Frequently Asked Questions (FAQs)

1. Is nylon or polyester better for swim trunks?

Nylon Swim Trunks Nylon absorbs more water than polyester, so it dries a little more slowly. However, it's slightly stretchier—making it an excellent option for water sports. When it comes to the look, polyester is more matte, while nylon has a shiny finish.

2. Why do boys swim trunks have mesh 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.

3. What is the difference between swim shorts and trunks?

The most important difference between board shorts and swim trunks is that board shorts are longer (coming down to the knee or below, depending on style & preference) and trunks are shorter (stopping above the knee).

4. Do all men's swim trunks have netting?

Not all swim trunks come equipped with netting. Board short-style swim trunks, which are cut closer to the body, typically do not. Try on swimwear to ensure a good fit; swim trunk netting that is too tight can cause pain in the groin and netting that is too loose provides little or no support.
