Men and women have started wearing swimming suits with swim trunks built in, called jammers. These swim trunks cover the upper leg, from the hip to just above the knee. The idea behind them is similar to basketball players wearing spandex shorts under their uniform.
Jammers keep your muscles a little warmer but keep the muscle fibers closer together, and you will get better performance for a longer period of time. In the pool, these swim trunks also create a surface that water rolls off of even better than skin. You swim faster.
*These suits can be half or full suits for men, like regular shorts, or they can go over the shoulder like women's swim suits.
