Product Details

The Arc'teryx Men's Proton Hoody is made for climbers who still need real insulation when conditions turn. It’s an ultrabreathable, synthetic-insulation mid layer designed for high-output winter activity, where you need warmth without getting clammy.

The 80gsm Coreloft™ Compact insulation works with the air-permeable face fabric and liner to regulate temperature and vapour build-up. A Fortius Air 20 nylon shell brings light, durable protection, and articulated patterning helps the fit stay free through movement. The helmet-compatible insulated hood adds warmth where you want it. Updated for today with a PFAS-free DWR treatment and Coreloft™ Compact insulation for improved stretch and breathability, plus a Fortius™ Air 20 face fabric using 42% recycled nylon.
