EC Headwear is super good quality for the price, but atleast for the pair I have I've found that the lenses are almost too dark, like only useable for skiing on super sunny days. Not exactly a bad thing though.
My all time favorite glasses are these:
Reason- lens is just about perfect, but the joints that hold the arms are all plastic. So since I only ski in shades, whenever I slam my face and these bad boys take a hit, the arms come right off. But since it's all plastic, you just snap the arms right back in! Lasts a lifetime.
