These goggles are sweet. They definitely are big, like everyone else has said. They fit very well with a Bern Baker XL Hardhat, and okay with a G10. You definitely need a big face to wear these. I wear a 7 3/8 - 7 1/2 fitted and it seems if my head was any smaller there would be a gap at the nose. For that reason alone is why I gave it 4 stars. So long that you keep the gaps between your face and the foam very limited, there shouldn't be any fogging issues. I love the fact that they come with a hardshell case with vents and a microfiber sack so I dont have to stress over scratching them. The graphics on the Singularity are siiickkk. Im glad they fit well under my bern. Im also stoked that they look so good without a helmet too. Definitely keeping these and if you want some big ol' goggles, I definitely recommend these. I was between these and the Dragon APX. Just based on the price I decided to try the EG2s first. Glad I grabbed these.
