Drawstrings are used in clothing outerwear such as jackets (anoraks, hooded sweatshirts), trousers (breeches, pajamas, scrubs), tracksuits, hats, berets and bags (pouch, sleeping bag, stuff sack, money bag, book bags, back packs, garbage bags), and shoes (as a shoelace). On clothing and bags, an aglet is at the end of a drawstring to prevent unravelling, and a cord lock can be used on a drawstring to keep it taut. A safety pin, bodkin, or crochet hook can be used to pull a drawstring through a hole.
