SMARTWOOL MIDWEIGHT NEXT-TO-SKIN ZIP-T (MEN'S)

Smartwool's Midweight Zip T is part of their heaviest line, and it is perfect for forays into alpine environments where temperatures -- and schedules -- fluctuate. Comfortable next to the skin, and offering the world’s most efficient moisture-management system.

Because Smartwool fibers wick moisture away while it's still in a vapor state, Smartwool keeps you dry, comfortable, and odor free. Smartwool has a natural crimp that traps thousands of tiny little air pockets that act like insulation for your body. Sythetics have to wait for moisture to turn to liquid before wicking away. Smartwool is more versatile and superior to Synthetics in cold and warm weather because it compliments your body's natural heating and cooling process.
