Well, I'm the one who knows. I was on a dall sheep hunt in Alaska in August and my buddy had their jacket, pants and gaitors. For 2 days we climbed up about 2500 feet through a creek bed. It rained a lot so the creek was full at about 3-8 inches. My boots got soaked in the first 10 minutes of day 1. After that, he gave me the gaitors to wear. My feet stayed dry after that. I intend to buy some. By the way, his feet stayed dry, wearing their pants.
