A sleeve is provided with an antibacterial substance to substantially prevent germs from surviving thereon. The sleeve is designed to be worn by children over their existing clothes, worn over the elbow so that the wearer may cough or sneeze into it with the antibacterial substance acting to eliminate any germs transferred from the wearer to the sleeve by that cough or sneeze. The sleeve is elastic and held in place by a frictional fit that allows for easy application and removal without limiting range of motion for the user.
