I've used this about 5 times and love it. Its really light so you barely even notice you have it on. Went camping in Yosemite during the summer and we had unexpected showers for a day. Luckily I had this in my pack and it kept me completely dry. I heat up and sweat A LOT and the pit zips really helped when we went hiking. My only complaint (and it's a minor one) is that it doesn't pack into its own pocket.
