The swimsuit is made of ECO C-INFINITY fabric. This fabric is environmentally friendly because it is made from recycled plastic bottles. The swimsuit excels in long-term resistance to chlorine. The material is a 100% polyester that retains its color even in case of long-lasting chlorine and solar radiation. Thanks to the great technology, the swimsuit maintains their strength and is therefore also suitable for daily training of performance swimmers. In addition, the ECO C-INFINITY fabric is well breathable, soft to touch and dries quickly. They are lined with a lining. This is a weaker layer of fabric under the upper fabric. The lining contributes to the durability of the swimsuit and swimsuits are not transparent after soaking. This is especially true for swimwear of lighter and white color. The only disadvantage of the lining is that swimsuits will dry longer. The swimwear have elasticated waistband for better tightening and comfortable wearing. The fastening string guarantees comfort. You can fasten the swimsuit by the string and you don't have to worry anymore that the swimsuit will fall down when you jump in the water.
