Product Details

Part of the Arc’teryx essentials collection, the Proton LT Hoody in stylish Dimma is a midweight insulated jacket, ideal for taking alpine, rock and ice climbing. The blend of advanced and lightweight fabrics means this jacket allows you to move freely yet keeping you warm when the temperatures drop. Redesigned for 2019, the Proton LT Hoody now features a Fortius™ Air 20 face fabric which perfectly balances air permeability and weather resistance with lightweight durability. Underneath this is the Air permeable Coreloft™ Compact 80 insulation and Compact 60 in the hood to help regulate your body temperature on those higher output activities. Why not pair with the Gamma LT Pants, a firm favourite with our customers.
