First thing I did was stick them under the faucet. They stayed dry. I only gave them 3 stars because after 3 very specific uses in inclimate weather they have become a little less waterproof. Still comfortable and cozy to begin with but already wearing out. Luckily, we have dryers at work and I bring an extra pair for back up. (Not these, another brand). Also make sure to buy one size up, they run small.
