Headkayse: world’s first multi-impact, foldable bike helmet + video

I saw these at the bike show a few weeks back, and was very impressed. I particularly liked the re-usability of them - multiple impacts - having suffered a collision last year when my head hit some part of the vehicle that drove into me, and also hit the ground when I landed from the subsequent 20 foot flight through the air! Certainly worth a look if and when they come on the market, especially for children and others who might not take care of their helemts as they should.

looks like a sumo wrestler's jock strap...

I love this idea and since it will fit my big head and I admire the vision and entrepeunarial chutzpah of the guys behind this I am getting one. I have been wearing a helmet since the 80's when I wore a large Bell Helmet with looked just like a piss pot and children used to run along the road after me laughing and jeering. Thankfully drivers have avoided me and I have not had to skid along the road on any helmet so I cannot comment on some of the previous opinions voiced. I certainly feel a lot safer with a helmet on so I choose to continue using one. I don't agree with them being compulsory

Interesting to see development of new materials but surely producing a soft shell helmet flies in the face of the established benefits of hard shell construction, not only in the cycling world.

I don't know why the idea of this folding, multi-impact helmet is getting such bad love here. Even just the topic of wearing ANY helmet. True, it's not law in the UK unlike somewhere like Australia but I see it as a form of insurance -- who cares if it doesn't reduce the risk of injury; I certainly like the notion of having my noddle better protected in the event I whack a low branch or one of the many numpty drivers out there decide to cut me up again, etc.

You don't really NEED to wear a seatbelt in the car, but I bet you do anyway 'just in case' (ok, it's law, but you know what I mean).

I also like to wear a helmet so I can put a light on it (something you might not be able to do with this folding one, mind you) or, as a lot of city riders are doing, stick a video camera on there.

I thought the issue with the hairnet/leather type helmet from the 70's, was that a soft outcover grips a little when it hits a hard surface like the road? This means that whilst the head is protected from the initial impact, that tiny bit of extra friction is enough to give more chance of spinal injuries. This is due to the body continuing movement but the head not traveling at the exact same speed. 

Hence the introduction of the hard shell on a helmet which has stayed. 

I'm not sure a "soft" helmet is such a great idea?

Seems to be heading back the direction of the hairnet helmet, the sort they always had in the TDF years ago. When they did use helmets at all.

Not such a bad idea. After all, its hard to find a death by head injury there. Their helmets must have worked. 198 riders, 3500 km, over 100 odd years and only one death by head injury.

Whilst one can only admire the inginenuity and dedication of the designers, they might have found something useful to do instead.  Cycle helmets have never been associated with reduced risk to cyclists, quite the opposite in fact, with helmetted cyclists having more collisions.  So this helmet won't make cycling any safer, but it folds up smaller.  Hmmm, was it really worth the effort?

Perhaps they should have done a little more research cyclehelmets.org
