It is cute idea but my son is almost 5 and the strap is not long enough to easily fit over his head. When we stretch it to get it over, and then it comes off.
The silicon strap is so helpful to keep our granddaughter's Babiators in place! Its easy to bump the sunglasses while playing in the pool and she is too little to understand how to put them back in place. Now that we have the strap the glasses stay in place at the pool and on the boat!
Just perfect! Perfect fit & totally cool looking. Worth every penny!
The silicone was really soft but the length was too short to fit into our boy's head so he got a little annoyed when putting it on.
If your baby/child pulls on the glasses at all the strap just slips off.
