80.0% Polyamide, 20.0% Elastane. Very comfortable and soft with excellent stretch properties Chlorinated water can be harmful to swimsuits which are used repeatedly in the swimming pool. The elastane fibre that gives the material its stretch properties and therefore makes it comfortable is also fragile when in contact with chlorine. If you swim occasionally this material will be fine for you, otherwise opt for a 100% polyester material.A swimming swimsuit should primarily favour comfort. It should enable you to move with ease. That is why it is important to choose the shape of your swimwear carefully. The swimsuit provides great muscle compression for the quads and glutes, resulting in the perfect fit.
