Ensure the jacket covers your lower back in a riding position to shield against wind and road debris. Adjustable straps, zippers, and closures enhance fit and flexibility. Key areas like elbows, shoulders, and back should align with protective armor for maximum safety. Avoid overly loose jackets, as they can flap in the wind and reduce protection in case of an accident. A proper fit balances safety, mobility, and style, making rides both comfortable and secure.
