The Arc'teryx Gamma MX is engineered for dynamic alpine pursuits where weather shifts demand responsive layering. Its hybrid construction combines stretchy softshell panels with reinforced nylon in high-wear zones, delivering exceptional mobility without sacrificing durability. The brushed fleece lining traps warmth while maintaining breathability, making it ideal as a mid-layer or standalone piece in cool conditions. Pit zips provide rapid ventilation during intense activity, while the articulated sleeves and gusseted underarms ensure unrestricted movement. Designed for climbers, skiers, and mountaineers who refuse to compromise between protection and performance.
