The Royal Enfield Classic Leather is made from 100% full-grain leather (1mm) to Class AA standards, with CE Level 2 protectors at the shoulders and elbows. Leather fits close and firm at first and moulds to your body as it breaks in. Royal Enfield leather uses European sizing that runs small, so we recommend ordering one size up from your usual US size. If you prefer a snug, classic fit and don't mind a short break-in period, you can stay closer to your measured size instead.
