SL Hoody

The men's Atom SL hoody is built for ultra-light protection as a mild weather standalone, while also 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 ventilate. This hoody is made to move, with articulated sleeves, gusseted underarms, and a trimming-fit that increases breathability during high-output activities. A compactable, resilient, and DWR treated Tyono™ 20 shell completes this hoody's super-light package.

  • 40 g/m² of Coreloft™ Compact
  • Fleece stretch side panels and mesh under-sleeves
  • Tyono™ 20 shell with DWR finish
  • Trim, slim-fit
  • Weighs 260-grams

StormHood | Full Zip | Shaped Cuffs

The men's Atom SL hoody comes with an adjustable StormHood™, which is low-profile and uninsulated, but is treated with a water-repellent finish. The full-length No Slip Zip™ front zipper has a protective chin guard to reduce stubble abrasion and is backed by a breeze blocking wind flap. The sleeve cuffs are shaped with stretchy fleece fabric for a better fit, while the drop-back hem gives extra protection in the rear and is drawcord adjustable.
