These swim trunks are crafted in a swimsuit-friendly cotton oxford/nylon blend for a clean, classic look. An elastic waist makes them easy to slip on and off (so he can dress himself), and there's a neon drawstring to keep the trunks securely in place. We also added a full mesh-brief lining for comfort and the cutest patch pocket in the back. The genius thing? If you get desperate (that is, if you're not doing laundry anytime soon), you can totally pass these off as regular shorts.
