I just bought a pair of leather chaps. The price was too low to let slide by. The chaps are made by a company called "Choko" which became popular here in Quebec due to it's high quality leather snowmobile attire. The leather is rather thick but very soft and flexible and the upper part is doubled with polyester. I am sure that the leather is water resistant but I doubt it is completely water proof. Has anyone here used a silicone water repellent on their leather chaps and what were the results?
