User Review: Arc'teryx Men's Alpha Comp Jacket
Fabric: 3ply Gore-tex AND Schoeller
Price Paid: $160 USD
This jacket is excellent all around. Similar to the Gamma MX in design, the Alpha Comp is for warmer weather, or higher activity levels. The shoulders and arms and lower part is XCR Gore-tex, while the chest and back is Schoeller fabric. This keeps important areas like kidneys dry and protected from the wind while letting heat escape from the back (very important when wearing a pack).
I got a deal on the hoodless version and like it very much. The four-pocket setup is great. The only thing that I don't like is the mesh lined lower pockets (for venting).
The cut is excellent, the design is excellent, and overall this jacket is well worth the $160 US I spent.
If you can find one on sale, go for it! You won't regret it!
