Yeah I won't be riding it in the rain I just purchased a 59 schwinn tiger off another member and I wanted this seat because it will go great with the bike I feel it just goes with the eraI have owned two Brooks saddles and they didn't last long. It is too wet here. The weather looks nice, then after work it is raining. I had a shower cap I put over it to protect it but the water comes up off your wheels and soaks the leather from underneath. I think fenders would have helped but I had them on road bikes. The comfort is unmatched in my opinion, but I don't use them anymore, there are a lot of other non leather seats that are comfortable and I don't worry about the wet. I probably will buy another one sometime because of the comfort.
Be careful I read that proofing them too much will soften the leather to much and make it deteriorateDepends on how much you ride on it, weather conditions its in, try not to let it get wet etc i ride once in a while in winter as its too cold to ride and bikes indoors so i proof it once in two months, in summer i ride more often so once a month to 6 weeks so it does not need doing that often.
