Honestly, these sunglasses are solid. The arms bend nicely without feeling flimsy, and I love that you can adjust the nose pieces to get them just right—no worries about breaking anything. They feel really well-made.
The polarized lenses cut glare like a champ, which is awesome for driving. Only thing is the sun still sneaks in from the top a bit, but throw on a hat and you're golden. That combo works perfectly for me.
