For impact protection you can wear under any jacket, our HD-Tech Armored Base Layer is an ideal pick. It’s made from a rugged mix of nylon and spandex jersey with mesh panels to promote airflow while you ride. Engineered with body-conforming and remarkably lightweight RHEON^™ armor at the shoulders, elbows, chest, and back. Minimally branded on the front and back so that your favorite Harley Davidson outer layer gets all the attention.
