Whether it's at the beach, in the pool, or around a sprinkler, most boys adore making a splash. A good boys' swimsuit can help keep your child protected and comfortable while he plays. While many boys' swimsuits are made of UV-protective materials, not all are, and it's always a good idea to check before you buy. A swimsuit with a UPF factor of 50 can help protect your little guy from painful burns while he soaks up the sun. For extra sun protection, consider a rash guard with long sleeves and a high neck. When it comes to size, it can be helpful to take a look at user reviews to find out whether your chosen swimsuit runs large, small, or true to size.
