This multi-impact helmet from S-One is one of the best fitting and safest helmets for skateboarding, longboarding, BMX and Roller Derby. The Lifer Helmet is a Dual Certified Helmet which means it is ASTM Certified to protect your head from multiple low impacts and CPSC Certified to protect your head from a single high impact.
