Made for climbers – but not limited to rock and ice – the Proton Hoody is the go-to breathable insulation layer for high-output mountain missions.

80gsm PrimaLoft Gold Active Vent insulation works with the air-permeable face fabric and liner to regulate temperature and vapour build-up. The Fortius Air 20 nylon shell is light and durable, articulated patterning removes restriction, and a helmet-compatible insulated hood extends the warmth.
