How can I waterproof my Vachetta leather bag?Updated a year ago

We use vegetable-tanned, Vachetta leather to produce the Palissy family and other bag models. So the best option is to use a waterproof spray that is compatible with vegetable-tanned leather. Always spot-test a hidden part of the leather before treating the rest of your bag. Because vegetable-tanned leather is a porous material, it will never be 100% waterproof; however, you can increase its level of water resistance.
