I bought a Cassowary frameset with several different lenses. Primarily, I wanted to use them riding my bicycle. But I also thought they'd be really good for general chores around our farm like mowing on the tractor or zero-turn. Turns out, they're excellent for all of the above. The fit is perfect. Coverage is spot-on. They weigh nothing and fit under the earcups of my hearing protectors just like they fit under the earphones in my flight helmet. I am extremely happy with them!
They are very light weight. Which allows them to sit comfortably while you have your helmet on. I have the transition lenses. While I would like for them to get a little darker. I really appreciate how clear they are while riding when the sun sets.
I love wearing these glasses while cycling. They are light and protect my eyes well. The arms fit nicely under my helmet straps and conform well to the side of my head.
The interchangeable lenses mean that they provide good protection from the wind and flies in all conditions.
The nose supports also do a good job of fitting nicely to my face so they stay in place. At first I was worried they would slide, but they held well even for a century ride in 80F weather.
