The Lightweight Proton Hoody

The trim-fitting men's Proton LT by Arc'teryx is a super-light, synthetically insulated hoody-jacket that allows for exceptional breathability. It's designed to perform as a mid layer under a shell during cold activities like skiing, and as a comfortable softshell on cool hiking or climbing trips to destinations like the Italian Dolomites. Its Fortius™ Air 40 outer fabric effectively balances wind and water resistance with air permeability, while Coreloft™ Continuous 65 insulation lines the entire jacket, providing consistent warmth.

  • Fortius™ Air outer fabric

Hem Adjusters | No Slip Zip™ | Hooded

The Proton LT has the No Slip Zip™ that keeps the front zipper from self-opening during activities, while the dual hem adjusters prevent cold drafts from working their way inside if cinched tight. Arc'teryx also equipped this jacket with an insulated, helmet compatible hood that you can adjust for optimal protection. Two insulated front pockets keep your hands warm while the two zippered chest pockets serve as spots to store your phone and wallet.
