Abstract
The present invention comprises a duplex thermal transfer pack. The pack includes a large bag containing many smaller sub bags. Each sub bag contains plain water. The volume within the large bag but outside the sub bags contains a second substance. This second substance freezes with a consistency akin to crushed ice or packed snow. The second substance allows the thermal transfer pack to remain malleable even when its contents are frozen.
