Just wore these for the first time in the cold rain in Houston and they're bombproof. I stayed dry underneath, the front is wind/water resistant, might be proof, I don't know. The back is kind of like fleece and breathes well but still kept me warm. The zippered ankles and grip prevent any movement. I'm 6'1" 170lbs and the large is perfect.
