Take your goggles to the shop and try them on with the helmet. If you plan on wearing a beanie or anything underneath bring that too, but goggle fit is def most important(besides fitting your head obv)
If your goggles are too big they will either push the helmet towards the top of your head which makes the helmet unsafe not to mention uncomfortable. Or it will put a lot of pressure on your nose which sucks ass too.
I got the Red Hi-Fi, partly because I have anon goggs that are designed to fit it but also cuz it was comfy and light
