At 0.09mm thickness, the walls of Koroyd’s welded tubes are the world’s thinnest. To give some perspective, the wall of a drinking straw has a wall thickness of 0.20mm.
Despite this ultra-thin wall, the Koroyd core is mechanically very strong and has no weak points.
Normally, when removing material to reduce weight, helmet manufacturers have to compromise on safety because less material thickness can mean less protection.
With Koroyd, that’s not the case. Because the welded tube structure is so light, strong and has better energy-absorbing properties, we can reduce weight whilst improving impact protection. A win-win situation.
