A STRUCTURE WHICH IS 95% AIR

Koroyd features the world’s thinnest walled tubes, resulting in a structure which is 95% air.
This reduces weight and enhances comfort without compromising on safety.

Koroyd Tube Wall Thickness

Tube wall thickness of 0.06mm

At <0.06mm 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.

no compromise on safety

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.
