Leather motorcycle jackets have been the cornerstone of protective riding gear since motorcycle jackets for the purpose of protection were introduced many decades ago. A leather motorcycle jacket, just like any protective motorcycle leather, should have at least 1.1 millimeter cowhide leather and CE-rated shoulder and elbow protection. Leather jackets can include all types of back protection from temper-foam to beefed up CE-rated armor. RevZilla recommends upgrading to a CE back protector for maximum riding protection. Just about every motorcycle jacket sold by RevZilla will include CE-rated armor in the elbows and shoulders by default, but see the product details for exact specifications.
