these are super great. i have a helmet and i wear them around it. fit great. Also the frame is not rigid. it is "flexible" so it fits to your face really comfortably. dont be scared about the flexy part, they are just like all other goggles, just better! no fogging yet and ihave been riding with them for 14 days so far, from fresh pow and comfy temps to frigid weathers. get some!
