Frequently Asked Questions (FAQs)

1. 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.

2. What is the point of linings in swim trunks?

When the shorts get wet, the soft mesh lining protects the skin from getting any rash from the wet fabric and makes your time in the water and more importantly out of the water and drying, free of any sort of pain. The net or mesh lining also makes sure your skin is able to breathe by ensuring proper air circulation.

3. Do you need a liner in swim trunks?

Without the lining, the shorts could easily cling to your skin. That's both uncomfortable and difficult to overcome when the fabric is soaking wet. The liner provides an optimal layer of protection that promotes quicker drying time. From a practical perspective, nothing beats the addition of quick-dry swimwear.

4. Do men's swim trunks have a liner?

The mesh lining inside men's swim trunks is designed to cover your noodle and meatballs. It's typically made of polyester, and the itty bitty holes in the netting are relatively small. Some swim trunk designs feature a net that's part of a larger garment lining, while others simply have the net in place.
