Laundry bags are containers used to hold dirty clothes before washing. They come in various sizes, materials, and designs, making it easy to sort and transport laundry. Common materials include cotton, polyester, and mesh, which allow for breathability and easy cleaning. These bags often feature drawstrings or zippers for secure closure, preventing items from spilling out. Some laundry bags are designed for specific purposes, such as delicates or sports gear, while others are simply for general use. They help keep laundry organized and can be used at home or while traveling.
