Sweatpants are comfortable, loose-fitting trousers typically made from soft materials like cotton or polyester. They are designed for casual wear and are often used for exercise, lounging, or running errands. Sweatpants usually feature an elastic waistband and may have cuffs at the ankles, making them easy to put on and take off. Originally created for athletes, sweatpants have become a popular fashion choice for people of all ages. They come in various styles, colors, and sizes, allowing for personal expression. Many brands, such as Nike and Adidas, offer sweatpants that combine comfort with trendy designs.
