Arc’teryx Proton Hoody – Breathable Insulation for High-Output Adventures

Lightweight, breathable, and versatile midlayer for climbing and alpine pursuits.

The Arc’teryx Proton Hoody is designed for climbers, mountaineers, and outdoor enthusiasts who demand breathable insulation during high-output activities. Constructed with 80gsm Coreloft™ Compact insulation, it effectively regulates warmth while allowing moisture to escape. The air-permeable face fabric and liner enhance ventilation, reducing vapour build-up during intense movement.

Durable and lightweight, the Fortius Air 20 nylon shell offers abrasion resistance without restricting mobility, while articulated patterning ensures freedom of motion. A helmet-compatible insulated hood extends warmth where it’s needed most, making the Proton Hoody an essential midlayer for alpine climbs, mixed climbing, or any mountain adventure requiring both warmth and breathability.
