A cotton arm sling is a comfortable support designed to hold the arm and shoulder in a stable position during recovery from injuries such as fractures, sprains, dislocations, or after surgery.

It typically features an adjustable shoulder strap for a secure fit and a thumb loop or hand support to keep the arm properly aligned. The sling is lightweight, washable, and suitable for both the left and right arm.
