Arc'teryx Alpha IS Jacket - Men's for Sale, Reviews, Deals and Guides

I'm transferring from Fission SL jacket. I feel that warmth is better for Fission SL, but the collar was soft and somewhat lower, so the feeling of sticking under the chin was improved. The dump pocket on the left inner side is gone, Breast pocket is useful for putting smartphone etc. I wish I could have a through port for passing the cable. The right dump pocket has a stuff sack and can quickly compressed storage jacket. and can quickly deploy just by swinging with a sack. Just because of its adverse effect, since cuffs became like Atom instead of Velcro, gloves open and gaps are open and cold, long gloves will interfere with the cuffs. Also, because the ventilation at the side has gone, sudden waste heat is difficult. These are bothersome when considering excellent storage capacity. The draw code stopper was changed to a button type newly, and it was not exposed to the outside by covering with the seam tape, and the appearance and operability were improved. The zipper strap becomes stick shape made of resin and it is easy to use. Stone is an improvement called Arc'teryx. I think that it can be used for all rounds in any weather like mountains or in the city.

I got this jacket in hopes that it could be my summit jacket. I had previously used the Ceres puffy and an Alpha SV in combination but Arcteryx sell this jacket as a single jacket solution. Out the box I was a little doubtful this would work - it seems very light and thin. It seemed more like a midlayer. Well I am amazed. It sealed out a hard and cold wind (20mph/20F) and maintained a very comfortable temperature. I don't know how they did it but they did. If you have the $ and want to drop a few pounds from the pack - this is a great option. It's my new favorite summit jacket. Wow. Great job Arcteryx
