Arc'teryx Proton Pant W

Arc'teryx Proton Pant W

Materials and design combine in a pant that helps regulate your body temperature across a range of alpine conditions. Wear it as a midlayer in cold conditions, or pull it on as a standalone. The ultralight Octa® Loft knit insulation’s combination of warmth and breathability maintains thermal comfort, and its construction is exceptionally soft next to the skin and eliminates the need for a liner. The trim fit layers easily, and articulated patterning frees you to move.
