Zusammenfassung:	A flexible heat transfer device 1 for heating or cooling a surface such as the skin has an envelope 2 formed from two double walled sheets 3 and 4. Each sheet contains within the double wall a first high thermal capacity material 11 such as a freezing gel that is flexible when frozen for good surface contact. The space 13 between the double walls contains a second high thermal capacity material 12 that may have different physical properties than the first material. This may be in the form of a removable pouch insert 24 that may be heated or cooled separately. The device is more versatile in its applications and provides for more prolonged heating and cooling.
