I upgraded to a MIPS helmet from my Tipperary, so got the Uvex Exxential in Jan. It felt good, I could shake my head, bend over and shake again, and the helmet didn’t slip or feel loose/uncomfortable. It has a dial to tighten/loosen it. There’s been a couple times where horse I was on spooked or popped over a fence funny, where the helmet either slipped slightly back or came down a bit in the front. This doesn’t seem right. If I make the helmet SUPER tight, even a hard jerk doesn’t move it. But it is way too uncomfortable to ride in it like this for long. Even if I loosen it one click, then a hard jerk can displace it slightly.
Is this a MIPS thing or does this helmet NOT fit my head? I know the interiors are designed to shift slightly on impact. I’ve felt good in it for months, then I’ll have and unexpected shift, like on XC with a greenie last week. PS: I’ve been riding for over 30 yrs, have had many helmets that never did this. I have an oval head and have comfortably worn Ovation, Tipp, IRH helmets over the years.
