Positive
  • This is such a great and well made jacket; windproof and breathable, yep you read that right! It fits so well and feels great. Their whole line is pretty incredible.
  • After a year, the water repellent wore off. The fabric is durable and cuffs are low profile. The fabric is very stretchy and pulls well. The pockets are placed perfect. It is a great jacket but after a year you will have to upgrade it if you use it a lot like I do. I won’t buy it again though.
  • This is the best on the market no doubt. I have pulled this thing through all the ringers and it is killer. Only thing it can't do is a heavy rain. I highly recommend this baby!
  • Everything about this product is fantastic! It has a great fit and the material is other-worldly. So much offered in this light jacket.
  • This has to be the best breathing soft shell I have ever worn. This thing is totally way better at weather resistance than I could have imagined great technology built into this.
  • This thing is great for average use. The material breathes well and makes it a little less effective for those really windy days. It isn't waterproof but repels well. It isn't for layering either.
  • This company is unbeatable with material and design. The thing fits better than I thought and is really light. It also protects you really well from the elements.
  • This thing breathes well and has a great wind resistance to it. The durability is like no other. It is a soft shell, which isn't my norm, but this is just great. It keeps real mobile and stretches with you well. Definitely good for mixed elements.
  • I have took this all over and done all sorts of extreme sports in it and wow. After a couple years,it is still great. This was meant or climbers as it is made with climbing movement in mind. It breathes so well but is still so wind resistant. Great technology.
  • This is a perfect part of gear for my extreme weather layering. The vented pockets and the material are so good. When it is closed up it will keep you so warm and it is so light. I have had this thing for 4 years now and I am so happy with it, no signs of wear and tear, which means it has epic durability.
  • This thing is great for everything. I wear it all the time. The sleeves are a little too long for me but I do not are it fits and feels great.
  • This is made as an athletic fit jacket so it runs a bit shorter. However, it is the best jacket I have ever owned. It breathes, keeps me warm and ha great mobility. I am a big dude and it works really well. It is expensive but it is worth every penny.
  • I wear this skiing and climbing every year and man is it great. I am able to move all over the place without feeling any constriction and it works so well in cold weather. I never have to bundle up ridiculously. Doesn't cause blind spots in a helmet either.
  • Nothing compares to this jacket. It is so mobile and has never given me and constriction when I am ice climbing. Everything about this is so good. The little layer of fleece keeps you warm and the the pockets air ya out i it gets warm, just open up and AHHHH. I am able to mid layer it as well when it gets real cold.
  • It is very water repellent. It has to be the best fitting jacket I have ever bought and it has a lot of mobility to it. I love that is has so many pockets and they are vented. I got it for hiking but am wearing it all the time now.
  • The new fabric of this is so good. It seems to be way more durable and I own a couple styles of old Arc’teryx jackets. I am really happy with all the pockets and they fabric feels so nice on. The back is longer than the front and helps with those drifts.
  • This thing fits like it was made for my 200 lb fame. It breathes great and sheds water really well. It is super rigid and durable, lasts a year now with not one issue. The best soft shell on the market I can guarantee.
  • This is a very versatile jacket and when you add layers it is unbelievably warm and breathable. It is the best active jacket I have ever bought. It is pricey but worth it if you like to do outdoorsy stuff in weather.
Negative
  • For some reason they made the hand holes way too small. It is awkward and hard to put on. It is also a pain to put on with a long sleeve, it keep pulling them back.
  • Way too much money for this. I would expect ay more for the price. It is an overrated wind jacket that does not really do that. It is so breathy. Not even water proof and it is hard to put on if you have a watch or bracelet on.

Store in a clean dry place. After use in snow or light rain and if moist from sweating let it hang dry.
