These base layer bottoms have excellent wicking capabilities, and feel perfectly comfortable against my skin. I stand 6'0", and bought the XL size, which is a little too big. I was worried about my 36" waist, and now know that these will fit comfortably all over and are made to be worn tight. There is no pull or pinching because the material is so silky-smooth, and talk about heat transfer and control -- these things work! I love them -- from winter bike riding, to winter camping, to wearing around the house on cold winter nights! A great buy!

This underwear fits very well. The material is very much like tights but the crotch is full with a fly, which is OK while walking around the house. Probably a good base layer but here in Georgia haven't used it as such because it's been warm.

Great beginning layer for comfort when warmth is not an issue! I use them underneath my pants shell in high activity.

Feels like silk, but much more durable. Waterproof, quick dry, anti-odor, and washer friendly are the major advantages to this high-tech polymer silk. It is great for the warmer months. Clothes easily slide on and off over material and if you're out in the backcountry you don't have to change thanks to the anti-odor system. Marmot products are always better.
