Let me start by saying that I am a human heater - my wife loves me for it. but, it also means that I sweat and fog glasses like mad! Enter the Oakley jawbreaker - best vented, most comfortable and least fogging glasses I have ever owned. 

I already thought I had the best glasses with the trail lenses but today I got the photochromic - whoa momma! I was going in and out of heavy canopy in to bright sunlight and I never even noticed that I was wearing them, except when I wasn't getting bugs in my eyes.

Very happy :)
