Description
The lightest, most breathable option in our Insulation Collection, the Proton SL Hoody 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 allows your body to breathe, so you’re not left a sweaty mess after you have to step on the gas to get through the crux.
What's been updated: Updated with recycled Fortius™ fabric for improved durability, and chest pocket and design lines that align with the Proton Collection.

NOTE: Men's fit has been updated with a revised fit. Medium size remains unchanged. Smaller sizes are now tighter and larger sizes are now looser. Arc'teryx sizes are intended to fit the above body measurements. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.

Our trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over first layers or under outer layers.
