Boys’ Size Guide
Find your son’s Laino trunk size. For babies and toddlers, start with height and weight, then check the measurements below. Waist is the key measurement; length and inseam describe the cut. If he is between sizes, we recommend sizing up.

How to Measure
Waist: Around where the trunk sits, at the natural waist. This is the main fit measurement.
Length: From the waistband to the hem, for how long you want the short to sit.
Inseam: Along the inner leg, from the crotch seam to the hem.
- For babies and toddlers, use height and weight first. Age is only a starting point.
- Adjustable drawstring and quick-dry fabric with UPF 50+ sun protection.
- If he is between sizes, size up for a little more room to grow.
- Matching Dad? Order his trunks in the same print to complete the set.
