Bicycle helmets are a useless inconvenience every single moment of their existence except for that one super important one when they protect you from death (or such less punishment). Part of the problem is their shape, which (while a predefined inevitability) is not an efficient use of space. The Tatoo helmet (that comes from the french ‘tatou’ which means armadillo) is made out of flexible (and recyclable!) interconnected polypropylene that unsnaps from itself and packs flat for storage.
The problem here is that the convenience of having a bendy helmet kinda means that the helmet is, uh, bendy. As in not rigid. And last time I checked, rigidity was a rather important part of the whole “protecting your brain from impacts” thing. Good thing it looks like it’s still a concept at this stage.
