I actually bought a size 3 for my 2-year-old because the head openings are always so small plus they were out of size 2.  We can use it again next summer.  Much better quality than swim shirts I bought with tacky logos on the front from big box baby stores.  The colors seems brighter and less likely to fade.  No logos, like I mentioned.

The material is good and thick. It covered my daughter very good and it's a hair big but that's good b/c she can wear it for longer than just 1 summer:)! Great product!
