ARC’TERYX Arc'teryx Atom Heavyweight Hoody Men's Atom Heavyweight Hoody Men's Domestic Genuine Product Brand new, unused with tags Size: S Color: Black I am selling this because I bought another down jacket and have been wearing that instead, so I haven't had a chance to wear this one. It is definitely a genuine product. Warm, breathable, windproof, and weather-resistant, this is a durable and packable piece. The Atom Heavyweight Hoody, which can be worn as a mid-layer in cold climates or on its own during rest, is one of Arc'teryx's most versatile high-insulation items. Coreloft™ synthetic insulation provides efficient warmth and is also resilient. The lightweight, wind-resistant, and water-repellent Tyono™ 30 shell is treated for durability, and Permeairm panels under the arms improve ventilation. The helmet-compatible, high-insulation hood provides extra warmth and protection.
