S-One helmets are one of the most innovative fully certified skate & bike helmets on the market, and are renowned for having an incredibly comfortable fit by simply replacing the colour-coded sweat-absorbing liner with a larger or smaller size that suits your head perfectly!
Featuring a super tough ABS outer shell and high impact EPS Fusion Foam; the deep fitting design of the helmet ensures maximum coverage, and the certified foam insulation offers protection against multiple small impacts or a single high impact crash.
Whether you're a regular at the local skatepark or going for a ride to work, school or the shops; the S-One has your head covered!
