Hoody Warmth

The men's Proton AR Hoody is an exceptionally air permeable, synthetically insulated jacket that performs well as a softshell standalone, and as a mid layer in colder conditions. Its Fortius™ Air 40 outer face fabric balances air permeability with water and wind resistance, while Coreloft™ Continuous synthetic insulation pads the body and hood to provide warmth. This trim-fitting hoody is perfect for November morning jogs through Stanley Park and as layer under your shell on Janruary ski days on Whistler-Blackcomb.

  • Fortius™ Air outer fabric
  • Coreloft™ Continuous 90 and 65 insulations
  • Trim fit, hip-length
  • Arc'teryx Ascent Collection

Insulated Hood | No Slip Zip™ | Pockets

The Proton AR Hoody has a fully insulated hood that is helmet compatible and adjustable. The No Slip Zip™ prevents the front zipper from self-opening, and the dual hem adjusters can prevent up-drafts from working their way inside the hoody. Arc'teryx also gave the hoody two insulated hand pockets and two zippered chest pockets.
