The Island Swim Trunks add a tropical surf-inspired tinge to sun-filled days. Side pockets and a drawcord with reflective detailing at the waist add extra style. But it’s not just for protecting the kids from too much sun. Rapid-dry, chlorine and salt resistant material and a mesh brief make these boys swim trunks great for days of pool play – not to mention practical for parents.
