An attachment (302) for a drinking vessel for keeping a drink cool has an elongate bag (312) of flexible film material for containing ice. For attachment to the vessel it may be fast with a lid for the vessel or have a clip (346) for clipping over the vessel's rim. A sealed lower compartment (313) may contain a weight (314). The ice compartment (318) may have an access opening closable, e.g. by means of a lid or engagement elements (342, 344) on opposed inner face portions of the bag or by a resilient band.
