Arc'Teryx Men's Proton LT Vest - Black - XL

Providing core body insulation while maximizing freedom of movement, the highly air-permeable Proton LT Vest performs as a softshell and midweight insulated mid layer. Advanced material technologies balance wind, weather and thermal protection while allowing air to pass at a carefully designed amount. This ability to enable air flow helps prevent overheating and vapour accumulation, allowing the Proton LT to deliver comfort over a wide range of temperatures, conditions and output levels.
