Frequently Asked Questions (FAQs)

1. What should boys wear for swimming?

Boys can wear swim trunks or even swim briefs or jammers if they like. Try not to let the swim trunks run too long so that it interferes with their kick. Their trunks should stop just above their knees.

2. What are boys swimming pants called?

Swim trunks, also known as swimming trunks, are a form of swimsuit - clothing worn specifically for swimming. As such, they are usually made of materials specifically designed for being wet and remaining comfortable and hydrodynamic to not impede the swimmer.

3. Why do boys swim trunks have liners?

The main purposes of the mesh liner inside swim trunks are to prevent chafing by creating a barrier between sensitive areas of skin and the trunks; and to provide support to the genitals while swimming, by hugging them close to the body and keeping them out of harm's way during physical activity.

4. Can boys wear swim briefs?

Briefs feature a rounded high-cut leg and were the most popular type of male swimwear in the late 20th century. Swim briefs have a simple design and generally produce the less drag when compared to jammers and trunks. This makes them an excellent choice for young club swimmers or kids in swimming lessons.
