Burton Wool Crew
Here's what other sites are saying:
Burton made the Men's Wool Crew extra-long because it knows all about the pain of bending over to strap in and exposing sensitive skin to cold air. It also made it from a wool blend that's insulating, breathable and odor-repelling, because it also knows all about the pain of a day spent in soggy, stinky underlayers.
