Question: My main concern is "not leaking".  I've tried many googles and the chlorine finds a way to get inside.  How good is this feature?  Thank you.
Document: Got these for my soon to be 5 year old once he became considered &#34;water safe&#34; at swim school and graduated to a swim class where he would be allowed to use googles. They were selling them at the school so purchased there... He used them so much that we bought a 2nd pair through Amazon at a better price! These work great and we have friends who now want to purchase because their &#34;novelty or character&#34; once are not working as good ; ) I actually got an adult size for myself to use when we are in the pool but yet to try them out.
