Frequently Asked Questions (FAQs)

1. Is polyester good for swim trunks?

Polyester is a good material for swim trunks because it's soft, sturdy, and wrinkle-resistant. It dries quickly and retains its shape even after repeated exposure to chlorine and UV rays. Many polyester swim trunks offer UPF 50 for covered areas.

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. What is the best fabric for boardshorts?

First of all, the type of fabric you are probably looking for is polyester microfiber. This is the swim trunks fabric you'll find in board shorts at the store. It is quick drying and soft to the touch, kind of like a brushed twill, except it doesn't hold as much water for as long as twill.
