First and foremost, what is a swimming trunk net? The crotch area is covered by the netting lining inside swim trunks. The netting is usually composed of polyester, and the holes in the netting are tiny.
Some swimmers just find it bothersome or feel chafing as a result. As a result, it's better to attempt swim trunks without netting or to clip the netting out yourself.
The major function of the net within a pair of swim trunks is to give genital support when swimming. In a similar way as brief-style underwear, the netting wraps the genitals close to the body. This keeps them out of harm's way while exercising.
To promote air circulation and ensure that the sections covered by the net do not stay moist, netting is utilized instead of a solid cloth. Netting also creates a more even line beneath the swimsuit.
