try POC Lobes. they have a huge field of vison.
Not so big. Smith prodigy is better, so is Uvex Racer.
I have the Prodigy and they're big alright- however the Smith I/O is bigger. Also the POC lobes are huge too.
Biggest? Try the UVEX S-8500. Works with a helmet (OK, hardhat). Fits over goggles and a respirator too.
