Abstract: A hunter's gear bag provides a collapsible, foldable container capable of removable attachment to hunting tree stands for the convenient storage of hunting gear, food and other equipment and items useful to hunters during time spent in a tree stand awaiting prey. A bag is constructed from panels of fabric to form a pocket having a top opening for the insertion and removal of items. The bag is attached at its top opening to a frame that has pivoting members which rotate between a collapsed position when the bag is closed to a expanded position when the bag is open. One of the frame members is capable of releasable attachment to the hunter's stand. The gear bag is foldable to form an unobtrusive attachment to the hunter's stand while the stand is transported to or from the place of use and during deployment in a tree. The panels of fabric used to construct the pocket may be water-resistant and/or camouflage fabric.
