Find the right swim and surf shorts for kids who love to move. Learn about fit, features, and when to choose board shorts over snug trunks.
Quick answer
For active kids who run, swim, and boogie board, choose board shorts with an elastic waist and built-in undies for easy changes, or snug trunks if your child dislikes flapping fabric.
Board shorts vs. snug trunks: what's the difference?
Board shorts (like the melting masks surf shorts) have a classic surfer's cut—roomy through the leg and hip—so kids can move freely without restriction. They typically include built-in underwear and an elastic waist, making them easy for a child to pull on and off alone. Snug trunks (like the solid swim shorts) have a trimmer, '70s rock-and-roll silhouette that fits close to the body. They're ideal for children who find loose fabric distracting or uncomfortable in the water.
What about quick-dry fabric?
All swim shorts are designed to dry faster than cotton shorts, but the cut matters more than a special coating. Roomy board shorts can trap more water and feel heavier when wet, while snug trunks shed water faster because less fabric is touching the skin. If your child will be out of the water for long stretches (like a beach day with lunch breaks), the trimmer fit helps them feel dry sooner.
How to decide: 3 quick rules
- 1. Check the waist and closure: Look for an elastic waistband (no buttons or zippers) so your child can dress themselves. Built-in underwear is a bonus for quick changes. If your child is still learning to dress, elastic waist is non-negotiable.
- 2. Match the fit to the activity: Choose board shorts for running, swimming, and boogie boarding—the roomy cut won't restrict movement. Choose snug trunks for calmer water play or if your child prefers a close fit. Consider asking your child: do you like shorts that flap around, or ones that stay close to your legs?
- 3. Consider drying time: Snug trunks dry faster because there's less fabric. Board shorts take longer but offer more coverage. If you're packing for a day out, bring a spare pair or pick the trimmer option. For long beach days, a second pair of swim shorts can be a lifesaver.
