well besides telling u searchbar i will sum it up in abt 2 sentences, difference between crowbar J and regular crowbar is that there is a little difference in the nose piece, honestly not that big of a difference so they should fit u fine
people will tell you to use searchbar which you should have but ill say it nicely cause everyone was an ass about it to me when I was a super noob. But ya theyll be fine the foam is the only thing different. right around the nose. It wont affect a thing man.
The J Crowbar essentially is a normal crowbar that has extra nose foam padding (roughly double the normal amount) to make up for the lack of nose definition. So unless you have a very small nose bridge for a white guy, I'd recommend not because the extra foam will lift the goggle seal from the cheeks and allow air to come up.
