The Arc'teryx Alpha SV Jacket is a high-performance, expedition-grade hardshell designed for extreme alpine conditions. Crafted with GORE-TEX Pro fabric, it offers superior waterproofing (28,000 mm), wind resistance, and breathability, while maintaining durability against abrasion and UV exposure. Key features include a helmet-compatible StormHood™ with laminated visor, reinforced shoulders and elbows, dual chest pockets with water-resistant zippers, and articulated sleeves for unrestricted movement. The minimalist design in army green ensures low visibility in wilderness settings, while the ergonomic cut allows layering over insulated mid-layers. YKK AquaGuard® zippers and taped seams guarantee full weather integrity. Ideal for mountaineering, backcountry skiing, and severe storm protection, this jacket balances technical rigor with refined aesthetics—reflecting Arc'teryx’s heritage in Canadian alpine gear engineering. Its lightweight yet robust construction makes it a trusted choice for professional guides and serious outdoor enthusiasts seeking reliability in sub-zero, high-wind environments.
