The S1 Lifer Helmet is one of the best-fitting and safest helmets for roller derby, general skating, skateboarding, road bikes and BMX. The Lifer 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 is up to 5X more protective than the soft foam non-certified helmets. The Lifer helmet 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. THATS RIGHT-- DUAL CERTIFIED! We love this helmet series.

If you need two different size liners-- I personally need a large (black) liner in the back and a medium (tan) in the front. Please leave a note in the comments at checkout.
