Aqua SphereKayenne Jr Kids Swim Goggles - Junior Oversized Anti-Scratch Lens Design, Comfortable Allergenic Leak Free Fit | Unisex Children, Clear Lens, Black/Bright Green Frame, EP3010131LC

My husband and I always use Aquasphere goggles when competing in Ironman Triathlons. So we turned to the brand when our three kids decided to join swim team. These goggles are great. They fit well and never leak. They last well. I should have bought tinted ones for the backstroke (hint if you kids are ever on swim team!), but that was my error. These are a high quality product like all of Aquasphere's products.

This has the simplest mechanism for tightening that I have seen on goggles - very easy for my elementary school age child to tighten them. Though it is easy for them to get overtightened. While the loosening tab is also easy to use, it's a bit harder for a child to use than for an adult. As a result, my child sometimes has marks around the eyes from them being a bit too tight. Otherwise, they seal well and my child likes them better than other goggles they have tried.

This is the only pair that works for my 5 year old. Every other model leaks or is simply too big.
