Arc'teryx Proton SL Hoody Men's

* The Proton SL Hoody was previously the Proton Lightweight Hoody.

The Proton SL Hoody is Arc’teryx’s lightest, most breathable insulated option. Updated with recycled Fortius™ fabric for improved durability, and chest pocket and design lines that align with the Proton Collection, it takes the guesswork out of warming up on cold climbs and other high-output activities in cool conditions. The knit insulation holds its loft and shape, no matter how often you stuff it into the bottom of your pack. More importantly, it lets your body breathe, so that you don’t become a sweaty mess after having to step on the gas to get through the crux.
