A thermal insulating jacket for use around pipes, conduits, tanks and related members according to the present invention includes a flexible outer covering such as a sheet of plastic or polyvinylchloride which has bonded to its surface an alternating series of insulation material strips. The insulation material strips which are bonded to the flexible outer covering include a first plurality of flexible insulation material strips and a second plurality of rigid insulation material strips. These different material strips are arranged in alternating sequence and the combination of outer covering and insulation strips is sufficiently flexible and formable so as to be wrapped into a generally cylindrical shape which may then be disposed around a pipe, conduit, tank or related member, for thermally insulating that member. The outer covering may be a one-piece member or a hinged member.
