[ 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.

[ Love the style. These are very warm and keep me toasty on those cold days. Would recommend to anyone looking for a quality under layers... very cute!

I do n't like reviews that say `` love these '' or some such, since it tells me very little. So... I am 5' 2 and weigh 152 pounds. My inseam is usually 28 inches, no more than 29. I ordered the large and they were perfect in length, landing right at my ankles with a little sag for give in the knees, and for squatting. I have a bit of a straight waist that is short- the waist band is about a 2 inch band that did NOT roll over or down and did not bind so the waist was just right. Fit perfect in the hips, and I have a butt so they stretched without gapping or sagging down in the back. I washed them in warm water, rinsed in cold and hung them up to dry. Dried quickly. They were warm without being hot, did not bunch in the crotch, and I had on jeans over them. Worked outside on the farm and stayed cozy. Went back and bought two more pairs.

`` Heavyweight '' is a little misleading. The fabric is very thin and see- through. On their own, they do n't feel very warm, but worn under jeans or other pants as intended, they function very well. I forget I 'm even wearing them under jeans, and they keep me very warm on cold mornings. A good comfortable base layer. Got the M and they fit great. I 'm usually a 6- 8 in pant size.

[ SmartWool is our go- to for liners. It's well fit, cozy, soft and super warm. It does n't itch and make you warm yet is great to wear inside and on mild days out. Got this one for my wife.

[ I got this a couple weeks ago and it's been perfect, it's of course a great base layer, but for days when too many layers are n't needed it is perfect as a long sleeve T- shirt. Hoping to get a couple more to round out the winter layers
