S1 Lifer Helmet for Skateboarding, BMX, and Roller Skating - Proven 5x

In this review of the S1 Lifer Helmet, the bottom line is simple: anyone who rides skateboards, BMX bikes, or skates and values repeatable impact protection should consider it. The S1 Lifer stands out for its certified multi-impact construction and deep fit design, which combine to deliver a comfortable, secure feel without sacrificing ventilation or style. Our review found the helmet especially compelling for recreational riders and families because it balances durable safety features with practical sizing options that make getting the right fit straightforward.

Key Features

• Specially formulated EPS Fusion Foam: Designed to absorb multiple impacts over time so the helmet can protect in repeated low- to medium-energy events rather than just one crash.
• Deep Fit Design: The low-profile shell and internal shaping keep the helmet stable during tricks and fast turns, reducing distracting movement.
• Certified Multi-Impact (ASTM): Independently tested to meet multi-impact standards, offering reassurance for skaters and BMX riders who face repeated contacts.
• Certified High Impact (CPSC): Meets high-impact consumer safety requirements for everyday riding and park use, giving parents and riders added confidence.
• Bonus sizing liners included: Each helmet ships with extra pads that let you size one step up or down without needing replacement parts.
• Recommended for ages 5+: The sizing approach and included liners make this helmet practical for growing kids and teens.

Who It's For

The S1 Lifer Helmet is best for recreational and intermediate skateboarders, BMX riders, and roller skaters who want a helmet built for real-world use and repeat impacts. Riders who appreciate a helmet that sits lower on the head and stays put during tricks will like the deep fit design.

It is also a solid family option: the included sizing liners and clear guidance for measuring head circumference make it easy to fit children and teens. Riders looking for an ultra-ventilated race-style cycling helmet or a minimalist skate-style shell without multi-impact foam should look elsewhere.
