The Island Swim Trunks add a tropical surf-inspired tinge to sun-filled days. Side pockets and a drawcord with reflective detailing at the waist add extra style. But it’s not just for protecting the kids from too much sun. Rapid-dry, chlorine and salt resistant material and a mesh brief make these boys swim trunks great for days of pool play – not to mention practical for parents.
Aqua Plus Lite™ Fabric Our Aqua Plus Lite fabric is a lightweight woven treated with a Durable Water Repellent (DWR) finish so that water beads-up and rolls off the surface. Intelligent features like subtle 4-way stretch and quick-dry make this UPF 50+ fabric ideal for swim trunks and activities on and in the water.
With Coolibar, it's easy to find the UV clothing size that fits your child best. Just use the size charts here and order with confidence every time. To determine the correct size, match your child's measurements to the charts (weight is in pounds and all other measurements are in inches). If you have any questions regarding the fit of an item, talk to one of our Customer Service Representatives at 1-800-926-6509. They will be happy to help.

HOW TO MEASURE YOUR RIGHT SIZE
Use a soft tape measure.
Height: Stand in stocking feet, with feet together, back to the wall. Measure from crown of head to the floor
Arm: Bend arm to 90 degrees. Place hand on hip. Start at center of back of neck measure across the shoulder to the elbow and down to the wrist. Number on inches equals your sleeve length.
Bust/Chest: With the arms relaxed down at sides, measure fullest part of bust/chest, keeping tape parallel to floor.
Hip: Stand with heels together, keeping tape straight and parallel to the floor. Measure around fullest part.
Neck: Measure around base of the neck (the lowest point of the neck). Number of inches equals the neck size.
Inseam: Take a pair of pants that fits you well. Measure from the crotch seam to the bottom of the hem. Number of inches equals inseam length.
Rise: Start the tape at the center back waist, run the tape between your legs, pulling comfortably at the crotch and up your natural waist. Total measurement is your rise.
Waist: Measure around your waist, against your skin (not over your shirt or pants) at the height you normally wear your pants.
Head: Measure around your head, from the center of your forehead, keeping tape straight and parallel to the floor. Measure around fullest part.
All Coolibar fabrics have been approved as an effective UV protectant for covered areas. Coolibar is the first clothing company to receive The Skin Cancer Foundation’s Seal of Recommendation.

Coolibar - Island Swim TrunksBought these adorable shorts for a baby but, unfortunately for the baby's parents, they were too big. I will order again in several months. Very nice quality!

functional and great fitMy son has had other similar products from Coolibar. He needed an additional shirt and bathing trunks for camp. I am just as satisfied with this set as I am with the previous 2 other shirt/trunk combos we bought last year and are still in commission for this summer. you can't go wrong with UPF 50 for the summer at camp. It gives me peace of mind that my child will be well-protected from the sun.

poorly sized and not adjustableThe smallest size does not fit my 5 1/2 year old - it just slides off his hips. (He is average size for a 5 year old.) The drawstring on the front is not functional, just decorative, so can't adjust. Very disappointing.
