The bag is fastened to the wrap body such that the fastening area is 25% or less than the area of the bag. A pair of wings formed from an expandable, retractable material extends from each of opposite sides of the wrap body. Releasable fasteners are attached at the ends of at least two wings to attach to the ends of the opposite wings to secure the bag over the body part. ## Claims ### Claim 1 A wrap for applying thermal therapy to a body part comprising: a bag for containing a thermal agent, the bag having a bag area;
