Kranium Corrugated Cardboard Helmets

Piercemeear

This fellow is creating bike helmets out of cardboard structures, and making great claims as to their effectiveness. Sound reasonable? I imagine it would be very light.

The structure of Kranium has been developed to absorb the impact energy. The ribs of the structure have been designed to accommodate movement in some places where as it remains perfectly rigid in some areas. Thus during a crash the force peak of the impact is absorbed by the ribs tending to flex and de-flex. The remaining amount of energy is then absorbed by the crumpling nature of the corrugated ribs. When tested against the British Standards (EN 1078) at the Imperial College, Kranium absorbs 4 times the amount of impact energy when compared to regular cycling helmets. This means that during a crash, lesser amounts of energy go into your head thus making it safer than regular cycling helmets.

How does it hold up in the rain?

That occurred to me too, but:

It has also been impregnated with a compound to make the cardboard water-proof.

check out his website, he's designed various covers which also accomodate a strap. i'd be more concerned about the moisture our heads would produce on a sweaty commute... and is the helemt really all that flexible? most of us would be lucky if they fit, not everybody has a head shape like this bloke

The water proofing puts pay to any blood absorbing qualities of the cardboard

I want a reusable helmet. It would make crashing a bit cheaper.
