The heat retaining article according to the invention comprises at least one inflatable envelope attached on a sheet material. The envelope is made of an air-impermeable sheet which is produced by treating a cloth with at least one synthetic or natural rubber. The heat retaining property of the article can be controlled by adjusting the amount of air filled in the envelope.

1. A heat retaining article comprising at least one inflatable envelope attached to a sheet material, said envelope being made of an air-impermeable sheet consisting of a cloth treated with at least one synthetic or natural rubber, said envelope containing a wadding material consisting of at least two polymers having different melting points, one of said polymers having been melted to partially weld said wadding, thereby substantially preventing said wadding from moving about within said envelope, the heat retaining property of said article being controlled by adjusting the amount of air in said envelope. 2. The heat retaining article according to claim 1, wherein the density of said wadding material is from 0.001 to 0.05 g/cm 3 based on the volume of the inflated envelope. 3. The heat retaining article according to claim 1, wherein said envelope is tubular. 4. The heat retaining article according to claim 3, wherein said tubular envelope has a diameter of from 5 to 500 mm. 5. The heat retaining article according to claim 1, wherein said envelope is divided into plural air chambers connected to each other. 6. The heat retaining article according to claim 1, wherein said envelope is attached to said sheet material such that, when said envelope is filled with air, a portion of said envelope which does not face said sheet material is inflated and projects away from said sheet material but the portion of said envelope which does face said sheet material is substantially plain. 7. The heat retaining article according to claim 1, wherein said article is a tent, a sleeping bag, boots, a bag, a portable ice box or an article of clothing. 8. The heat retaining article according to claim 1, wherein said wadding material comprises conjugate fibers. 9. A heat retaining article of clothing comprising at least one tubular envelope attached to a sheet material, said envelope being made of an air-impermeable sheet consisting of a cloth treated with at least one synthetic or natural rubber, said envelope containing a wadding material consisting of at least two polymers having different melting points, one of said polymers having been melted to partially weld said wadding, thereby substantially preventing said wadding from moving about within said envelope, the heat retaining property of said article of clothing being controlled by adjusting the amount of air in said envelope. 10. The heat retaining article of clothing according to claim 9, wherein the density of said wadding material is from 0.011 to 0.05 g/cm 3 based on the volume of the inflated envelope. 11. The heat retaining article of clothing according to claim 9, wherein said tubular envelope has a diameter of from 5 to 100 mm. 12. The heat retaining article of clothing according to claim 9, wherein said tubular envelope is attached to said sheet material such that, when said envelope is filled with air, a portion of said envelope which does not face said sheet material is inflated and projects away from said sheet material but the portion of said envelope which does face said sheet material is substantially plain. 13. The heat retaining article of clothing according to claim 9, wherein said article is a garment having wadded shoulders. 14. The heat retaining article according to claim 9, wherein said wadding material comprises conjugate fibers. 15. A heat retaining article of clothing comprising at least one inflatable envelope attached to a sheet material, said envelope being divided into plural chambers which are connected to each other, said envelope being made of an air-impermeable sheet consisting of a cloth treated with at least one synthetic or natural rubber, said envelope containing a wadding material consisting of at least two polymers having different melting points, one of said polymers having been melted to partially weld said wadding, thereby substantially preventing said wadding from moving about within said envelope, the heat retaining property of said article of clothing being controlled by adjusting the amount of air in said envelope. 16. The heat retaining article according to claim 15, wherein the density of said wadding is from 0.001 to 0.05 g/cm 3 based on the volume of the inflated envelope. 17. The heat retaining article according to claim 15, wherein said wadding material comprises conjugate fibers.
