Downgraded for tight fit and lens color.  I've owned 4 pairs of Predator 2s; they fit my large noggin comfortably.  Yes, these were the commercial version of the "Terminator 2" glasses Arnold wore in the movie:  "Predator" for a movie tag, and "2" to tie with that film.  So I've read, going back into the '90s.  The lenses are absolutely NOT glass, but plastic.  The first pair I owned were constructed such that the side pieces made contact with the backs of the lenses when folded, eventually scratching the lenses.  I returned them to Bausch and Lomb, who replaced them with the newer design which does not allow the same problem to occur.  They made the swap free of charge, even though I had  owned the glasses for over 2 years.  My second pair's lenses gradually became scratched in heavy use, and after about 3 years, I returned them to have the lenses replaced.  This was done quickly, but it cost me a bit over $50.  I replaced them after owning them about 5 years when I lost them.  My next pair I likewise owned for several years, and lost them into Niagara Falls.

That brings me to my current pair, purchased in 2017.  These are a bit different.  The fit is a bit tighter than my previous Preds, which causes me to continually have to push them back up on my nose.  Almost sent them back for that.  I do believe it is possible to get them in a slightly larger frame size, but I don't know how exactly.  But the biggest disappointment to me is the lens color.  As you can see above in the description, they should have gray polarized lenses.  Every pair I've owned had gray lenses.  But these came with GREEN lenses.  Again, would have sent them back, but I had ordered them for a lengthy trip and there just wasn't time.  I don't hate the green, but I think  the color rendition of gray lenses is much better than other lens colors; maybe color "neutrality" would be a better term.

Bottom Line:  The next pair I buy will be from Sun Glass Hut or another retailer where I can see and try them on.  There's very little price differential anyway.  BTW, I use these for everything:  beach, flying (pilot), skiing and especially driving.  Polarized good quality sun glasses like these really cut down eye fatigue.
