The men's Burton Midweight Base Layer Pant is made with the cotton-like comfort of DRYRIDE Ultrawick Midweight 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. The Midweight Base Layer Pant comes stocked with added features including four-way stretch for mobility, Agion® Stink-Proofing, plus the friction-free comfort of chafe-free seams and a plush waistband.
