Meet the Arc'teryx Proton Hoody Men's, your definitive companion for high-output mountain adventures where sweat-inducing ascents meet bone-chilling summits. This technical mid-layer masterfully balances thermal regulation with unrestricted mobility, featuring 80gsm Coreloft™ Compact insulation that works harmoniously with the air-permeable Fortius™ Air 20 fabric to prevent overheating during intense climbs. The articulated patterning moves with you rather than against you, eliminating restriction when reaching for that crucial handhold or ice axe placement. Topped with a helmet-compatible hood, this breathable insulation layer keeps your core temperature regulated precisely when your activity level fluctuates wildly.
Sustainability meets performance with the Proton Hoody's PFAS-free DWR treatment and impressive 42% recycled nylon content, proving technical excellence doesn't have to come at the environment's expense. Three secure zippered pockets—including two hand pockets and a stretch woven chest pocket—keep essentials accessible without compromising movement, while No Slip Zip™ technology ensures nothing opens unexpectedly during your alpine pursuits. Whether you're ice climbing in winter, tackling exposed ridgelines in autumn, or facing unpredictable mountain weather during shoulder seasons, this 415g lightweight champion delivers the breathable warmth that serious mountain athletes demand without the bulk that holds them back.
