Description from Backcountry.com: The Arc'teryx Alpha SV jacket earned the American Alpine Institute Guide's Choice award, for being a personal storm fortress. You'll appreciate it too when you're high in the mountains and on mother nature's bad side. Contrasting body panels, of Gore-Tex, put more durable fabrics in high wear areas while surrounding your torso in breathability. Welded seams with Tiny Gore taping make the Alpha SV impregnable to both wind and water. The elimination of storm flaps and bulky seams eliminates excess weight and makes this fowl weather friend easily stowed. The new Vislon WaterTight zip is more pliable, weather resistant, and user friendly than previous closures. High, harness-friendly pockets have WaterTight zips to keep electronics, tools, or chow, dry and in close reach. Designed for mountaineering, all pockets and vents are positioned to be accessed while wearing a pack. Gusseted no-lift underarms are destined for summit bids as they let the Alpha SV complete mobility as you reach ever higher.

Bottom Line: This is the Alpha male of the mountaineering pack.
