Boys' 4F swim trunks are a practical model for the pool, learning to swim, and water activities. If you're looking for a boy's swim trunk with 4FDry technology, UPF 30+, and chlorine-resistant material, this model is a good choice for regular use.

4FDry technology helps wick away moisture and promotes quick-drying, making it easier to stay comfortable after getting out of the water. The 85% polyester and 15% elastane main fabric provides a flexible fit during movement.

Chlorine-resistant material helps maintain the swimsuit's appearance, shape, and performance for longer. UPF 30+ provides protection from the sun's rays during outdoor activities.

An adjustable waistband with an internal drawstring allows for a snug fit, while the front lining enhances coverage and comfort while swimming. Also check out 4F products and our swimming and pool category.
