The Hot Chillys Women's Pepper Skins Bottoms have a single jersey knit with slight brushing for a soft, lived-in feel. MTF polyester fibers work to transport moisture away from the skin to keep you warm and dry. These ladies' thermal pants have a relaxed fit for everyday comfortable use. Pepper Skins winter leggings feature a flat seam construction for seam strength, durability, and longevity.
