"TOUGHSUIT" is a long-lasting swimsuit made of polyester material, resistant to chlorine. This series is recommended for swimmers who train frequently. By using high-load fabric, the aim is to strengthen muscles. ■NANO_STRETCH: What is comfortable Nano Stretch created by Descente? With conventional processing technology, the return after stretching was poor, making it far from comfortable. Therefore, Descente focused on the latest nano-level polyester modification technology. It has become possible to create fabric that combines: ● Comfortable stretch ● Excellent kickback ● Soft texture, firmness, and luster Because the fibers themselves are modified, it maintains excellent durability. Unused, with tags, no outer box. I bought it to use at a sports club, but I have no plans to use it, so I am selling it. Please check the images carefully before purchasing.
