A beverage cup includes an inner plastic vessel having a bottom, a side wall structure and an upper rim. An insulating rubber foam jacket is bounded to the exterior surface of the bottom and side wall structure of the inner vessel for slowing the temperature change of a beverage contained within the inner vessel. The beverage cup may vary in size, shape, and color. The foam jacket's size and shape are dependent on that of the inner vessel, while its color may vary. The ensemble is manufactured by attaching the rubber foam insulating jacket to the outer surface of the vessel using a dual durometer process which creates a fusion that is much stronger than an adhesive or friction. The integral insulating outer foam jacket reduces the rate of heat transfer between the beverage and the surrounding atmosphere while also providing a smooth, comfortable grasping surface that avoids accumulation of condensation.
