This is a running wear set from New Balance, featuring a striking contrast of black and green. It's made of lightweight nylon, making it easy to move in and quick-drying. I think it's perfect for running and jogging. Size: M The exterior is nylon and water-repellent. The interior has a mesh fabric, which is breathable and ideal for exercise. I'm selling it because I no longer exercise. Used a few times. I'm not considering lowering the price. new balance Marathon Ekiden (long-distance relay race) Track and Field Baseball Soccer Running Nylon Windbreaker - Brand: new balance - Color: Black/Green - Type: Running Wear Set - Design: Jacket with zipper - Material: Nylon
