Test wrote a review of Arc'teryx Alpha SV Jacket - Men's on February 15, 2014
Familiarity: I've put it through the wringer
Fit: True to size
I recently eliminated a good number of rain shells and other technical shells from my gear closet. I now keep just two--a medium and a small Arcteryx Alpha SV Jacket. When Winter mountain trekking I wear the medium to accommodate a down mid-layer sweater and 220 ibex merino wool base-layer. I wear the small size Alpha SV with two Patagonia LS light-weight base-layer shirts and an Atom LT if needed, during spring and fall at altitude when wetter conditions roll in. I also wear Montbell rain pants with either when needed. I'm just over 6' and weigh 150lbs and the jackets and baselayers fit perfectly. These are durable against scrapes with boulders. The new material has 28% greater Evaporative Heat Transfer (heat loss) more than the 2012 model, but still seem to modulate body temperature very effectively. These shells are wind resistant and water proof even keeping my down mid-layer sweater dry. So I'll say it again: The Finest Technical Shell Ever Made!
Instead of getting the Alpha LT I went with the two Alpha SVs and I'm glad I did! I've put these through the wringer at Bryce, Rainier, parts of the AT, rafting the Rogue River and climbing Sisters. I like the slightly too long arm length because it cover the wrists and the storm hood is unbelievably effective. So yeah I'll say it again. Finest Technical Shell ever made! This is one happy trekker and I'been buying technical shells and gear since the late 1960s, but not one compared to these. Buy it!
