I needed a better rain jacket (i.e. one that works for torrential downpours and not just light rain) and I got a sweet deal on this one. . . It's pretty much the most amazing thing ever. Weighs less than a pound, packs into the front chest pocket making is small enough to actually stuff in my purse, and is bulletproof in the rain. I'll admit I was a little skeptical at first with how thin it was, but I got to test it out the day after I made the purchase and was thoroughly impressed. Also, my puff fits under it perfectly. The only thing I don't like is that there are no hand pockets, but the sleeves are long enough that I'm over it.
I bought this jacket to wear while climbing. Couldn't ask for a better jacket. It is true to size and the hood actually fits perfectly over my helmet. It keeps me dry without making me sweat up a storm on the inside! Definitely great for anyone looking for a simple perfect addition to your climbing wardrobe!
