User Review: Arc'teryx Men's Alpha SV Jacket
Source: bought it new
Price Paid: $380
Bought this jacket 10 years ago, and it has served me very well for ten full years of abuse. Multiple times I have slipped while stemming in caves, and the jacket caught me. I have hit many trees skiing, still not a scratch. Oh, and, it's waterproof.
Fit: Gusseted arms are great. Very movable in the jacket. One day in an ice cave, the jacket got wet. When I got outside, it froze. Somehow mobility was not affected.
Adjustability: Good. All Arc'teryx Alpha stuff has the helmet hood, so it's a little crinkled when adjusting to my head.
Water resistance: Waterproof.
Breathability: It has pit zips. Not too breathable, but I'll wear it on a trail run with a T underneath. Keep in mind, my jacket was before Pro shell, or xcr, so this may have improved. Want breathability? Go Active shell from Gore. Think Alpha or Beta FL.
Warmth: It's just a shell, but completely windproof. If you are active 3mph hiking, skiing, kayaking, this will keep you warm in wind and rain down to the upper 30s with just a T underneath. Stuck on a bluff at 2AM, 45°F, with a soaked T shirt underneath, I got cold after an hour and had to build a fire.
Layering: Put a monkey fleece or medium weight down/synthetic underneath, and this will take you about as low as you could go.
Abrasion: The added thicker fabrics in high wear areas are very well thought out. Elbows, shoulders are very long lasting. Climbing off routes where the rocks are extra sharp will not phase this jacket.
Disclaimer: I'm a big fan of Arc'teryx. I wish they would give me this stuff for free.
