A protective cover is comprised of a flexible material, such as natural latex, and may be colored or may include a design. A hole may be included for inserting a straw or as a drinking spout, and the hole may be reinforced. The protective cover may be comprised of a central circular portion and a circumferential side portion and may be sized for fitting bar glasses. An edge on the side portion may be formed by folding the edge over itself and adhering the folded layers together, providing a resilient elastic band for retaining the protective cover on a glass.
