This is a perfect base layer bottom to compliment your ColdPruf Performance base layer top. The material of this Performance baselayer pant works at the molecular level to wick moisture and insulate at the same time. The single layer design with ColdPruf Technical Fiber performance polyester has an ergonomic women's cut with tagless printing and flat seams for a perfect next-to-skin fit that feels as natural as your own skin. On longer expeditions the antimicrobial properties of the Performance baselayer pant allow you to reuse a single set multiple days in a row without overwhelming odor. This Performance Base Layer women's pant varies from the Extreme Performance base layer women's pant by using just a single layer of material so it will breathe better under high endurance mountain sports in cold to very cold conditions when extreme insulation isn't necessary.
