The Best Long-Sleeve Swimsuits for Girls

Buying Guide for Long-Sleeve Swimsuits for Girls

Why buy a long-sleeve swimsuit for girls?

Sun protection is important to start young. Long-sleeve swimsuits are a great alternative to traditional swimsuits because they cover the skin to protect it from UV rays as well as potential scrapes on paddle boards or surfboards. They’re a fantastic option for kids with extra-sensitive skin, too.

What should you consider in a long-sleeve swimsuit for girls?

  • UV Protection: All sleeved suits will offer some protection from the sun, but some materials are better than others. Some can offer UPF 50+ skin protection, which is great. Just know that these materials may have specific wash instructions, so read the care tag thoroughly before washing a new swimsuit.
  • Patterns and Colors: What girl doesn’t love to express herself? There are so many bright, colorful selections in long-sleeve swimsuits. Whether your child prefers something simple or wants to be a real-life mermaid with an added flowing skirt, your child can show off her unique sense of style in the many options available.
  • Coverage: Some long-sleeve swimsuits cover the arms but leave more of the back and legs exposed to the sun. Others cover more, including the tops of the legs and the whole back and neck. While some children love the feeling of full coverage in their suits, others like the freedom of having some skin exposed to dry off faster and potentially stay cooler. You can find the right level of coverage for your child with the range of options available.

Why is a long-sleeve swimsuit called a rash guard?

The term “rash guard” was used in Australia to define a long-sleeve swimsuit. It’s called a rash guard because it’s made to protect the skin against sunburn or a rash from skin rubbing on the sand. If your child is particularly active or plays water sports, a rash guard will help protect against abrasion.
