Fit and comfort 1. Can't find a light that will fit the mount that comes with the helmet. Strapped on a Lezyne in the back which helps. Fortunately haven't had a fall to test out the MIPS. I use it primarily for road riding an ebike. I broke my neck a couple of years ago riding a bike path with a front tire blowout resulting in a concussion and a broken C2 vertabrae wearing a helmet (not this helmet). Hard to say whether the MIPS system would have helped. Nevertheless I'm pleased with it so far.
