this two-tone swimsuit is perfect for cannonballing, boogie boarding and games of Marco Polo. Plus, it's made from quick-drying nylon, which means he'll stay comfy in and out of the water (aka no sitting around all day in a damp suit), and provides UPF 50 sun protection (think of it as SPF for clothes, although he should still apply sunblock too).
