Abstract: A device for protecting the arm of a user consists of a protective sleeve and a tubular pouch sized to fit around a user's upper arm. The protective sleeve is made of a preselected protective fabric and is extendible from a retracted position to an extended position for deployment. The protective sleeve is shaped and sized such that in the extended position, the protective sleeve envelops the user's lower arm. An adjustable hand opening at the lower end of the protective sleeve is sized to allow a user's hand to extend out of the protective sleeve. The upper end of the protective sleeve is affixed to an inner portion of the pouch. The tubular pouch is shaped to form a circumferentially extending storage cavity for storing the protective sleeve in a retracted position. This cavity is closed by a closure mechanism when the protective sleeve is stored inside the pouch. The pouch has an attachment mechanism for attaching the pouch to the upper arm portion of the user's shirt.
