I've been in a driving rain while camping and have stayed dry and cool while wearing this suit. The ventilation is so good that i even used it on a sunny day while fishing and didn't have to put on any sunscreen (it was a windy day, temps inthe 70s)! This rainsuit singlehandedly made my rainy camping trip better, allowing me to work outside in the rain and stay pretty comfortable and dry. It's pretty durable too--i scraped my jacket and pants against rocks, twigs, our aluminum canoe, and several other things and didn't have a problem with tears or rips in the PVC fabric.

One of the concerns i had about the button-up jacket was that if the wearer was in a seated position that water might enter the suit in between the buttons. We take our jetski out on the ocean in rough water, which in analogy would be like sitting on a chair and having someone spray a hose of water at you. Turns out the suit kept me totally dry-- even in serious chop (at one point it felt like we had driven THROUGH a wave of water). The rest of my body (wasn't wearing my pants at the time) was completely soaked, but the area covered by this rainjacket was totally dry. At the end of the trip, it was obvious what part of my body was covered by the suit and what wasn't. Couldn't ask for anything better.

Just an FYI-- the rainsuit only keeps you dry, not warm. So if it's 50 degrees outside, it'll be 50 degrees inside the rainsuit, and since temps generally fall under precip conditions, i recommend wearing a long-sleeve shirt and/or some longer shorts underneath this suit.
