Modern helmet construction hasn’t changed significantly since the adoption of polystyrene impact absorption in the 1960s. But new materials and construction methods are improving safety, in some cases absorbing 30 per cent more energy than their polystyrene equivalents. And you can buy helmets made from them today.

Impacted Koroyd

Wait, polystyrene? Yes, your bicycle helmet, motorcycle helmet or helmet you use for most other sports absorbs impact energy using Expanded Polystyrene (EPS) — the same material used to deliver your last takeaway dinner. It’s actually pretty good at absorbing impacts given its extremely basic nature and is easily spec’d in varying densities to accommodate different deceleration rates for different weight heads. But, its main benefit is that it’s cheap, which is also why there’s little to no measurable difference in safety provided by more expensive helmets versus crappy ones. It’s 2015, surely we can do better.

Enter Koroyd. It’s a new material created by thermally welding miniature tubes together to form a whole that crushes on impact, absorbing energy in a measurable, effective way…
