Really warm underlayer. Used to ski on freezing temp and this plus good ski jacket was enough… even when it was snowing… The only thing is that it feels way different then the 2. 0 shirt. I also have one of that and the 3. 0 is more stiff and feels smaller. Specially in the neck and chest.

mrsguzzie
I purchased this Base Layer 3 shirt when I visited our local outlet store to place an order for another Under Armour shirt I liked. This shirt is thicker than a normal under layer shirt but is still comfortable if you wanted to wear additional layers. The cut of the shirt is super nice you might not want to hide it, though! It has thumb hole openings which are nice. I wore it alone several times since I bought it and was pleased at how well it kept me warm. I liked it so much I went to get a second one. They had sold out of the 3s but I snagged a 2 at least! My only negative comment would be it looks wrinkled when you remove it from the dryer. I only air dried it so maybe some heat might have gotten the wrinkles out. It's black so not that noticeable. Great shirt. I tried to get a 2nd one so obviously am happy with my purchase!

It has a lot of stretch and is great for walking and playing pickle ball. I am 5 ‘ 2 “ tall and weigh 100 pounds and I got them medium children ’s which fits perfect! Arms are just the right length which can be a problem for me in women ’s sizes. I loved it so much that I got two purple ones and one black one!

These pants, as well as the matching shirts, are great for when your son's baseball coach thinks it's a good idea to hold practice in January when it's 38 degrees and no tournament until March! You can put this under any jersey or uniform to keep warm. Do n't mess around with the cheap ones you can find at other online retailers. They 're real thin and do n't add much thermal support. You get what you pay for, and these are not a bad price.

SkiBear33
4. 0 is the best base layer for the price. My kids are competitive skiers in the Northeast. Our winters are harsh and with windchill the temperatures can drop below zero. Using these 4. 0 as base layers helps to keep their heat from escaping. They hold up well through washing and the boys playing/lounging in them after skiing too. They both have two sets, and I only replace once they are outgrown. I just wish they came in more colors.

These are amazing! We love them. ❤️ My dad got my husband and I both a set for Christmas like 10 years ago or more. They are still in perfect condition. We use them for hunting, playing in the snow or anytime we have to be outside for long periods of time in the cold. When I go hunting and it's super cold or wind chill of- 15. I wear mine, my husband's and my under armour sweat pants under my hunting bibs. No need for a heater at all. My son told me he needed some bigger under layers so I automatically ordered him this set. He is going to be so excited when he gets the Christmas morning. If you have multiple children you definitely need to get these. They are such a good quality and will last for years if they are taken care of. The adults sizes are pretty unisex in the bottoms. The woman's top seems to be a little more fitted for the breast.

[ Not quite the perfect fit for my girlfriend, but she says they are very comfortable. We also like that they are machine washable, unlike most heavyweight layers with merino wool. And for the price( around 50% or less the cost of other heavyweight layers) you ca n't beat it!

I bought two of these in preparation of a freezing winter weather storm. I could not be happier with the quality. Theese are great as shirts as well. Seemed a little costly, but well worth it.

The DSG Women ’s Cold Weather Compression Legging is a solid choice for those who want warmth, compression, and comfort in one package. It ’s great for workouts, running, or layering under other clothing for extra warmth. While the fit may run a bit snug, the overall performance makes them a reliable option for cold- weather activities. Would definitely recommend them for active individuals who need performance leggings without breaking the bank!

I received this as a gift and was a bit wary of the material/fit. I get very warm during cold weather runs but this was perfect! Great for layering on a super cold day but warm enough to wear without another layer on a 30 degree day. Ended up purchasing another one. I love them- perfect for running in Upstate NY winters.

My daughter used this a few times this fall during some cold weather softball tournaments. She said it kept her warm. Wasn ’ t restricting during pitching or batting. It has thumb holes to cover your hands when waiting to bat or on the bases. I would say it ’s the same quality as her old Under Armour mock neck shirt but at a better price.

