Lightweight, sustainable and cool design! Love them!
Can't really think of a pro. It's not more fragile than plastic (even better resistance)
I'm amazed by this product from the very beginning. They are not like the ordinary plastic stuff sunglasses, but made out of bamboo which gives the glasses a new level of high quality. The polarization is great! Also, being a victim of drowned expensive sunglasses, I really like the fact that they float :)
