They aren’t smaller you’re thinking of the split jacket.
They do look very similar, but have some weird strap thing around the back. I can’t tell whether that is detachable, and whether the glasses are otherwise identical?
Op, if you can’t find them just click on custom and make your own on the website
Transitions lenses don’t appear to be available as an option on the Oakley custom builder. I’ve found some genuine VR50 lenses for about £50 from a US seller (anyone know of anywhere cheaper?), but the Racing Jackets on the Oakley site start at £180 – I can’t really justify spending £230 on some sunglasses.
I’m ideally trying to find some black Jawbones (or Racing Jackets) for around £100-120, then I can get the replacement VR50s from the US. If anyone knows of any stores that have black Jawbones on sale (doesn’t matter what lenses) then that would be really helpful.
