An elastic bandage, also known as a compression bandage or elastic wrap, is a flexible bandage made from elastic material such as cotton or polyester. It is commonly used to provide support and compression to injured or weak muscles, joints, or soft tissues. Elastic bandages are often used in first aid and sports medicine to help reduce swelling, stabilize injuries, and promote healing. They are wrapped around the affected area snugly but not too tightly to provide compression without cutting off circulation.
