Honestly, I'm not sure. We had an issue, you solved it, and did so very quickly. We really appreciate that. OH! I know. Have you ever considered larger goggles, much like a SCUBA mask? I buy your goggles for my son but need some for me. After years of competitive swimming, I developed an odd form of claustrophobia. The only way I can swim laps is with my large SCUBA mask. It makes it feel like I can see more around me. It's hard to explain but it gets me back in the water. My mask is old and I need a new one dedicated to laps. No worries if you've not considered this. I figured it was worth a shot. Thanks so much for your help with my son's goggles. He just loves them.
