The men's Burton Midweight Crew is made with DRYRIDE Ultrawick mid-weight 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. This shirt comes stocked with added features including UPF 50+ protection against ultraviolet rays, four-way stretch for mobility, Agion Stink-Proofing, and chafe-free seams for a friction-free ride.
