I have likely got 10 helmets if have tried every combo you could ever think of, used to wear a open face with a flip up shield and duct tape face mask to my face was good till stopped for lunch lol. This is SnoWest i will assume you are not trail riding, you will be riding in altitude and working hard creating body heat and breathing hard. I can ride with any helmet but most any full face or modular is very restrictive on your breathing when working hard and yes that's getting away from the topic of vision. You need to evaluate what kind of rider you are, where you ride whats most important to you. I have a modular with elect for very cold days in the Prairies say morning temp -28C and maybe warm up to -21 can still be a great ride if have the correct gear. But if going to be warmer than -20 C (-28.8F) it is Moto and Goggles as can see and breath easy. my2c
