The 2-in-1 design features a built-in compression boxer brief liner that's super soft and comfortable - no more itchy mesh that drives kids crazy! The smooth polyester fabric is lightweight, breathable, and quick-drying, plus it has UPF 50+ to block 90% of the sun's harmful UV rays. The elasticated waistband with adjustable drawstring ensures a secure fit that won't slip off during all the splashing and playing. Bright, vibrant cartoon patterns in fun designs that kids love make these trunks stand out at the beach or pool. The 4-way stretch fabric allows complete freedom of movement whether they're swimming, surfing, playing beach sports, or just running around. Side pockets are perfect for storing little treasures too! Available in sizes from 4T through 14 years - just check the size chart to find the perfect fit.
