Frequently Asked Questions
What certifications does the S1 Lifer Helmet - Watermelon carry?
The S1 Lifer Helmet - Watermelon is dual certified, meeting both the ASTM F-1492-15 multi-impact standard and the CPSC 16 CFR Part 1203 high-impact standard for speeds up to 15 mph. Carrying both certifications is relatively uncommon among skate helmets, since many models meet only one standard or the other. This dual certification is a major reason S1 Lifer helmets are frequently recommended across skateboarding, roller skating, and biking communities.
What does EPS Fusion Foam mean on the S1 Lifer Helmet - Watermelon?
The S1 Lifer Helmet - Watermelon uses a specially formulated EPS Fusion Foam that S1 states is up to 5 times more protective than the soft foam found in non-certified skate helmets. This foam is designed to handle both multiple smaller low-force impacts, common in everyday skating falls, and single higher-force impacts, which is what the dual certification specifically tests for. This is different from single-impact bike helmets, which are generally designed to be replaced after one significant hit.
Is the S1 Lifer Helmet - Watermelon suitable for biking as well as skating?
Yes, the S1 Lifer Helmet - Watermelon is certified for skateboarders, pedal cyclists, roller skaters, and non-motorized scooter riders, making it a multi-use helmet rather than one built for a single activity. This is a common reason riders who split time between biking and skating choose an S1 Lifer over a helmet certified for only one of those uses. Its CPSC certification specifically covers impact protection at speeds up to 15 mph, which is relevant for casual biking as well as skating.
How does the fit of the S1 Lifer Helmet - Watermelon compare to other skate helmets?
S1 markets the Lifer Helmet with a deep fit design, which is intended to sit lower and more securely on the head than a shallow-fit helmet, reducing the chance of it shifting on impact. Riders comparing certified skate helmets often note fit depth as one of the biggest factors in actual protection, since a helmet that sits too high leaves the lower skull less covered. The S1 Lifer Helmet - Watermelon's deep fit is a deliberate design choice separate from its foam and shell materials.
Can the S1 Lifer Helmet - Watermelon absorb more than one impact?
Yes, the S1 Lifer Helmet - Watermelon is certified multi-impact under ASTM F-1492-15, meaning its EPS Fusion Foam is designed to keep protecting after several lower-force hits, unlike single-impact bike helmets that need replacing after one crash. It is also separately certified for a single high-impact event under the CPSC standard. This dual approach is specifically why S1 markets the Lifer as suited to the repeated falls typical of learning tricks, not just one-time protection.
