New M Frame Replacement Lens
 - 

Hydrid S/Black Iridium
I choose this for its shape and color. For an asian face, I find hybrid S to fit well. The black iridium is perfect for those long hours I spent on week ends on the road with my bike. You can stare ahead on the road without squintting to much.

All throughout university, I was the only one rockin' the Pro M Frames in the lab and machine shop with the clear sweeps. Geeky, but you'd never hear a peep from me about crappy lab goggles pinching my head or causing headaches. 
Definitely the most comfortable and versatile Oakley ever.
