Bought these along with the Rukus, wasn't sure which pair I would like better. Chose the Rukus, better fit for my face. Sold these to my buddy who loves them. Good value and can be used as a goggle as well as glasses.
I've been using transition lens riding glasses for a few years now and I do not see going back to interchangeable any time soon. I like having this style foam because its not too thick or obtrusive and the idea of it being removable is a plus for when you are walking around off the bike. Upon receiving the glasses I immediately notice just how thick the removable portion was. I find they hinder my peripheral vision much like blinders on a hoarse. I sent them back for a different set. A+ for Dennis Kirk customer support!!
