How To Know 1st Generation Vs 2nd Generation?

Mine is XX-XXX 55O21

Is that 5th generation?

Yes. And you can reveal the numbers, it's a model code (aka SKU) not a unique serial

Thanks for the info. As a old school Oakley lover, I hade the pilot grips on my BMX and was given a set of factory pilot glasses after a road bicycle race way back when, it is great to learn so much stuff here. You guys rock.

First Gen or Second.
