The ArcTeryx Proton LT Hoody provides midweight air-permeable insulation that self-regulates to prevent overheating.
Adaptable, versatile and designed to manage the dynamic demands of rock, ice and alpine climbing, the highly air permeable Proton LT Hoody performs as a softshell and midweight insulated midlayer. Advanced material technologies balance wind, weather and thermal protection while allowing air to pass freely in and out. This ability to self-regulate helps prevent vapour accumulation and allows the Proton LT to deliver comfort over a wide range of temperatures, conditions and output levels.
