as a biker who wears a leather jacket almost daily, bearing in mind the tremendous amount of money that has to paid, to purchase the jacket, caring for the article is of paramount importance if you desire to keep it for long time. firstly the jacket should be genuine leather, I found that Dubbin is the best solution for keeping your jacket soft and durable, it keeps the jacket waterproof and looking good. I never leave my jacket lying around but prefer to hang it up in the closet on a wooden hanger which supports the shoulders. please contact me if you have any queries.
