This replaces my non MIPS Troy lee design A1 in M/L. So I went with M/L with this guy and the fit is perfect. I tried on a couple mips helmets in the past but really didn't like the feel of the liner. This is the perfect remedy to that. Has a standard liner with the same protection of MIPS. Marketing or not, I'll spend a few extra bucks to potentially prevent damage to my brain. I also like the Kevlar layer to protect from penetration. Fit and finish is good, and to be honest POC wasn't even on my radar I was looking to get a Smith forefront 2 until I stumbled upon this one. I ride with non cycling specific sunglasses and have zero issues with clearance (Oakley holbrooks, and Smith Outlier Xl's). Can't comment on goggle usage, it has a back strap to hold them, but I doubt the visor when fully raised has enough clearance to store them. Overall love the helmet.
