S1 Lifer Helmet - Youth & Adult Multi-Impact Skate Helmet

Our review of the S1 Lifer Helmet looks at whether this model is a practical daily helmet for skateboarding, BMX and roller skating. Bottom line: the S1 Lifer is built for riders who prioritize safety and a comfortable fit, particularly families or individuals who want a single helmet that covers multiple high-impact activities; the standout is its Certified Multi-Impact and High Impact CPSC protection alongside a deep, comfortable fit that keeps the helmet stable without feeling bulky.

Key Features

• EPS Fusion Foam: A specially formulated foam construction that is engineered to absorb impact energy over repeated impacts, increasing real-world protection during skating or BMX use.
• Deep Fit Design: The helmet sits lower on the head to improve stability and reduce movement during tricks, giving a more secure feel without restricting comfort.
• Certified Multi-Impact (ASTM): Certification that indicates the helmet is designed to withstand multiple low to medium impacts, which is valuable for park and street riders.
• Certified High Impact (CPSC): Meets high-impact standards for added confidence in higher-risk situations like BMX or aggressive park riding.
• Adjustable Sizing Liners: Comes with bonus sizing liners so you can size one step up or down without buying a new shell, helping achieve an accurate fit for growing kids or mixed users.

Who It's For

The S1 Lifer is best for skateboarders, roller skaters and BMX riders who want a single helmet that covers both multi-impact and high-impact standards; families will value the included sizing liners and the broad age recommendation from 5+ that makes it useful for children through adults. Riders who prioritize visible, comfortable padding and a lower-profile look will find the helmet particularly appealing.

It is less suitable for those who need a full-face downhill or moto helmet, since the shell is optimized for skate/BMX style impacts and not for sustained high-speed motorcycle use. Also, riders who require extremely lightweight race-oriented road helmets may prefer a different specialized model.

Pros & Cons

Pros

• Robust safety credentials with both ASTM multi-impact and CPSC high-impact certifications for versatile use.
• Comfortable, deep-fit shape and good internal padding that many customers praise for fit and feel.
• Includes multiple sizing liners so you can fine tune the fit as head size changes or for different users.

Cons

• Some riders may find the deep fit slightly snug if they prefer a very shallow or ultra-lightweight shell.
• Sizing requires measurement and liner changes; a few users note fitting takes a moment to get perfect.
