Perfect for cool early morning run or hike
November 14, 2011

In the past I would normally would wear multiple top layers but no bottom layers and would freeze my legs off until my body warmed up from a cool early morning run or hike. So I decided to try the Smartwool midweight bottoms after already being a fan of their socks, and newly converted fan of their tops. They were great. My legs were comfortably warm before the run and as I heated up I did not feel humid or stuffy. The bottoms were snug but not tight and soft against the skin. Smartwool has not disappointed me yet so far.

Pros: Great design, Build quality, Great value, great fit, Cons: none
