A winter tracksuit for girls typically includes a matching set designed for warmth and comfort. The jacket is usually insulated with a soft lining, often made from materials like fleece or down, and features a zip closure, a high collar, and sometimes a hood to protect against the cold. The pants are designed to complement the jacket, with elastic or adjustable waistbands for a good fit and sometimes fleece lining for extra warmth. Both pieces are made from durable, moisture-wicking fabrics that help keep the wearer dry and comfortable. They may come in various colors and patterns, such as solids, stripes, or playful prints.
