Once a week I have to make a 70km commute to work and without fail it has rained each time. I currently don't have a rain jacket and have just been using my leathers - which has proved to be cold, wet and stupid. My questions are; 1. Is this wet riding damaging my leathers (to the point where it may compromise my protection?) 2. I've been thinking about purchasing a motorcycle specific rain jacket, however the thought of just purchasing a larger high vis rain jacket to be worn over the leathers did cross my mind. Would save abit of $$. Does anyone have any opinions for or against this option?
