Arc'teryx Alpha IS

Third, the attention to detail of the features and design of this jacket is a cut above the rest, and fourth, the jacket is competitively lightweight ...

The zipper pulls feel solid and hopefully they hold up over time of tugging. Overall, this product has high quality details that really sets it apart.

I am an huge fan of everything Arc'teryx makes and I first used this jacket over three days of ice climbing in the Canadian Rockies. During this time, there was an inversion going on so often it would be colder at lower elevations. The inversion also resulted in relatively sunny/cold days. Daily tem...

Pros:

This jacket is awesome for cool days and moves with you in the field. Being able to stay warm and protected from the elements without any bulk is great as I trusted this jacket in the field for over a year. Plus, the hood is amazing and secures to your head in strong winds (I have used this...

The drawbacks are that in my typi...

I may have sent it back anyway as I just cant undertsand Arcteryx's decision to add a stretchy non waterproof end to the sleeves. Without gloves and on a rainy day those sleeve ends are going to quickly be...

• Weather-Proofing: I’ve been in 35+mph gusts with wind chills wel...

First of all let me explain why I am a happy owner of this jacket. I had a Fission SL jacket, but both the underarm vent zippers loosened from the jacket, so the insulation started to come out. It also had a small hole on one of the arms. I contacted the Arc'teryx customer service and they told me t...
