Make a splash all summer long in our Sebastian Swim Shorties. Designed for comfort, movement, and endless water play, these swim trunks feature a playful shark print with bold red trim that stands out poolside or at the beach.

Crafted with a soft, stretchy outer fabric and a built-in brief lining, these shorties offer a secure, comfy fit that keeps up with every cannonball, sandcastle, and swim lesson. The adjustable drawstring waistband makes sizing easy, while the back pocket adds a functional touch for little treasures found along the way.
