The Arc'teryx Alpha SV Jacket is a high-performance, expedition-grade hardshell designed for extreme alpine conditions. Constructed with GORE-TEX Pro fabric—evident from the official tag attached at the collar—it delivers 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 reinforced brim, dual-adjustable cuffs, YKK AquaGuard zippers on all pockets and main closure, and articulated patterning for unrestricted mobility. The minimalist black aesthetic features subtle embroidered Arc'teryx logo on left chest and signature bird silhouette. Reinforced shoulder and elbow panels enhance longevity during technical climbing or backcountry skiing. Ideal for mountaineering, ski touring, and severe weather hiking, this jacket balances technical rigor with refined design. Its lightweight yet robust construction ensures reliable protection without bulk, making it a top-tier choice for serious outdoor athletes seeking uncompromising weather defense in winter and transitional seasons.
