Designed for little scientists, this "boys' two-piece set" offers both comfort and a spirit of discovery! The top is made from cotton jersey fabric; its soft texture allows for breathability and freedom of movement all day long. The fun "I'M GENIUS" print reflects the energy and ingenious world of science-loving children. The shorts are made from durable gabardine cotton fabric. They are perfect for adventurous running games, bike rides, and park explorations. The shorts feature a cargo pocket and two side pockets, allowing children to carry their most precious little treasures—stones, leaves, small toys—and collect their adventures!
