None too waterproof after some use
This is a pretty slick looking rain jacket, and is light with good mobility. I definitely enjoyed it at first (hence the 2 stars)!
Unfortunately, after about 10-12 months of regular use (I live in CO where is doesn't rain that much for most of the year) the thing lost its waterproofness almost entirely. I'd be OK in a very light mist, but in a heavy rain I'd look like I'd been hanging out in a hot tub with a sweater on. I tried waterproofing it but it didn't take. I think that must have been my waterproofing skills.
I checked with their warranty department, and they asked me to send it back. Once they got it, they ran some tests and said it was in perfect condition and as waterproof as it should be. Perhaps their definition of waterproof differs from what I'm used to, but I certainly wouldn't depend on this thing to stay dry. Definitely going to look into other options. Looks like another reviewer below had the same experience.
I will say that the ventilation is pretty good. I've not warn it in conditions where I've sweat a lot, but it seems like by opening the pit zips you get some good airflow, so +1 for that.
