Polycarbonates (a type of thermoplastic – in helmet construction, the terms are often used interchangably) are one of the most common materials to make helmets from. It’s incredibly tough and lightweight with masses of impact resistance. It’s also relatively cheap to manufacture so, in many ways it’s the ideal material for crash helmets. Having said that, more expensive helmets tend to be made from more complex composite materials such as fibreglass, carbon fibre or a carbon/kevlar mix. Still, many great performing helmets continue to be made out of polycarbonate – including helmets that score the maximum five stars on SHARP safety tests – so they’re well worth considering.
On this page, you’ll find only crash helmets with polycarbonate shells listed below.
