Just got some Zero 0.6 today. Pretty happy with this purchase. For being released in 1993 blueish Planet X w/ Blue Iridium - 05-207 Came with original box. Planet X w/ +Red Iridium - 05-208 Still looking for this box. stretched Oakley on both sets of earstems. I have been trying to see what the difference was in the Sub Zero versus the Zero 0.6 ? They were on the shelves of SGH all at the same time too.
