I just got my original MARS glasses repaired by X-Man, the bridge was very loose. He repaired the bridge and blasted the frame, they look like a brand new pair of glasses. I will post a picture when i get the new lenses
My Zeros, i have only worn them a few times, i purchased them about a month before my first pair or MARS glasses. They were on sale and i got them for under $100, Which for Oakleys here in OZ is pretty cheap. I only really wear them when i go for runs or workout outdoors. they are a fair bit lighter then the MARS glasses.
