Many of the newer generation modular/fullface/threequarter/half helmets use what you have pictured ,,,or,, i simple quick connect/disconnect button,,,,such as what my brain bucket has.
After having gone so long with the old school d-ring setup,,,then going to this sytem,,one of those deals" why didn't i get this a long time ago".
the old die hards will say the d-ring setup 'is safer'. don't know were that comes from honestly?
No experience with the Nolan style pictured connector. I have seen too many of this type fail. http://www.webbikeworld.com/r4/echo-quick-release/ Now, seeing as I never put it together, it may have not been bucled, but the riders that survived swore the were buckled. So much for that.
The D-ring set up is tried, true and seldom fails. Old school? Perhaps. Sometimes it ain't worth fixin, cause it ain't broke. I am sure if demand gets high enough, the buckle system will change too. Just remember, change is just that, not always for the better.
I've had Nolen's for years (102 and 43 Trilogy) and love the strap mechanism. It's a "european"thing, Schuberth, and some of the other european mfgrs' go for 'em. I think Vemar has 'em as well. I am VERY satisified and wish I had the same system on my Arai Corsair. I have never heard or read of anyone having a problem with factory type latches, though there were issues a few years ago with aftermarket "conversions" ....
