The S1 Lifer Helmet is one of the best fitting and safest helmets for skateboarding, longboarding, BMX and roller derby. This helmet uses a specially formulated EPS Fusion Foam which allows it to protect your head from multiple low force impacts as well as high impacts.
The Lifer Helmet is a Certified "multi-impact" helmet and up to 5x more protective than the soft foam non-certified helmets. This is a break through design combining the added safety of a CPSC and ASTM certified helmet with the comfort and fit of a non certified helmet.
Sizing: The S1 Lifer helmet fits 20.5" - 23.5". You can adjust the sizing of each shell by using thicker or thinner sizing liners. The sizing liners are colour coded by thickness.
