If you wear a bathing suit to soak in a hot spring sauna, it will definitely disperse soon, and exposure to high temperature is not acceptable.

I'm wearing SPEEDO Endurance+,which is thick and not easy to deform when I pull it. It is said that this fabric has many functions, such as anti-ultraviolet, anti-chlorine, anti-wear, etc., and it is more than three times more durable than ordinary swimsuits (SPEEDO official website said). it wont hurt you to try it

Choose the model according to the figure and the size according to the height. Remember to try it on! I usually choose a smaller size, because the swimsuit is easy to loosen after launching, which may also be your crux.
