I just got back from a rock climbing trip and ended up breaking them... not sure what event may have caused that (so I'll take fault). Though I'm sure a plastic frame would've held up better (though would be worse for the environment, I'm sure). I wore them the rest of the trip with the crack and the lens never popped out so no worries.
I'll probably just glue them back together, no biggie. I like the idea of a bamboo frame better than plastic.
I'll keep rocking them cause they look fly.
