UPF 50+ Baby Boy Swimsuits & Accessories

A big beach vacay or just a kiddie pool in the yard, Carter’s and OshKosh baby swimsuits are made to make the most of your boy’s first splashes. And the best part? UPF 50+ sun protection is built in — it’s in the sun and swim hats, too.

Comfy New Styles, Always Easy Features

Suit them up in bright, sibling-matching signature prints for the perfect poolside matching moment. With quick-drying fabrics, easy snaps and even full-zip rashguards for baby, on and off is easier than ever.

As he learns to love the water, your number one goal will be keeping him safe in the sand, sun, and surf. We’ve crafted our ​​baby boy swimwear with the same goal in mind. Our swimwear is made with built-in UPF 50+ sun protection. Comfortable materials and designs eliminate any bulkiness, so he can float in safety. To see this season’s styles, shop baby boy new arrivals. Don’t forget to add functional baby boy accessories, like baby boy sunglasses for eye protection and water-ready baby boy shoes for foot protection.

Cool and Classic Swim Trunks 

Classic beach and pool wear for boys would be swim trunks. This type of baby boy shorts is made from materials meant to get wet. A shorter inseam and elastic waist make for a perfect fit that won’t get in his way of exploring the water or the shore around it. We carry solid, stylish colors and graphics inspired by the sea and island life. From sharks and whales to stripes and surfboards, our collection is never boring.

Ease Into Swim Sets 

Take the guesswork out of swimwear shopping and opt for a ready-made set. These sets come with swim trunks and a rashguard shirt that coordinates. We offer both short-sleeve and long-sleeve top options in different designs. Sets look like a well-paired outfit, so he can wear them around all day. And since they’re made to get wet and dry quickly, he’ll always be comfortable.

Surf’s Up in 1-Piece Rashguards 

Inspired by the suits divers and surfers sometimes wear, these 1-piece rashguards give him more protection than classic swim trunks. His top half will be protected from the sun and any other irritants. With short-sleeve and long-sleeve options available in a variety of cool designs, you can choose the right fit for your lifestyle.
