This is a Nike running cap. The color is black, and it's reversible with a pattern. It has Dri-FIT, a moisture-wicking and quick-drying function, so you can stay comfortable even during exercise. It's perfect for sports and outdoor activities. It's a reversible design that can be used on both sides. It's in a still-beautiful condition as it has been used very little after being purchased new, but the edge of the Swoosh on the patterned side is slightly peeling (see image 2). Size: Depth: 19cm Head circumference: 54cm, but it has elasticity and can stretch to over 60cm. Thank you.
