Long sleeve zipper swimsuit. So easy to put on and take off. Best baby swimsuit! Made of highest-rated, most comfortable UPF 50+ sun protective fabric. Blocks 98% of UVA/UVB rays. 4-way stretch for freedom of movement. Quick-drying and chlorine resistant. My baby only wore this twice, there is a small discoloration on the sleece (pictured) not sure if this would come out in the wash but definitely doesn't effect function!
