Good fit for my *almost* 9 yo
Color: Margarita Pink/Vermillion
Cute deign. Proper water protection. Great hold to the string and the clasp. Lenses are very clear and colors are bright and cute. I was kind of worried about the sizing for my almost 9yo, but these sit very well and I think will work for her for quite some time too.. not only size-wise but quality-wise too. These seem well made and durable.

Perfect goggles for girls!
Color: Pink Yarrow/Vermillion
Perfect googles for girls. These do not get stuck in their hair and they are easy to adjust to size. The sun protection is a great added bonus.

Perfect Fit & Great Quality for Kids!
Color: Sky Blue/Celeste
These goggles are amazing for little swimmers! They fit my child perfectly without leaking or slipping, and the adjustable straps make them super easy to customize. The soft seal is comfortable around the eyes, and my kid actually enjoys wearing them , no complaints about water getting in. The lenses are clear and don’t fog up, even after long pool sessions. Great quality from Speedo as always!

so cool!
Color: Mariner Silver/Emerald/Silver, Color: Mariner Silver/Emerald/Silver
so cool!! they were a bit big on my 4 year old, but fit perfectly on my 8 year old! since it was a little wide, the water poured in, but my 8 year old really enjoyed it and they look like sunglasses!! he said they were comfortable and they were so easy to put on and take off, since the straps weren't rubber. the lens scratch a little bit and they don't come with a pouch to keep in. still, great value for the money.

Good seal and cute in photos
Color: Pop Rainbow Sweet Purple, Color: Pop Rainbow Sweet Purple
We had the prior version of these Speedo kids’ goggles and these ones are much better. First, they have the same great no catch string that comes on and off without pulling hair. But they also have a better seal around the eyes, and so after days of hotel pool and swim class swimming we haven’t had a leak yet. The new frames also look a lot more like really cute kids’ sunglasses, so they’re great for all-day hotel pool wear and look great in our holiday photos.
