Hey guys! I love my black Flak Jackets, but I'm beginning to think that all black is a little... boring? Im looking to make the glasses more interesting, maybe by buying a new lens color. I currently have the standard black. What color do yall think? Also, the arms of my Flak Jackets are really loose now. Is there any way to bring that 'snap' they had when they were new back? Or at least tighten them? Thanks yall!
