Even in sub-zero temps, you push yourself hard enough to work up a sweat, but ease off for even a minute and a clammy chill sets in – unless you're wearing this fast-wicking Dry on the Fly® Base Layer Crew. Lightweight and bulk-free, it’s a high-tech mix of 85% drirelease polyester with 11% warm, itch-free Merino wool and 5% flexible spandex. So it insulates without limiting your range of movement, naturally resists odor, and pulls moisture from skin in a wick of hurry. Handy thumbholes to prevent sleeves from slipping up. Plus we've added 3" extra body length – won't come untucked or ride up as you reach. Pair the crew with Dry on the Fly Base Layer Pants
for wickable warmth from chin to shins.
