S1 Lifer Helmet for Skateboarding, BMX and Roller Skating - Proven

Our review of the S1 Lifer Helmet finds it best suited to riders who prioritize repeated-impact protection without sacrificing fit or comfort. The standout is its Certified Multi-Impact EPS Fusion Foam construction, which is designed to absorb multiple impacts over time, making it a strong pick for skateboarders, BMX riders and roller skaters who practice frequently or ride in parks. The helmet also includes bonus sizing liners so a single shell can fit a range of head sizes, a helpful detail for growing kids or riders who change hairstyles.

Key Features

• EPS Fusion Foam: Delivers multi-impact energy management so the helmet can protect through repeated knocks rather than only a single crash.
• Deep Fit Design: Provides a secure, low-profile fit that stays in place during tricks, reducing helmet ride-up and unwanted movement.
• ASTM Multi-Impact Certified: Meets performance criteria for multiple impacts typical in skate park and street use, offering confidence for frequent riders.
• CPSC High Impact Certified: Complies with high impact safety standards for added protection during harder impacts common in BMX and skating falls.
• 5x More Protective: Marketed as delivering up to five times the protection of regular skate helmets, emphasizing its heavy-duty safety focus for active riders.
• Sizing Liners Included: Comes with bonus liners to size one step up or down, helping achieve the right fit without buying a different shell.

Who It's For

The S1 Lifer Helmet is aimed at regular skateboarders, BMX riders and roller skaters aged 5 and up who need a helmet built for repeated use and stronger impacts. Its certifications and construction make it especially useful for park riders, instructors, and anyone who practices in environments where falls and multiple impacts are likely.

Less appropriate for casual users who only ride very occasionally and prefer ultra-lightweight street helmets, or for riders who require full-face protection for high-speed downhill riding. Those users should look at helmets tailored to those narrow needs.

Pros & Cons

Pros

• Multi-impact EPS foam offers lasting protection across multiple falls rather than only a single event.
• Deep fit design and included sizing liners make it easier to get a secure, comfortable fit for different head sizes.
• Dual certifications (ASTM and CPSC) provide reassurance that the helmet meets respected safety standards for skating and BMX use.

Cons

• The design emphasizes protection and durability, so it may be heavier than minimalist street skate helmets preferred by some casual riders.
