there was mention of some internal discussion being leaked to the press which caused the safety authority in sweden to step in, and pause sales - and they subsequently issued a recall of the v3 of the helmet. that killed the company.

they were never legally sold in the states as a helmet as they don't protect from sharp objects as they're not solid.

The main reason seems to be that although they were certified in Europe, they weren't in the US thus denying them access to a big market. I was multi-tasking for chunks of it, but it looks like it was down the the actual test method itself. There were also reports of them going off when parents were bending down to pick up their kid, which considering these were going for about $300 and were single use was a bit much!

Fast forwarding through the video to see the look on your mans face when it goes off is worth it though!

Seem to test ski helmets to same standards as cycling helmets, and…

Swiss Study Says No Helmet Protects Your Head When Skiing or Snowboarding at Real Speed

magicbastarder · 10-12-2025 03:56PM

the headline is misleading, or the journalist (or sub ed) has misunderstood the story.

the study does not show that 'no helmet protects your head at these speeds', it shows that skiers typically ski faster than what the helmets are designed for.

this does not mean that the helmet does not provide any protection at those speeds.

Hmm, this part I'd love more detail on

The most dangerous is an impact that induces head rotation.” In this regard, he downplays the usefulness of the MIPS rotational impact protection system, indicated by a sticker on many helmets: “Having the little yellow or orange sticker doesn’t mean the helmet is good.”

The French version that's mostly translating additionally quotes the manufacturers (Giro, POC, Decathlon and Head who focus on ski helmets) though they don't have much to offer - roughly paraphrased "the test (presumably what the study looked at) falls beyond the standard tests, but they test gear according to legal requirements (which you'd hope!). They don't claim to cater for any scenario, but focus on the majority"

Would a crash on skis at speed generate more rotational impact than coming off a bike on the road? No idea, though MTB might be comparable. There do appear to be studies that show that MIPS bike helmets significantly mitigate against rotational impact, e.g.,

Ski maybe likely to be faster? But I would guess less likely to involve people/ vehicles. Answer is probably "it depends".

magicbastarder · 10-12-2025 05:29PM

i would (based on not much evidence at all) assume that crashing while skiing could result in more 'somersaulting' than cycling, which could lead to repeated chances for the neck and head to be wrenched in different directions?

That bit through me as I thought that was exactly what MIPS was for, not saying I think it works but it at least is designed for something that classic helmets completely fail at.

It depends whether you mean more as in somersaults per person or more somersaults if you somersault. It is probably the same answer if making it a yes/no question but I just wanted to comment, I have seen a lot of cyclists somersault and have done so myself.

(i am talking about something i know nothing of but that never stopped me before)

i guess if we were to compare or contrast skiing with cycling, it's downhilling which would be the closest comparison? if you crash a bike you generally scrub energy quickly, but if you're on a steep slope (which is regularly/mostly the case with skiing) it becomes much harder to come to a stop, as gravity becomes a significant factor. falling and bouncing and rolling also becomes more of a thing i assume when the surface you land on is soft, which can allow parts of your body to dig partly in and cause rotation, rather than allowing you to slide* which would be more common in cycling.

*not saying sliding is a good thing, but in terms of helmets and brain injuries there's less scope for a helmet to make a difference there.

I see that British lawyer "Mr. Loophole" whose career revolves around getting drivers off the hook, wants cyclists to have the same laws as drivers but I'm not sure if he has fully thought it through…

LOL. i refuse to look at the cesspit that twitter is but I presume many have agreed with his call for a helmet on all motorists.
