Atom SL jacket

Lightweight compared to the original, this Atom SL jacket is one of the most practical (and easy-to-pack) items you can own. Wear it alone when running cross-country in wet and cold weather, or wear it with a waterproof shell when extra warmth and comfort are needed during alpine challenges. It is ventilated and breathable, wind and rain proof. The body is made of elastic cotton feather fabric, and the sleeves are made of other fabrics-to maximize packaging compression while still protecting the core warmth. Breathable, lightweight, compressible and packable, wear-resistant, windproof, ultra-thin.
