a strap configured for releasably coupling the heat exchanging pack to the portion of the body, the strap including a first portion extending through the first strap receiving portion, a second portion extending between the first strap receiving portion and the second strap receiving portion, a third portion extending through the second strap receiving portion, and a fourth portion extending out from the first passageway, wherein the fourth portion releasably attaches to the substance receiving portion.

2. The heat exchanging pack of claim 1 , wherein the substance receiving portion includes a one-way valve configured to allow air to pass in a direction from an interior of the substance receiving portion to an ambient environment.

3. The heat exchanging pack of claim 1 , wherein the substance receiving portion includes a mouth having a resealable mechanism for selectively opening or closing the mouth, wherein the mouth extends between the first strap receiving portion and the second strap receiving portion.

4. The heat exchanging pack of claim 3 , wherein the resealable mechanism includes a slider mechanism configured to open or close the mouth depending on a position of the slider mechanism relative to the mouth.

5. The heat exchanging pack of claim 1 , wherein the substance receiving portion is formed between a central portion of a first wall and a central portion of a second wall, wherein the first strap receiving portion is formed between a first lateral portion of the first wall and a first lateral portion of the second wall, and wherein the second strap receiving portion is formed between a second lateral portion of the first wall and a second lateral portion of the second wall.

6. The heat exchanging pack of claim 5 , wherein a first partitioning seam joins the first wall to the second wall between the substance receiving portion and the first strap receiving portion and wherein a second partitioning seam joins the first wall to the second wall between the substance receiving portion and the second strap receiving portion.

7. The heat exchanging pack of claim 6 , wherein the first partitioning seam and the second partitioning seam are formed during a heat sealing process applied to the first wall and the second wall.

8. The heat exchanging pack of claim 5 , wherein the first wall and the second wall are formed from a film of a polymeric material.

9. The heat exchanging pack of claim 8 , wherein the polymeric material is one of low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), or high-density polyethylene (HDPE).

10. The heat exchanging pack of claim 5 , wherein the first wall and the second wall are formed from a sheet of material having a fold separating the first wall from the second wall.

11. The heat exchanging pack of claim 1 , wherein the substance receiving portion and the second portion of the strap cooperate to form a first opening configured to receive the portion of the user therebetween, and wherein the substance receiving portion and the fourth portion of the strap cooperate to form a second opening configured to receive the portion of the user therebetween.

12. The heat exchanging pack of claim 1 , wherein the coupling surface has one of a hook pattern or a loop pattern disposed thereon, and wherein a coupling device disposed on the fourth portion of the strap includes the other of the hook pattern or the loop pattern thereon, the coupling device configured to be releasably coupled to the coupling surface.

13. A method of manufacturing a heat exchanging pack comprising the steps of:

providing a bag, the bag including a first wall coupled to a second wall at a first side edge and an opposing second side edge of the bag, the bag including a first end edge and an opposing second end edge, the first end edge and the second end edge extending between the first side edge and the second side edge, wherein a mouth is formed adjacent the first end edge;

forming a first partitioning seam adjacent the first side edge, the first partitioning seam including a first portion of the first wall coupled to a first portion of the second wall, a first passageway formed between the first side edge and the first partitioning seam;

forming a second partitioning seam adjacent the second side edge, the second partitioning seam including a second portion of the first wall coupled to a second portion of the second wall, a second passageway formed between the second side edge and the second partitioning seam; and

inserting a continuous strap having a first end and an opposing second end through the first passageway in a direction from the first end edge to the second end edge, extending the strap from the first passageway to the second passageway so the strap extending from the first passageway to the second passages way is disposed exterior and adjacent to the second end edge, and extending the strap through the second passageway in a direction from the second end edge to the first end edge.

14. The method of claim 13 , wherein the first partitioning seam and the second partitioning seam are formed in a heat sealing process.

15. The method of claim 13 , further comprising the steps of:

forming an opening at each end of each of the first passageway and the second passageway.

16. A method of using a heat exchanging pack, the method comprising the steps of:

providing a heat exchanging pack comprising a substance receiving portion configured to receive a cold or hot substance therein, a first strap receiving portion disposed adjacent a first side of the substance receiving portion, a second strap receiving portion disposed adjacent a second side of the substance receiving portion, and a strap configured for releasably coupling the heat exchanging pack to the portion of the body, the strap including a first portion extending through the first strap receiving portion, a second portion extending between the first strap receiving portion and the second strap receiving portion, a third portion extending through the second strap receiving portion, and a fourth portion extending out of the first strap receiving portion;

placing a portion of a user between the substance receiving portion of the heat exchanging pack and the second portion of the strap;

extending the fourth portion of the strap out of the first strap receiving portion to constrict the second portion of the strap around the portion of the user.

17. The method of claim 16 , further comprising a step of removing air from the interior of the heat exchanging pack through a one-way valve coupled to the substance receiving portion.

18. The method of claim 16 , further comprising the steps of:

extending the fourth portion of the strap around the portion of the user; and

coupling a coupling device of the fourth portion of the strap to a coupling surface of the substance receiving portion.
