Unbeatable Warmth-to-Weight.

The men's Atom SL hoody is built for ultra-light protection as a mild weather standalone while excelling as a form-fitting mid layer. It's padded with 40g of Coreloft; Compact insulation, which is highly compressible, hydrophobic, and delivers a superior warmth-to-weight ratio. The sleeves are lined with an airy mesh, while fleece stretch side panels enhance thermal performance and ventilation. A compactable, resilient, and DWR treated Tyono 20 shell completes this hoody's super-light package. This hoody is made to move, with articulated sleeves, gusseted underarms, and a trimming-fit that increases breathability during high-output. An adjustable low-profile StormHood is uninsulated but treated with a water-repellent finish. The full-length No Slip Zipper has a protective chin guard to reduce abrasion and is backed by a breeze blocking wind flap.
