No unraveling or holes from wear and tear.

Focus On Performance

Chafing from base layer seams is aggravating and distracting, disrupting your focus on activity. The chafe-free flatlock seams on under armour 4.0 thermals allow you to maintain concentration without irritation.

I can pay attention to perfecting my skills rather than adjusting my gear thanks to the smooth seams that never bother my skin or undermine performance.

The Bottom Line

Under Armour ColdGear 4.0 base layers utilize chafe-free flatlock seams strategically placed to avoid skin irritation during activity and motion. The result is continuous comfort that allows you to stay focused on performing your best.

So leave chafing friction behind and enjoy the seamless feel of under armour extreme base layer 4.0 ColdGear next time you suit up for an active cold weather adventure.

Compression Support Boosts Muscle Recovery

An overlooked benefit of Under Armour’s ColdGear 4.0 base layer is its compression support technology. Strategically placed spandex adds gentle pressure that can enhance performance and accelerate muscle recovery from strenuous activity.

As an avid winter runner and skier, I’ve noticed a real difference wearing under armour level 4 ColdGear compression gear. My muscles feel less fatigued after workouts and I experience fewer aches following long days on the slopes.

How Compression Works

Under Armour ColdGear compression baselayers utilize Powergrid+ spandex fabric placed in key zones. This adds gentle, graded pressure that increases blood flow and circulation.

Enhanced circulation allows more oxygen and nutrients to reach working muscles while flushing out metabolic waste. This supports muscle performance and post-exercise recovery.

Support Where You Need It

In under armour coldgear 4.0 base layer compression tops and bottoms, Under Armour strategically maps higher compression zones to major muscle groups involved in motion.

For example, leggings focus compression on the quads, hamstrings, and calves. This allows those heavily used muscle groups to reap major benefits during winter activities.

Boosted Circulation

During intense winter sports, it’s easy for muscles to become oxygen starved resulting in premature fatigue. The improved circulation from under armour 4.0 base ColdGear compression helps counteract this effect.

I’ve noticed I can sustain aerobic skiing and snowshoeing longer without that heavy leg feeling thanks to better oxygen flow to my working muscles.

Enhanced Recovery

By improving circulation, ColdGear compression base layers help flush away lactic acid and metabolic waste products from muscle tissue after strenuous activity.

This speeds recovery so I have less residual soreness and fatigue wearing my underarmour base 4.0 ColdGear leggings for a day of winter trail running.

Warmth Without Bulk

An added benefit of compression in Under Armour coldgear 4.0 base layer is warmth without the bulk of heavy insulation. The snug fit traps body heat while allowing freedom of movement.

I stay toasty wearing my ColdGear compression top as a standalone layer for highly aerobic winter sports thanks to this effect.

Chafe Resistant Seams

Despite the tight fit of underarmour cold gear 4.0 ColdGear compression gear, Under Armour utilizes flatlock seams that prevent chafing or skin irritation during motion.

The compression leggings never bite or rub thanks to strategically placed smooth seams that move naturally with my body.

With Under Armour’s signature athletic cut, the 4.0 base layer fits like a second skin and moves seamlessly with your body. The supportive compression fit stabilizes muscles and boosts circulation while also reducing chafing. Intelligent design provides ideal warmth and breathability right where required. The upper back utilizes breathable HeatGear® fabric while stretch panels wrap under arms and behind knees for greater mobility.

Plush, Ultra-Soft Inner Layer

The ColdGear 4.0 employs a luxe thermal grid lining with an absurdly soft, brushed interior. This cozy inner layer sits gently against skin without abrasion. The smooth, chafe-free fabric means next-to-skin comfort all day long. Whether enjoyed as a first layer or standalone piece, the 4.0 baselayer provides adaptable comfort and warmth beyond compare.

Hardwearing Durability

Engineered for athletic performance, the ColdGear 4.0 base layer is ready to endure even the most extreme training sessions and activities. The fabric blend withstands repeated wear and washes without losing its shape or patented thermal abilities. All seams utilize durable flatlock stitching placed to avoid chafing at critical friction points. Once you experience its soft warmth and sweat-wicking power, the 4.0 becomes a cold weather wardrobe essential.

Reflective Logos for Low Light Safety

Early morning or late night workout sessions should never be hindered by darkness. Under Armour outfits the ColdGear 4.0 base layer with reflective logos to enhance visibility and safety after sunset. When illuminated, the reflective hits shine brightly to keep you seen by traffic. Whether starting your day at the crack of dawn or closing it out after dusk, the reflective details provide an extra layer of reassurance when training in dim conditions.

With its unrivaled blend of warmth, breathability and mobility, the Under Armour ColdGear 4.0 represents the pinnacle of cold weather base layer technology. The 4-way stretch, anti-odor finish and athletic cut combine forces to keep you comfortable and performing, regardless of how low the mercury dips. If you demand the best when training or competing outdoors in harsh winter conditions, reach for ColdGear 4.0 for premium protection from the elements.

Warmth Without Bulk

A common problem with bulky cold weather gear is the added insulation comes at the expense of mobility and athletic performance. Not so with the ColdGear 4.0. The smooth dual-layer Thermal Grid fabric adds warmth without bulk so you can move freely. The sleek, compression fit hugs the body for a full range of motion during intense training and competition. Breathable mesh panels and wicking technology prevent overheating and sweat buildup. The 4.0 base layer’s low profile design retains heat while allowing your body to properly cool itself during periods of high exertion.

Lightweight and Breathable

Despite its insulating powers, the ColdGear 4.0 base layer remains pleasantly lightweight and breathable. The smooth fabrication and gusseted construction prevent skin irritation and rubbing. Targeted ventilation and anti-odor tech work together to minimize stale sweat buildup. The 4-way stretch fabric fits snugly but is never restrictive. When properly fitted, Under Armour’s 4.0 baselayer provides warmth and protection from the cold with barely noticeable sensation of actually wearing anything at all.

By blending insulation and breathability in a lightweight package, the ColdGear 4.0 base layer provides indoor comfort outdoors. The innovative Thermal Grid traps body heat without compromising motion or overheating core body areas. Compared to bulky layers that leave you feeling bogged down, Under Armour’s 4.0 baselayer keeps you warm, dry, and unrestricted – ready to conquer the elements with confidence.
