The Norvan SL Hoody is the lightest weight, most breathable Arc’teryx GORE-TEX jacket. Weighing a scant 115 grams (4.1 oz), the Norvan SL is an ultra minimalist jacket created specifically for high output trail running in wet conditions. The design utilizes GORE-TEX with SHAKEDRY™ product technology. This watershed technology eliminates the need for a face fabric, significantly reducing weight and increasing breathability while delivering durably waterproof, windproof protection.
