I have bought the boys (21/2 & 4) many different sunglasses and these are the only ones left standing. My Mr destructo has popped the lens out of one but was easy fix- however he hasn't broken the arms like he has others I bought. Plus these seem to be more comfy then plastic ones. Buy these off season on sale. Careful there are 2 sizes-infant & toddler size. We have owned both and they are both great.  Everyone wil be in toddler size  this summer.
