SMARTWOOL LIGHTWEIGHT CREW (MEN'S)

The Smartwool Lightweight Crew is a great primary or base layer for aerobic activity. The high-quality merino wool fibers wick and evaporate to help you stay dry and comfortable. This lightweight crew is versatile, as it regulates body temperature to keep you warm in the winter and cool in the summer. An added bonus-- unlike their synthetic counterparts, the natural wool fibers have an inherent ability to control odors!

"This is one of the lightest, and most comfortable base layers I have worn. Great for trail running!" Mark McKnight, trail runner and Rock/Creek Internet Guru.
