Sports bras usually use soft and comfortable fabrics, such as cotton and linen, which have strong skin-friendly effect and are easily absorbed after sweating. Swimsuit is generally made of nylon, which is often called nylon fabric. This fabric doesn't absorb water, but it dries easily. After swimming in it, the clothes will dry quickly, but the sports bra will not work.

2. Different functions

Although sports bras and swimsuits are both used for sports, their functions are completely different. Sports bra is used to protect the chest when we do all kinds of sports. It has the functions of shockproof, sweat absorption, deodorization and ventilation. The function of swimsuit is waterproof and quick-drying, but it does not have the function of shock prevention.

3. Different usage scenarios

We can use sports bras in various scenes such as running, dancing, yoga, fitness and so on, which can avoid underwear from affecting our movements. Swimsuit is only suitable for us to wear when we go swimming, and the application scene is simpler.
