I've worn this jacket - and its prototype - since June and it has quickly become my go-to jacket. That's the jacket that I grab 80% of the time, and have to justify replacing it with something else. I've skied big multi-day tours and climbed long alpine routes in this jacket, and it has a degree of ventilation and stretch that I never thought possible with a Gore-Tex fabric. I'm really looking forward to using it this winter skiing.
This is the best waterproof jacket I've ever used. I had nearly given up on GORETEX and fully waterproof layers for 90% of my days in the mountains, but the Axiom really is much more stretchy, breathable, and slimmed-down than older shells. It isn't as breathable as a light softshell such as the ferrosi, but it is a step in that direction yet the Axiom is 100% waterproof and I've had it out in some big storm days to prove it.I was provided this jacket by OR for product testing/expedition use.
If you want one jacket to take care of you no matter what you're doing, this is it. It's practically a softshell - stretch, soft and crinkle free. And, this new Gore-tex is really breathable - really. For me though, the best part of this jacket is its simplicity... no silly chapstick pocket or stuff like that, just a trim fitting shell with a couple pockets. I expect I'll be wearing the Axiom on most of my adventures for a while now, it's just so much lighter than any comparable softshell. A stretchy, soft, hardshell... Love it.
