Abstract: In one embodiment, a thermoregulation device to be worn by a user comprises a body having one or more receiving portions, the body having an axis extending about its height, wherein the receiving portions extend along the axis and each removably receive and hold in position a thermoregulation material; and at least one strap coupled to at least one portion of the body and extend about a portion of the user when worn by the user. The at least one strap assists in holding the body tightly against a spine of the user when worn such that the axis is substantially aligned with the spine of the user. And the portion and the receiving portions hold the thermoregulation material in position along the axis such that the thermoregulation material is held in proximity and adjacent to the spine of the user when worn by the user.
