S1 Lifer Helmet - Deep Fit Multi-Impact Protection for Kids

Our review of the S1 Lifer Helmet finds it best for riders who need a reliable, comfortable helmet built for repeated impacts. Designed with a Deep Fit Design and a specially formulated EPS Fusion Foam, this helmet aims to combine fit and protective performance for skateboarding, BMX, and roller skating. The single biggest reason to consider it is the combination of Certified Multi-Impact and Certified High Impact ratings that give extra confidence for heavier use by children and adults who push harder at the park.

Key Features

• EPS Fusion Foam: A specially formulated foam core that absorbs and dissipates impact energy to reduce force transmitted to the head.
• Deep Fit Design: Low-profile shell and internal shaping that improve stability and comfort during active movement and tricks.
• Dual Certification: Meets both Multi-Impact (ASTM) and High Impact (CPSC) standards so it is suitable for a wide range of skate and wheel sports.
• Extra Protective: Built to be up to 5x more protective than regular skate helmets according to the manufacturer, offering added peace of mind for higher-risk activities.
• Adjustable Sizing: Includes bonus sizing liners to move one step up or down, making it straightforward to dial in fit for growing kids or different head shapes.

Who It's For

The S1 Lifer Helmet is aimed at families and riders who plan to use a single helmet for several activities - skateboarding, BMX, and roller skating - and want strong protection backed by certifications. It is particularly well suited for riders age 5 and up, including younger kids who need room to grow and adults who prefer a deeper, more secure fit.

Riders who perform only casual, low-speed cruising or who require ultra-lightweight race-style helmets might look elsewhere, but anyone prioritizing multi-impact performance, comfort, and durability will find this helmet appropriate.
