S1 stands for Safety First — every ride starts with protection. The S1 Defense Youth Jackets are designed to shield young riders from the first impact without sacrificing comfort or mobility. Lightweight, breathable, and anatomically shaped, these protection jackets use advanced materials like Kevlar, SmartFoam, and memory PU to provide world-class safety for BMX, MTB, moto, and beyond.
Choose from three levels of protection:
-
S1 Defense Pro 2.0 – Lightweight and comfortable with EVA + foam pads and Kevlar elbow panels.
-
S1 Defense Elite 2.0 – Upgraded shock-absorbing foam and full-length YKK zipper for easy fit.
