It works because of Enkayse

Hedkayse One conforms to safety standards hit after hit.

Of course Hedkayse One conforms to safety standards in Europe. But Hedkayse One is no fragile one-hit wonder.

Because of Enkayse, Hedkayse One is able to pass safety tests after multiple impacts. That’s pretty impressive considering the size of a single test impact alone is fairly fierce.

Conventional helmets are made from polystyrene. In a large impact polystyrene deforms to provide what’s known as “sacrificial protection”. This is why you have to be careful not to drop your polystyrene helmet in everyday use, and it’s why manufacturers recommend that you replace your helmet after a knock.

Enkayse is designed to work differently. It manages the energy of impacts, so it can retain its integrity after more than one impact, large or small.

Because Enkayse dissipates energy rather than deforming on impact, it also cushions small bumps. Polystyrene can’t do this, since forces which are too weak to deform it are transmitted through. Enkayse provides comfort in protecting from small bumps. This may also have long-term benefits as researchers believe the cumulative effect of small knocks contributes to brain disease over time.

Because Enkayse shrugs off little bumps, it means that Hedkayse One is durable against the knocks and scrapes that come with everyday use. You can be sure that Headkayse One will stand up to the daily grind.

How we test this


Helmet testing standards

If you're interested in really understanding how helmets work and whether a polystyrene helmet is any good - then you're in luck. Our very own Andrew has written an illuminating article which gives you the lowdown on helmet physics, how the standards work and how we can change things for the better. Enjoy the read!
