The ARC 3L Shell Jacket is built for variable conditions, combining a three-layer fabric construction with a 20,000mm waterproof and 20,000g breathability rating to keep moisture out without trapping heat. Fully seam-taped seams, a high collar, and an adjustable hood provide comprehensive coverage against wind and rain. Articulated patterning allows unrestricted movement on the trail or in everyday use, while secure pockets keep essentials protected.
