A top-of-the-line mountaineering and backcountry skiing jacket, the Arc'teryx Men's Alpha SV weighs just over a pound. The use of expedition-tough GORE-TEX Pro Shell fabric, WaterTight zippers, and laminated construction techniques all play a huge role in making the Alpha SV such a lightweight jacket despite its full-featured status. This new line of GORE-TEX is stronger and more breathable than ever before. Micro seam allowances and tiny GORE-TEX seam tape reduce bulk and weight, while also making this first-rate jacket surprisingly supple. WaterTight zippers eliminate the need for bulky, heavy flaps and the laminated construction pulls it all together without the need for fabric weakening stitches and the additional fabric needed to sew one section of fabric to another. Whether belaying from an awkward stance or skinning across a crevasse minefield, the removable HemLock keeps the jacket from creeping out from under your climbing harness. At the same time no-lift gusseted underarms and articulated elbows help the Arc'teryx Alpha SV Jacket remain comfortably positioned so you can focus on the task at hand.
Great Climbing Jacket
This a great mountaineering jacket. Made for severe weather climbing, NOT skiing. Although I wear it everywhere the pockets are designed for use with a harness. Considering what it is made for there is none better!
It's arcteryx
I have the Theta AR and so satisfied so I decided to give this higher model as a birthday gift for my dad. He got extremely happy. Looking at the quality of this one and comparing it w/ my Theta, I'm seriously thinking about buying one for me :)
Great skiing jacket
Perfect jacket for severe weather protection during epic climbs. The drop back hem has rear coverage while allowing front-point visibility. GORE-TEX Pro Shell fabric and a Storm Hood seal out moisture and wind, while the harness HemLock keeps the jacket from lifting out of the harness while climbing.
