MIPS is increasingly common in rock helmets. Black Diamond (anecdotally the most common brand I see in the US) now has it in their higher end models, and Mammut as well.
Just checked my BD climbing helmet I bought few years ago (seems like Mips Capitan model based on design).
Considered these things a gimmick (any technical equipment bought has list of various tech used within, I generally ignore that by default since I have no idea what each means), happy to see move for more safety in this area. Even small steps matter.
I will climb in big heat wave we have here in Europe now this evening, more sweaty = more slippery on polished rock crags, risk is always not as far as we like to think.
Petzl makes better helmets than BD. They pioneered the ultralight foam kind with the sirocco that everyone (including BD and Mammut) copied. Yet they still don't care about MIPS.
