When I purchased these sunglasses for my daughter is was unaware that they are not covered by Babiators guarantee. It was this guarantee that made me feel comfortable springing for the polarized version! 11 year olds are really good at breaking or losing things. I now went to their website and see it now at the very bottom. I’m not sure sure when they put that there but I didn’t see it when I was shopping initially! I could have missed it. In any case she loves the look and feel of her very fancy sunglasses. Here’s hoping they last.
