The Burton Women's Midweight Base Layer Crew Top is the most versatile insulating layer with quick-drying warmth and stink-proof function. It's made with DRYRIDE Ultrawick™ Midweight 200 fabric that's scientifically engineered to pull heat-robbing sweat away from your skin and propel it through your outer layers. You stay dry, warm, and stoked all day, and since it's midweight, you get versatile warmth that works all season.
