A single bag therapeutic wrap for applying compressive thermotherapy and cryotherapy to the body, comprising the combination of:

• a casing of flexible material for holding a quantity of a therapeutic medium and having two opposite sheets joined together by a peripheral heat seal defining an internal compartment between opposing inner surfaces;
• releasable fastener means carried on one of said sheets of said casing for achieving a fastened condition;
• said sheet other than said fastener means carried sheet having an exterior surface adapted for conduction of the temperature of said medium to a localized area of the user;
• said casing includes an elongated continuous and tortuous passageway between its opposite ends extending about a plurality of integral barriers defining said passageway;
• said barriers defined as heat-sealed spots joining the opposing inner surfaces of said sheets;
• said casing composed of applicable material having a closable inlet port for introducing said medium into said internal compartment;
• said casing further composed of a fabric material conducting temperature from said liquid medium;
• said fastener means includes at least two straps carried across the major length of said casing sheet in parallel spaced-part relationship separated by the central longitudinal axis extending along said casing;
• closure means cooperatively carried on opposite ends of said straps for effecting releasable closure;
• said closure means is a hook and pile closure;
