S1 Lifer Helmet Kids & Adults - Multi-Impact Skate Safety

Our review of the S1 Lifer Helmet finds it to be a thoughtful, safety-first option for skateboarders, BMX riders and roller skaters who want a hard-working, comfortable helmet without bulk. The biggest reason to buy is its certified multi-impact construction: specially formulated EPS Fusion Foam plus a deep fit design that is certified to both ASTM and CPSC standards, making it a clear choice for anyone prioritizing protection during repeated falls or high-impact use. It also ships with bonus sizing liners so the fit can be tuned easily.

Key Features

• EPS Fusion Foam: The helmet uses specially formulated foam that is designed to absorb impact energy over multiple strikes for long-lasting protection.
• Deep Fit Design: The deeper shell profile improves coverage around the back and sides of the head for a more secure, stable fit during active riding.
• Dual Certification: Certified ASTM for multi-impact and CPSC for high-impact, giving confidence for both skatepark and street use.
• Adjustable Sizing: Each helmet includes bonus sizing liners so riders can size one step up or down without needing different shells.
• Durable Construction: Users report solid build quality and durable padding that holds up through regular use and bumps.

Who It's For

The S1 Lifer Helmet is aimed at recreational and intermediate skateboarders, BMX riders and roller skaters age 5 and up who need a dependable helmet that balances comfort with certified safety. Its multi-impact design and deep fit make it particularly well suited to riders who expect repeated knocks or spend time at skateparks.

Less appropriate for those seeking an ultralight race-style helmet or a minimalist commuter model; if low weight or extreme ventilation is the priority, a different design would be better. Also check sizing carefully if you are between sizes, although the included liners do help dial in the fit.
