For anyone interested we have a Facebook group devoted to all the MIPS equipped helmets.
The far and away newest and safest helmet is the ARRO which is the only MIPS equipped helmet to have passed the SNELL certification.
Great helmet and they are coming out with a deeper fit and some smaller sizes.
Beyond the Arro, there are all the normal players as well.
We have VT updating their study results every few months and a few more studies coming likely next year. The new FEI mandated Helmet changes should cause some positive changes as well.
If you go to Facebook and search “MIPS Protection System Equestrian Helmets” you will find it.
We have a ton of brand reps, tack shop employees, more info about who carries what and how to be fitted live and virtually. I tried to make a useful group and 5 years and 4900 people later, it’s kicking right along and helping people to choose the best helmets for their heads!
