Even in summer, the weather can suddenly change. The Arcteryx Atom Lightweight Hoody Insulation Jacket is there for you when the temperature drops.

It's so compact and lightweight, there's no reason to leave it at home. Strategically placed, lightweight and compressible Coreloft insulation at the chest and back warms efficiently. The Tyono 20 outer fabric balances air circulation and weather resistance, while the DWR waterproofing repels moisture. The Arcteryx Atom Lightweight jacket's stretch fleece side panels provide ventilation. The non-insulated hood offers additional protection and can be fixed with buttons when not in use.
