Frequently asked questions about boys' swimwear

Do your boys' swim trunks and rashguards provide UV protection?

Yes! Our boys' rashguards and one-piece swimsuits provide UPF 50+ sun protection, blocking over 98% of harmful UV rays. For complete coverage during long sunny days, we recommend pairing boys' swim trunks with a long-sleeve rashguard. It's the perfect combination for beach outings, summer camp, and pool days.

Are your boys' swimsuits chlorine-resistant?

Absolutely! The REPREVE® recycled fabric in our boys' swimwear is engineered to withstand chlorine, salt water, and repeated washes without losing shape or color. Your son can spend the entire summer in the water and his swimsuit will still look great. It's a smart, long-lasting choice for active kids.

How do I pick the right size for my boy's swimwear?

Our boys' swimwear comes in sizes 2 to 14. Use our detailed online size guide to find the ideal fit for your son. If the size doesn't work out, enjoy free returns within 30 days, completely hassle-free. We want shopping for boys' swimwear to be easy and enjoyable.
