the lens of the crowbar is functionally the best part of the goggle. everything looks incredibly clear because of the HDO optics, and they snap in and out with ease for lens-switching. I personally use the fire iridium and HI yellow for bright and cloudy days respectively. I used to have a black iridium lens too that was great for bright days. I recommend the crowbar and all its lenses 100%.
another sick lens that dogfunk does not carry (or is out of stock) is the ruby clear lens. It looks like a regular clear lens from the inside, but has a red mirror on the outside. Sweet!
