S1 Lifer Helmet - Multi-Impact Skate, BMX & Roller Helmet

Our review of the S1 Lifer Helmet finds it well suited for skaters and riders who want a solid, confidence-inspiring option without unnecessary bulk. Designed for skateboarding, BMX, and roller skating, the helmet's single biggest selling point is its certified multi-impact protection, meaning it is built to handle several impacts rather than just one. The review highlights how the deep fit design and EPS Fusion Foam combine for reassuring coverage and comfort, and notes the convenience of multiple sizing liners that make it easy to dial in a secure fit for riders aged 5 and up.

Key Features

• EPS Fusion Foam: Specially formulated foam provides progressive energy absorption and a durable shell that helps manage impact forces on repeated knocks.
• Deep Fit Design: A lower, more protective shell profile gives better coverage around the temples and back of the head for skate and BMX falls.
• Certified Multi-Impact (ASTM): Engineered to withstand multiple impacts, offering longer-lasting protection during frequent use.
• Certified High Impact (CPSC): Meets high-impact safety standards for skate and roller sports, giving clear regulatory assurance of protection.
• Adjustable Sizing Liners: Includes bonus liners to size one step up or down so you can fine tune the fit without buying a different shell.
• Family Friendly: Recommended for ages 5 and older, making it practical for youth and adult riders who want consistent protection.

Who It's For

The S1 Lifer is best for skateboarders, BMX riders and roller skaters who prioritize protective certifications and a fitted, low-profile look. Riders who fall frequently or use parks and ramps will benefit from the multi-impact construction because it is designed to handle repeated knocks better than single-impact shells.

Those seeking an ultralight competitive race helmet, or a helmet with a full-face cage for downhill BMX, should look elsewhere; this model focuses on balanced protection, comfort, and durability rather than minimal weight or specialized full-face coverage.

Pros & Cons

Pros

• High-impact and multi-impact certifications give clear safety advantages for park and street use.

Cons

• The low-profile, deep fit adds a bit more coverage and perceived bulk compared with minimalist skate helmets.
