If you need a skateboard helmet, bike helmet, roller derby helmet, roller skate helmet or scoot helmet (non motorized) at S1 Helmets our goal was to make a helmet that we would want to wear and that we could 100% recommend to family, friends and team riders. The S1 Lifer Helmet is constructed with Fusion Foam and is 5x more protective than soft foam skate helmets. The S1 Lifer Helmet is certified to help protect your head from low force multiple impacts (ASTM Standard) and single high impacts (CPSC Certified). We batch test every production run to make sure the S1 Lifer Helmet meets and/or exceeds current helmet safety standards. Great fit, Lightweight and Certified Protection = S1 Lifer Helmet.
