The women's Burton Midweight Base Layer Pants is made with the cotton-like comfort of 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. These stretchy Pants also include an extra-soft contoured waistband, and a fresh-as-a-daisy stink-proof finish.
