Ralph Lauren RRL Knowles Leather Jacket. We like motorcycle jackets, although we donät want them to be too much “hard rock”, more of that classic look. We like it stripped down and minimalistic, with not too many zippers and strange things going on in the design. This 60‘s inspired biker jacket from RRL fall into that category and it’s a very good looking model. Fully lined and made out of 100% thick high quality cowhide. It got a price tag, for sure, but it is on sale, and we also have a promotional code that works on selected items over at Ralph Lauren.
