Rated 5 out of 5 by from Ridiculously lightweight! Just got this in the mail today. Man is it light. Not sure how durable it will be, but this packs nice and small - about the size of my fist when put in its stuff sack. The material is different from most other rain jackets I've tried on - it's very comfortable. I don't plan on running in it, but with it's size and hopefully being as breathable as they say, should be great for some upcoming trips to Southeast Asia. I'm 5'8'' 140lbs. I got the medium and it fits well. It still has enough room to layer it over a sweatshirt etc.

Rated 5 out of 5 by from Most breathable shell ever, stuffs away to nothing An absolutely brilliant piece for trail running, sculling or nordic skiing where you will not need to wear any packs, harnesses, etc. over the top of it. Packs down to nearly nothing and more completely delivers upon the Gore-Tex breathability promise in highly aerobic situations like no other garment I've ever worn - you can visibly see the vapor accumulating on the outside when you start heating up... And this jacket is even _more_ compact than my trusty old Hoodini jackets which by comparison now seem antiquated in functionality and protection for more intensive alpine running pursuits in comparison... Indispensable for its intended purpose and also an absolutely brilliant travel piece. The exposed membrane on the exterior of the jacket is worrisome in the long term as it has low abrasion resistance, so plan on wearing this over the top of any hydration vest or running backpack. Definitely not for those who are tough on gear. I'll update with a review on durability after the six month mark with how it holds up after extended use and laundering. Overall, this is minimalist design of the highest order that cuts no corners in functionality. Kudos to the designers at Arc'teryx - please, more like this for us price-no-object ultralight nuts!
