S-One

S1 is built on one mission: making the safest, highest‑quality protective gear in action sports. In 2010, after seeing vert skaters, downhill riders, BMX athletes and roller derby players suffer concussions while wearing traditional soft‑foam helmets, the team put those helmets to the test. The results were clear — soft foam let impact energy pass straight through, putting athletes at real risk. S1 responded by engineering the S1 Lifer Helmet, made with EPS Fusion Foam, offering five times more protection and passing both ASTM multiple‑impact and CPSC high‑impact certifications that soft‑foam helmets fail.

S1 goes beyond industry standards by batch‑testing every production run to ensure consistent safety and reliability. Today, the S1 Lifer Helmet and S1 pads are recognized worldwide as the benchmark for quality, innovation, fit and function across skateboarding, roller skating, BMX, bikes, scooters, e‑transport and roller derby.
