Proton Hoody - Women's



The Arc'teryx Proton Hoody is equipped with a breathable insulation package to manage the dynamic needs of mountain pursuits and perform as a self-regulating mid layer for a variety of high-output activities. Breathable insulation means excess heat and moisture can pass through the combination of air permeable fabrics and insulation.

In addition to being extremely air permeable, the Fortius™ Air 20 face fabric has unrivaled hardwearing durability, over 60 times more durable in abrasion tests than the industry standard. Coreloft™ Compact 80 synthetic insulation in the body maintains excellent stretch recovery. The No Slip Zip™ keeps the main zipper from self-opening and the helmet compatible insulated hood gives additional warmth. Put it on, leave it on and stay focused on the activity.

Updated with a revised fit.

The Proton Hoody was previously known as the Proton LT Hoody.
