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 Fortiusâ„¢ Air 20 face fabric has unrivaled hardwearing durability, over 60 times more durable in abrasion tests than the industry standard. Coreloftâ„¢ Compact 80 synthetic insulation in the body maintains excellent stretch recovery. The No Slip Zipâ„¢ 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.
