When it’s time to hit the beach, he will need the right boys’ swimwear. If he’s simply into having fun in the sun, boardshorts and swim trunks are always popular choices. (Just be sure to add sunscreen and a hat.) Budding Olympic swimmers and boys with very sensitive skin will probably prefer a rash vest. The most important thing is that kids’ swimwear, be it boardshorts, trunks or a rash vest, should fit comfortably and properly – two- to eight-year-olds just want to have fun!
