Good!

Bought these for my outdoorsman husband. He has been very pleased with the warmth, fit and performance of these. Great price too.

The base layer you will love when its cold and very cold

I’ve tried a number of base layers and have found these to be the most comfortable to wear against the skin. It doesn’t make your skin feel dry. They stretch without noticing it. You don’t tire of wearing these. I want to wear these all winter long. They launder well with negligible shrinkage and no attraction to lint. They never develop a smell. I have spent days wearing these logging over 14000 steps and they still felt and smelled fresh.