I 'm a tennis player& wear these leggings under a tennis skirt. In winter my outdoor tennis playing requires long leggings& long sleeves. The ColdGear Leggings material has a nice thickness, feels durable, has compression& is soft to the touch inside& out. The waistband is well designed. I like my athletic waistbands around my hip bones; therefore, I adjust all my legging waistbands to personal comfort. I 'm 5' 6 '' _112lbs. I wear UA x- small to be as fitted as possible. I ordered Tall because I like to cover my ankles. This length is about 3/4 '' too long on me, but not a bother since they 're leggings. I like these leggings very much for: Tennis- the compression feels great around my knees& hamstrings. Light Activity- softness, warmth& durability. Lounging- softness& the compression is helpful for circulation.

[ I recently had the opportunity to try out the Smartwool Men's Classic Thermal Merino Base Layer 1/4 Zip, and I must say, it quickly became one of my favorite pieces of outdoor clothing. First and foremost, the quality of the merino wool used in this base layer is exceptional. The fabric is incredibly soft and comfortable against the skin, and it provides excellent insulation and warmth. I was impressed by how well it regulated my body temperature, keeping me warm in colder conditions and preventing overheating during more active pursuits. The natural moisture- wicking properties of merino wool also kept me dry and comfortable throughout my outdoor activities. The 1/4 zip design of this base layer is a great feature. It allows for easy ventilation and temperature control, especially during strenuous activities when you need to quickly release excess heat. The zipper is smooth and durable, and the collar provides added protection and warmth for the neck area. I found the fit of this base layer to be spot on. The slim yet stretchy design contours to the body without feeling restrictive, allowing for a full range of motion. The sleeves are the perfect length, and the shirt stays in place even during active movements. The overall construction feels solid, with flatlock seams that minimize chafing and enhance comfort. One of the standout features of this base layer is its odor resistance. Merino wool naturally has antimicrobial properties, meaning it inhibits the growth of odor- causing bacteria. Even after multiple days of use, the shirt remained fresh and odor- free, making it an excellent choice for multi- day hikes or backpacking trips when laundry facilities may be limited. Durability- wise, the Smartwool Men's Classic Thermal Merino Base Layer is impressive. The merino wool is robust and resistant to pilling, ensuring that the shirt maintains its quality and appearance even after repeated use and washes. I appreciated that it retained its shape and did n't stretch out over time. In terms of improvements, I would have liked to see a small zippered pocket or a media port for storing small essentials or routing headphone cables. This would have added convenience for those who like to listen to music or carry small items while on the move. Overall, the Smartwool Men's Classic Thermal Merino Base Layer 1/4 Zip exceeded my expectations in terms of comfort, performance, and durability. It is a versatile and reliable piece of outdoor clothing that provides excellent insulation, temperature regulation, and odor resistance. Whether you 're hiking, skiing, or engaging in any cold- weather activity, this base layer is a worthy investment that will keep you warm, dry, and comfortable throughout your adventures.

[ I ’ ve worn them all. But smartwool has it figured out. They are the best in the business for warmer base layers. I literally wear the crew neck with a 1/4 zip under my uniform. It provides supreme warmth, breathable base, and keeps you dry. And these are flat out durable.

You don ’ t realize how much you need a heated base layer until you have one! It ’s been such a benefit to various aspects of my life. I wear it beneath my layers when spending time outdoors during winter in Wisconsin. But I ’ ve also worn it to work( in an office) during especially cold days. It fits true to size and is comfy. Somehow it seems to trap heat inside yet it ’s also breathable, I don ’ t sweat in it like I have with other base layers.

The Base Layer Shirt takes the bite out of any cold day! And the battery last for hours! Washed it in a cold wash then hung it to dry, easy peesey! Definitely worth it!

Definitely worth having extra battery banks if you ’ re skiing all day or anything like that, also could use an extra hole in the battery pouch so you can route the cable to a pant pocket more easily. Besides that, it definitely lasts through the wash and multiple winters
