Seat belt type is better all round for me ! And you can clip it back together and carry your lid with the strap...doubles up for a shopping basket !!

So there fore the safest is the D-ring because you adjust it to fit every time you put it on
If I have a big crash (Lets not talk it up ) I'd rather the cut the strap over trying to undo either
I have lost comfy boots and leathers through being cut off but at least I can now walk because I smashed my Tib/ Fib and ankle and heel but my boot kept in all in until the Dr's in hozzy cut my boot and blood flowed freely

It's the only fastener which gets tightened correctly every single time you put it on. The seatbelts tend to get left alone once 'adjusted' for the user and sadly seem to loosen over time - which can be missed by the user for some considerable time. Ask me how insecure I felt when I discovered I could pass all 4 fingers of my gloved hand under the strap on the first (seatbelt-fastened) helmet I ever owned a few months after adjusting it for a snug fit.
As the last thing I want in an off is my helmet moving around - especially if I'm hoping it's absorbing energy from around my skull rather than picking up kinetic energy to pass into it - I'd (now) buy a D-ring every time.
In the case of a spill, I'd expect a professional to be prepared to cut the strap the same way they happily cut your clothing, so the 'easier to undo' claim means little to me - the better fitted helmet could have helped reduce the 'treatable injuries' in the first place.

Hmmm.........I still prefer the seat belt type for shopping with
Seriously, I will hold my hand up and admit that I wasn't aware of the potential effects of the seat belt type. I do adjust mine regular depending on what I wear around my neck/chin. But when you factor in the human element, (forgetfullness) the d type will always be a safer option.
The problem is a lot to do with wanting a particular helmet and not having an option in the type of fastening used. If you want a Caberg Justissimo you get a seat belt fastener fitted. Please correct me if I'm wrong.

Yes and no. the Justissimo GT (that's the new shape one) has a hybrid seatbelt type fastener, but you pass the tab into it, which has a serrated ratchet, (like a ski boot) so you tighten to a specific tightness each time you wear it (like you would a DD) and release the same as a seat belt

I wouldn' t trust on that too much. It still requires the wearer to properly fasten it.
On trackdays we occasionally check the helmets of trainees just before they leave the pitlane. (Virtually) All of them wear D-ring fasteners. with about a quarter of them it is still possible to get at least 2 fingers under the strap and pull it over their chin.
I agree that a D-ring fastener gives you a higher probability of a properly tightened strap, but it is far from a given.

My Nolan helmet has this type too. Much better than the standard seatbelt type - as you say, you just click the ratchet system until the tightness is there.
Feels pretty solid too.

It may take a second longer to put on, much longer for a novice, but it is much more secure and more comfortable.
A cars seat belt self adjust every time it is put on, a selt belt type helmet fastener doesn't.
I wore HJC lids for a while, they went from DD to the sealt belt type and then back to DD after the ACU were considering banning them from the race track.

Double D's for me.
I had a Lazer composite alloy some years back . . . liked the lid but didn't like the buckle, it dug in and was clunky to use.
Shoei TZX now is the daily with double D's and a little tag on the underneath one which helps to undo it.
cheers
