It is a hot summer day, the first thing that comes to anyone's mind is swimming. So what type of costume would you put on before entering the pool?
Nylon is very light in weight and soaks very less water, dries immediately and so it's the best fibre for making swimming costumes. In case if you use cotton, it soaks a large amount of water which makes the costume heavy and it is difficult to swim in that case and it even takes a lot of time to dry up.
