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 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.

The best pair of cold weather leggings I ’ ve ever had. Period. I told my sister to get a pair and after she wore them the first time she said “ these pants are amazing! ” They are super comfy, they keep you warm in the coldest weather, and they don ’ t slip down. All the pockets are just an added bonus. You won ’ t be disappointed. I quickly purchased another pair.

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.

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!

My favorite pair. I love the way these fit. Not too tight in the ankle/calves for me. I 'm 5' 7 '' and an indoor cyclist so that's usually where pants fail me. Have been wearing to run outside at around 20F and they are perfect! Might even just wear day to day. My only complaint is the small brooks decal started to peel after the first wash.

I ’ ve owned these for a few years but just always remember why I love them after every cold run. Today I shoveled in them for 75 minutes and sledded for 30 and, yes, my skin was a little red underneath afterward, but I was comfortable. The side pocket is clutch, too.

[ I could go on and on about this whole line from Smartwool. It's their best thing in a very long time and I 've been a fan for years. The material is very soft, has a great but comfortable fit. These bottoms also have a nice wide and sturdy waste band so there is no bunching or other uncomfortable nonsense in that area. 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.
