Slim Level 2 shoulder armor with airflow

The Alpinestars Nucleon Flex Pro Shoulder Protector is a low-profile shoulder protector designed to fit inside compatible garments for Adventure and Street riding. Built around flexible Nucleon Flex Pro technology, it’s made to conform to the rider’s body shape for an adaptive, ergonomic feel that supports natural movement.

An open, ventilated structure promotes airflow to help keep comfort up on everyday rides and longer days in the saddle. The slim construction is intended to stay discreet once it’s installed in compatible gear, while still delivering certified impact protection for the shoulder area.
