Just received these glasses a few days ago (the black gt/ec/ac), and am incredibly pleased with them.  After just a few days with these I've already come back to order the white fototec pair.  Have already played 3 outdoor matches in the black GTs, and they are a huge improvement over my previous glasses.  Which were, admittedly, aviators.  But these are great nonetheless.  Much better visibility, with a uniform field of view- not having to see the frames helps a lot with serving.  Brighter than what I used to use as well, which maybe sounds bad, but I'm not squinting and I have the UV protection, so it just amounts to me being able to see the ball/court/my opponent better.  The nosepiece grips my nose superbly.  Supposedly the ears have the same material, they don't feel quite as grippy.  But they are very snug on my temples, so I have no concerns that they will fall off.  I'm 6'4", with a more or less proportionally sized head.  I'd say they're a little snugger than I'd want if I was buying these for general comfort wearing, but I'm not bothered by it at all while playing.  I prefer having the extra tightness to worrying about them falling off while chasing down a ball.  And the lenses wrap around the eyes nicely with full coverage.  Variable lenses are a wonderful touch and easy to swap out, though the default lenses seem suitable for most days.  The AC lenses for overcast days have the added bonus of making you feel like Janko Tipsaravic, for whatever that's worth to you.  I don't expect to be doing a lot of 'green-reading' with the pink EC lenses, but it's nice to know I could if I wanted to.  Hard case is great if I don't want to worry about scratches, soft case is great if I don't have room for the bulk of the hard case.  Soft case also cleans them very satisfactorily.  Overall, just an exquisitely well thought-out pair/sextet of glasses, I'm astounded at how much they give you for your money.  Thoroughly pleased that companies like Tifosi exist.  I'll probably buy the red ones too if they get them back in stock with the gt lens option.
