The essential particle.
While carrying a jacket for every kind of weather you might encounter may appeal to your inner gear geek, it's a whole lot easier to carry one layer that will handle just about any inclement weather you face in the high mountains. The Arc'teryx Men's Proton LT Hooded Insulated Jacket puts versatility at the top of its strengths with a breathable and weather-resistant softshell face and water-resistant Coreloft synthetic insulation. Arc'teryx's Fortius Air 40 fabric is air permeable to prevent overheating while you're on the move, but resistant to wind, water, and snow when clouds gather over your objective. Coreloft insulation adds lightweight warmth that is quick to dry, whether it gets wet with sweat or snow. Arc'teryx gave the Proton a climbing-specific design with a trim fit to reduce needless bulk, articulated arms and gusseted elbows for climbing mobility, and a hood that fits comfortably over a climbing helmet.
