Features This tank top is made of 87% nylon, 12% elastane, and 1% polyester. The fabric is lightweight and stretchy, keeping you comfortable and cool on hot days. The vest features a 3D mesh design. The unique mesh design on the back not only follows the current fashion trend but also improves the ventilation and breathability of the vest. This significantly enhances heat dissipation, keeping the skin dry and comfortable. The sleeveless undershirt has a slim fit that conforms to the wearer's body contours and effectively reduces wind resistance during the ride. This ensures an optimal body posture and high wearing comfort. The minimalist hem provides a pleasant wearing comfort and avoids constriction and discomfort, guaranteeing comfort every time it's worn. This sleeveless garment is easy to care for. Whether it's hand - washed or machine - washed in a laundry bag and dried at a low temperature, it remains as good as new and is durable.
