Abstract: A collapsible cooler is configured to hold perishable foods, such as freshly killed big game on ice while in the field. The cooler is formed of an outer layer and an inner layer of waterproof nylon fabric with two intermediate layers of heat resistant insulation. In a closed configuration, the cooler is secured and drawn together via a set or mating series of hook and loop fasteners to form an aperture for exposing the neck and head portion of captured big game. In this configuration, a carcass of the captured game is kept cool and fresh from a surrounding stream of cold air. A natural drain is formed at the base of the cooler to allow for natural flow of fluid from the cooler to a surrounding area.
