The Young Press was designed to develop a modern yet functional coffee press that delivers top quality coffee and can be used in a variety of environments. The durable frame is made of santoprene - a hard rubber-like material. The windows are made of clear polycarbonate. Together, these two layers form a protective skin around the glass beaker that helps prevent breakage, making the Young Press an ideal press for home, office, boat and even camping. The glass beaker can easily be removed for cleaning and placement in the dishwasher. For those who prefer to hand-wash their Young Press, they don't need to worry as much about knocking the glass beaker against a metal sink. The Young Press' frame also assists in keeping the coffee hot longer while insuring that the body of the press remains cool to the touch and is safe to set on most surfaces.34oz capacity.
