Swimsuit comes with underwear, so you should exercise in the water when you go swimming. Wearing too much will also affect our sports. Moreover, swimsuits are generally made of DuPont Lycra, nylon or polyester fabrics, which do not sag or swell when exposed to water, and are thick, crisp and impervious, with good elasticity, softness and firmness.
If underwear is worn in a swimsuit, because the shape of swimsuit and underwear is different, underwear will definitely be exposed, but it will be more eye-catching and awkward. In addition, underwear is thin, penetrating and close-fitting, unlike swimsuits, which dry quickly. Wet underwear can be very uncomfortable and may even be harmful to health.
Should I wear underwear in my swimming trunks?
If underwear is worn in a tight-fitting swimsuit, because the shape and style of swimsuit and underwear are different, they can't overlap well, which may lead to the underwear being "squeezed" out, which is very difficult. Moreover, underwear is mostly close-fitting and the fabric is thin, so it is soaked, which affects the comfort. It will be very uncomfortable to wrap the soaked underwear in tight-fitting swimming trunks.
But if it's a loose swimsuit, you have to wear underwear. Because loose swimsuits can't fit the body well, bacteria in the water will inevitably be brought into the body when swimming, especially breaststroke, while loose swimsuits such as boxers don't have to worry about underwear leaking out, which can prevent bacteria from entering to some extent.
