S1 Lifer Helmet for Skateboarding BMX and Roller Skating S-ONE

Our review of the S1 Lifer Helmet finds it best for riders who prioritize safety without sacrificing comfort or style. Built around a Certified High Impact (CPSC) shell and a specially formulated EPS Fusion Foam liner, this helmet is aimed at skateboarders, BMX riders, and roller skaters who want long-lasting protection for everyday sessions and harder falls. The single biggest reason to buy is its multi-impact capability combined with a snug deep fit design that keeps the helmet stable during tricks and extended wear.

Key Features

• EPS Fusion Foam: The specially formulated foam is designed to manage multiple impacts and reduce transmitted force to the head over repeated low-to-moderate impacts.
• Deep Fit Design: A deeper shell profile provides a secure, stable fit that reduces helmet movement during jumps, spins, and quick turns.
• Certified Multi-Impact (ASTM): Tested for repeated impacts common in skate, BMX, and roller environments, offering more reliable protection session after session.
• Certified High Impact (CPSC): Meets high-impact standards for greater protection on severe impacts that can occur in high-risk riding.
• Adjustable Sizing Liners: Each helmet includes bonus sizing liners so users can move one size up or down for a tailored fit without buying a new shell.
• Recommended Age 5+: Construction and fit options accommodate younger riders through adults, making it versatile for families and progressing athletes.

Who It's For

The S1 Lifer is ideal for riders who take frequent risks or practice tricks that increase the chance of repeated knocks to the head. It especially suits skateboarders, BMX riders, and roller skaters who need a helmet that remains protective after multiple impacts and stays comfortable during long sessions.

It is less appropriate for someone who wants the absolute lightest race-focused helmet or a minimal road cycling shell; those users should look for sport-specific models. Also, buyers who prefer an exact boutique fit without relying on liners may want to try before they commit.
