at least one second pocket that contains an air-filled chamber associated with air pumping means, at least said first pocket and said flap being made of impermeable and thermally-insulating material.

2. The kit of claim 1, wherein said first pocket and said second pocket substantially mutually overlap.

3. The kit of claim 1, further comprising first sensing and indication means for sensing and indicating a temperature value of said at least one pouch of fluid.

4. The kit of claim 3, comprising first display means for indicating the detected temperature value, said first sensing and indication means comprising a temperature probe, which is arranged inside said first pocket, and a cable for associating the temperature probe with said first display means.

5. The kit of claim 4, further comprising second sensing and indication means for sensing and indicating a pressure value of the air fed into said chamber.

6. The kit of claim 5, comprising second display means for indicating the detected pressure value, said second sensing and indication means comprising a pressure gauge, which is associated with said air-filled chamber and is associated with said second display means.

7. The kit of claim 6, wherein at least one of said first and second display means for indicating the detected value comprises a display and/or a graduated scale and/or acoustic warnings and/or luminous warnings.

8. The kit of claim 7, wherein at least one of said display and said graduated scale is made of a material that is visible in conditions of poor ambient visibility, selected among a fluorescent material, a bright material or a light emitting material.

9. The kit of claim 1, wherein said pumping means comprise a bulb made of an elastic material and a tube that has an end associated with said chamber and an opposite end associated with said bulb.

10. The kit of claim 1, comprising at least one shoulder strap, which is provided with adjusting means for adjusting length thereof and which is associated with said bag.

11. The kit of claim 10, comprising two said shoulder straps.

12. The kit of claim 1, comprising coupling means for coupling to a hanger element, said coupling means being associated with said bag.

13. The kit of claim 12, wherein said coupling means comprises a slot formed at a top region of said bag.

14. The kit of claim 1, comprising closure means that are formed between said flap and said first pocket and/or at end regions of said second pocket.

15. The kit of claim 14, wherein said closure means are selected from a group comprising buttons, press-studs, and tear-open cling strips.

16. The kit of claim 1, wherein said impermeable, thermally-insulating material comprises at least one impermeable layer and at least one thermally-insulating layer.

17. The kit of claim 16, wherein said thermally-insulating layer is made of a material selected in a group comprising Nylon and neoprene.

18. The kit of claim 16, wherein said first pocket comprises a layer of inextensible material that is formed at an outer wall thereof that is directed away from said second pocket.

19. The kit of claim 1, wherein said thermal reactor comprises an enclosure that is closed and divided into at least one first compartment, which contains a first component, and into a second compartment, which contains a second component suitable to react with the first component with an exothermic or endothermic reaction, said second compartment being separated from said first compartment by a tearable membrane, at least one of said first and second compartments, containing respectively the first and second components, substantially in a vacuum ambient.

20. The kit of claim 19, wherein said enclosure comprises insertion means for insertion of a tool for tearing said membrane.

21. The kit of claim 20, wherein said insertion means comprises retention and sealing means for preventing leakage of said first and second components and inflow of the air that lies outside said enclosure.

22. The kit of claim 20, wherein said insertion means further comprises an inlet and said retention and sealing means comprises an insert made of elastic/elastomeric material, which is accommodated in said inlet and is suitable to be crossed by said tool and to close an opening formed therein by said tool.

23. The kit of claim 19, wherein at least one of said first and second components is a loose particle or granule form solid, the other component being in a fluid form.

24. The kit of claim 20, wherein said enclosure comprises a first bag, an interior of which forms said first compartment, and a second bag, walls of which are at least partially constituted by said membrane, said second bag being accommodated inside said first bag, and forming internally said second compartment.

25. The kit of claim 19, wherein said enclosure is made of a material of a flexible type.

26. The kit of claim 19, wherein said enclosure comprises at least one heat-conducting portion.

27. The kit of claim 24, wherein said first and second bags are associated to each other at at least one portion of respective walls thereof.

28. The kit of claim 27, wherein said insertion means are associated at said portion.

29. The kit of claim 1, comprising anchoring means, said thermal reactor being coupled by way of said anchoring means to said pouch of fluid.

30. The kit of claim 26, wherein said enclosure is superimposed on said pouch at least at said heat-conducting portion thereof.

31. The kit of claim 29, wherein said anchoring means are selected in a group comprising straps and adhesive tapes.
