Great goggle, comfortable, vents easy and fits inside of my helmet without issue. Lens is swapped out using the same Oakley changing method; pull real hard and fight it back in. I have a mirrored emerald lens and the high intensity yellow lens and haven't changed the lens out much, the emerald lens seems to work in most conditions. The cons? They are HUGE! I have scratched the lens with my board or hitting the goggles on something while on top of my helmet because they stick out so much... but thats what replacement lenses are for!
