Got this gear to wear on those super cold days under the snow pants. They are thin and skin forming enough to not impact the fit of the boot along the lower leg( big deal for performance skiing) and warm enough to keep you on the mountain.

These are made of a good thick material, much like the women ’s cold gear leggings. My daughter likes how soft they are and says they are very warm. We sized up( she is average 9yr old we got M) and she has a little space to grow but they stay up well.

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.

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.

By far the best and warmest product you can buy. The sizing accurate. Spend the money and buy this instead of the cheaper, knock offs that do not perform as well.

Nekita
The fabric is soft, stretchy, and moisture- wicking, so even during intense workouts, they remain comfortable and dry. The 7/8 length hits right above the ankle, which works well for a variety of heights. They also stay in place—no slipping or rolling down at the waist, which is a big plus. The only minor downside is that they run slightly small, so sizing up might be a good idea for a more comfortable fit. Additionally, while they are warm, they aren ’ t overly thick, so in extremely cold weather, you may need another layer. Overall, these leggings are stylish, functional, and ideal for chilly workouts or casual wear. Highly recommend for those looking for warmth without bulk!

K Nicholson
This set is overall one of the best winter base layer fits I ’ ve had the chance to try out in the elements( as of yet). The fleecy layer inside isn ’ t too thick, so it will keep you decently warm while not feeling overly constricting( it won ’ t ruin or take away from your outfit either). If I was to give constructive feedback on anything, it would be that they are a little short in length( mind you, I ’ m 5 ’ 11 ”). So, I ’ m really not picky about that kind of thing( for leggings in particular). Especially as they do have a bit of stretch. I would say that they are relatively true to size, maybe size down if you ’ re on the more petite side of the spectrum.

These are very warm, so perfect under a shell pant or bib for alpine skiing, but I do n't think I would wear them on a tour.
