A sports garment needs to be light in weight, non-absorbent of sweat, easier and faster to dry, etc. Cotton absorbs moisture but does not dry easily. Clothes made of synthetic fibres like polyesters and nylon do not absorb moisture. Instead they help in quickly transporting the sweat from the skin to the outer surface, from where it dries off easily.
