Hey parents! These UPTRIS swim trunks are exactly what your active boys need for summer fun. Made from a super stretchy 50% Polyester + 50% Elastomultiester blend with a 100% polyester mesh lining, these shorts are seriously comfortable and move with your kids. The quick-dry fabric means they won't stay wet and soggy for long - usually drying in just a few minutes after swimming. The elastic waistband with adjustable drawstring ensures a perfect fit that grows with your child, while the two side pockets are perfect for storing little treasures found at the beach. The adorable jellyfish pattern is vibrant and fun, making these shorts stand out from boring solid colors. They're designed to hit above the knee for maximum movement whether your kids are swimming, surfing, playing baseball, or just running around the backyard. With UPF 50+ sun protection and fade resistance, these trunks will last through multiple seasons of pool parties, beach vacations, and water park adventures. Available in eight sizes for ages 2-10, you'll find the perfect fit for your little swimmer. These make awesome birthday gifts or just a fun surprise to kick off summer vacation!
