I have a chance to buy some "limited Editions" Oakley Frogskins from an Oakley Vault store, but i don't know how limited they are. I am looking at the GP-75 or some from the Summit Collection but i have no idea what to buy. Oakley says things are Limited or special editions but they never say how many are made. i just bought the Distressed Blue Radar Path and some limited addition Matte Carbon Fiber RadarLock. They only had a couple of them at the store and i bought them thinking that they would be an one of the kind pair that not many people had, but are they or are they not "limited"
