Boys' UV-protective swim trunks: a close fit for swimming
Boys' UV-protective swim trunks offer a streamlined, close-fitting cut for children who prefer a snug fit in the water. At Canopea, our swim bottoms combine comfort, careful finishing and high UPF 50+ fabric protection on covered areas. Paired with a swim top or worn alone, they bring an elegant, timeless look to pool sessions and beach days.
Comfortable swim trunks that stay in place
The close cut avoids excess fabric around the thighs while providing secure support. Made from ECONYL®, a 100% regenerated fibre produced from recycled fishing nets, our swim trunks are soft, lightweight, stretchy and resistant to chlorine and sea salt.
To choose the right fit:
- Consult our size guide using your child's height.
- Check that the elasticated waistband stays in place without marking the skin or squeezing the thighs when your child sits or squats.
UPF 50+ protection and versatile outfits
All our designs provide a physical barrier that blocks more than 98% of UVA and UVB rays on areas covered by the fabric. As fitted swim trunks cover only the hips and upper thighs, remember sunscreen on exposed areas such as the face, legs and arms.
For more upper-body coverage, pair them with one of our boys' UV-protective swim tops or discover our children's UV-protective swim tops.
Fitted swim trunks or shorts: choose for the activity
While fitted swim trunks offer a close cut suited to active swimming and often required in public pools, boys' UV-protective swim shorts provide a looser, more relaxed shape for the beach. Discover the complete range in our boys' swimwear collection.
Frequently asked questions about boys' UV-protective swim trunks
How can I make sure boys' swim trunks are not too tight?
Compare your child's waist measurement and height with our size guide. The trunks should stay securely in place without squeezing the stomach or thighs, even during movement.
Can a UV-protective swim top be worn with fitted swim trunks?
Yes. This combination covers the torso, back and arms while keeping a streamlined fit on the lower body.
How should I care for ECONYL® swim trunks?
Rinse them in cool fresh water after every swim, machine wash on a delicate cycle at no more than 30°C and lay them flat to dry in the shade to preserve the fibre and colours.
