What are the requirements for the selection of swimsuits?

Men's swimsuits, mostly cotton, wool or chemical fiber fabrics, are triangle shorts, monochrome or with various patterns. The rules of swimming trunks for competitions stipulate that they must be dark, and the crotch length on both sides should not be less than 10 cm.

(3) Resistance swimsuit

Special clothing for swimming training. The appearance is the same as that of an ordinary bathing suit, except that several pockets are added at the front and back of the suit, with the pockets facing upwards, for practicing paddling, fetching water or swimming together. When a swimmer swims forward, filling his pocket with water can increase the resistance, thus enhancing the muscle strength of all parts of his body.
