Frame: Plasma
Lens: Fire Iridium
As much as I love this combo, it has cracked on me TWICE already. I do not know the reason but it appears the cracks are due to stress put on it at the joint. The cracks are exactly in the same position and similar in shape i.e. two small vertical lines from the nose bridge to the join point of the frame in the middle. Maybe its my face? Who knows...
Frame: Dark Carbide
Lens: Black Iridium
Probably one of my favourite M frame combo. I use it on bright sunny days on the golf course. I also have a Mag M with Fire iridium lens which I use regulary.
Frame:Denim
Lens:Black Iridium
These are tiny. They dont provide much coverage from the sun.
They are also heavy which is the last thing you want if you are wearing them for sport.
Bad idea to make these glasses out of magnesium which makes them unflexible.
If you want an M-Frame I suggest you go with one of the O matter Frames.
The Denim frame is a great colour though
Frame: Plasma
Lens: Fire Hybrid S
Really nifty pair of shades. I eBayed my regular M Frames to partially fund this pair, and it was well worth it. Regular M Frames have a plastic frame which was renowned for snapping, this frame is obviously magnesium but even so just looks much better, thinner and more stylish. It's also very lightweight for a metal frame, a bonus if you do sports. The lens is screwed in so if you fall the lens won't come out, as with regular M Frames. The only downside I might point out is that the range of lens colors isn't quite as wide as with the regular M Frames (and the two aren't compatible), but all in all well worth it over the original M Frames.
