The lenses that came with my half jackets (fire) were pretty good, but I wanted something that was a little truer to color as well as darker. The Black Iridium lenses have done the trick. They work great on just about any light, even reflecting light off of water. As a side note, these lenses make colors more rich especially the sky which made my trip to Arches NP even better.
I have had these glasses for 4 months now and they are great. I love the interchangeable lenses and would suggest getting the black iridium lenses, I haven't taken them out since I slapped them in. I use these glasses for everything from driving to hiking to kayaking and they never have come loose or fallen off my face. There is only one drawback. They will not be making polarized lenses for these any times soon, but the Black Iridium lenses do just as good as some of my buddies polarized lenses.
