User Review: Arc'teryx Men's Alpha SV Jacket
The Arc'Teryx Alpha SV is one great jacket. I used it recreationally for the first time night skiing last week, and it performed just as I thought it would — with comfort, functionality, and style.
This is, by far and away, the lightest jacket I have ever worn. Once you put it on, you will know what I'm talking about. But even though it's light, that doesn't mean the Alpha SV skimps out on toughness. The ripstop nylon, and 3-layer Gore-Tex not only provide an excellent shell, but a waterproof one as well (note: after a full night of skiing in light to moderate snow shower conditions, not a single part of my torso was wet...something I have never witnessed with a ski parka).
The cut of the jacket (my size is a mens' medium) was perfect on me (5'8", 160lbs), with a snug fit, yet roomy enough to allow several layers underneath. You will have to layer with this jacket. It is still only a shell, and while the Gore-Tex keeps you dry, it alone will not keep you absolutely toasty. It was 25 degrees (F) when I went night skiing, and I was fine with a fleece vest layer and the Arc'Teryx shell.
Additional touches to the jacket include a great structured collar, a powder skirt with in-pocket drawstrings, and very well engineered waterproof zippers (which, next to the weight, are another great design achievement). Overall, a rock solid performer, with unmatched weight, quality, toughness, and design features.
