Review on Stay Warm and Agile with Aqua Sphere Stingray Core Warmer by Mike Ken

As mentioned, this is a SPF swimsuit; he does what he claims to do. My son is obsessed with divers and scuba diving and this was one of his favorite birthday gifts this year - he loves pretending to be a real diver. There are two reasons why I gave the product 4 stars instead of 5: A zipper broke and had to be returned. However, this turned out to be a stroke of luck as the size 6 I ordered for my 5 year old son was very comfortable; I would have sent him back immediately if he hadn't begged me! When we sent the one back with the broken zipper, I ordered a size 8; it still barely fits my 5 year old! He's tall for his age, but the size difference is pretty big. I would recommend ordering a size up and paying attention to the zipper. Thanks to Revane for the great customer service though. Not only did they take my return right away and let me order a new product right away, they sent a UPS courier to my home with a tag and all! All I had to do was put it back in the box and hand it to him - by far the most convenient return I've ever had.
