The Norvan delivers comprehensive GORE-TEX protection with a minimalist design fine tuned for mountain training, running or other high output sports in wet, windy weather. N20p 3L GORE-TEX fabric with GORE C-KNIT backer technology is exceptionally light, highly breathable, soft, supple and delivers durable waterproof breathable protection. The Norvan uses the Arc'teryx Trim fit to help minimize extraneous fabric and keep the material close to the body to maximize its breathability. Articulation in the arms and gussets under the arms elevate mobility and comfort. The top of the cuff is shaped to extend its coverage, and the elasticized bottom hem seals out drafts. The patent-pending 3-layer GORE-TEX fabric with GORE C-KNIT backer technology provides protection with exceptional comfort. The proven bi-component GORE-TEX membrane system is bonded to a dense, extremely thin circular knit to form a supple, less bulky, durable laminate that is more breathable and lighter weight than previous constructions. The circular knit's soft, smooth texture is comfortable on the skin, quiet, and helps the Norvan easily slide on and off over other layers. At only 215 grams (7.5 oz), and with a stripped down minimalist design, the Norvan's features reflect a disciplined focus on performance. The fitted hood provides protection and has an elasticized brim to extend coverage and ensure a high level of visibility. Ingenious Venturi style vents pull air through an opening under the arm to provide continuous airflow while in motion. The construction eliminates the need for a zipper, shaving grams and removing a potential point of irritation. The WaterTight front zipper has a quiet soft pull, an internal laminated zippered pocket stows and protects identification or a small digital device, and reflective blades aid visibility.
