Burton Midweight Crew Shirt 2012: We hate to bash on cotton but nothing keeps you quite as warm and dry as a proper baselayer. The Burton Midweight Crew Shirt is the optimal layering material for high-output activities. Built with DRYRIDE Ultrawick™ stretch jersey fabric that’s scientifically engineered to pull heat-robbing sweat away from your skin and propel it out through your layers. You stay dry, warm, and stoked all day, and since its midweight you get versatile warmth that works all season.
