I have been so good lately. I haven't bought a pair in months. And yet I couldn't help but buy these. the sad thing is I'm still recognized when I walk in the store. Apparently I subsidized the local Vault last year. ;-) In any event, I am not entirely sure what these Fast Jackets are, but the Vault threw in the Jade Iridium lenses along with the engraved black iridium ones. The jade are AWESOME in this pair. I suspect they are a Japan only release. All I know is these are my official Easter sunglasses this year. No box, but that's really ok. I'm happy.
