Designed for high output trail running in wet conditions and weighing a mere 125 grams (4.4 oz), the Norvan SL Hoody is the lightest weight, most breathable Arc’teryx GORE-TEX jacket. The ultra minimalist 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.
