While it's not "proven" that MIPS helps anything, it's dead certain that rotational injury is a problem for TBI and very plausible that MIPS reduces the angular acceleration. So I have no qualms about taking it on face value.
Maybe.. but it's been reported that MIPS helmets have in the instructions (who reads those, right?)
not to wear with hat/liner underneath. What season are we in? That's a non-starter for me, who prefers a liner even in summer for sun protection.
