S1 Lifer Helmet for Skateboarding, BMX, and Roller Skating - High Fit

In this review the S1 Lifer Helmet is recommended for riders who want a solid balance of comfort, fit flexibility, and certified impact protection for skateboarding, BMX, and roller skating. The single biggest reason to consider it is its specially formulated EPS Fusion Foam and multi-impact construction that meet both ASTM and CPSC standards, meaning it is designed for repeated small impacts as well as high-impact events. The helmet ships with bonus sizing liners so you can dial in the fit without buying a different shell.

Key Features

• Specialized foam: The EPS Fusion Foam is formulated to improve energy absorption and reduce transmitted force in falls and impacts.
• Deep Fit Design: The deeper shell hugs the head for a secure, stable fit that feels comfortable during long sessions.
• Certified safety: Dual certification to ASTM (multi-impact) and CPSC (high impact) gives confidence for both park tricks and street riding.
• Adjustable sizing: Each helmet includes bonus sizing liners so you can move one step up or down for a tailored fit without needing extra purchases.
• Durability: Construction and padding choices reported by customers hold up over time, maintaining comfort and protection through frequent use.

Who It's For

The S1 Lifer Helmet is ideal for teens and adults aged 5+ who ride skateboards, BMX bikes, or roller skates and prioritize certified protection and a secure, comfortable fit. Riders who do a mix of park and street riding will appreciate the combination of multi-impact and high-impact certifications.

Less suitable for those who need a very lightweight or full-face motocross-style helmet; this model focuses on urban and park use rather than motorized sports or downhill racing where other specialized helmets are required.

Pros & Cons
