I've used the dragon APX for a couple of seasons now. Decent lenses, fit is good (for me) ,good vision, rarely fog as well. However I will be swapping back to Crowbars next season. Main reason for this is that these frameless goggles seem to have a huge problem skiing in trees and taking bails.
While on conventional goggles if a tree branch hits you in the goggle area, the outerframe will sometimes take most of the hit while on frameless goggles the lens will always take the entire hit. This results in a lot of scratching that could probably be avoided with framed goggles. After a season skiing trees in Japan my apx lenses look like they've been run over by a bus. I haven't fallen bad on my face for a while, but I have noticed new nicks here and there after taking a dive as well.
So if your a skier that never skies trees and never falls on your face, then I can highly recommend the APX!
