Abstract: A multi-conforming beverage holder having a main body and a cuff. The main body is formed from one or more panels of insulating material having various edges, and the cuff is formed from one or more panels of elastic material having various edges. The edges of the main body are connected to generally form a cylinder having sidewalls, a bottom wall, and an open top edge. The edges of the cuff are connected to generally form a cylinder having sidewalls and open top and bottom edges. The open bottom edge of the cuff is connected to the open top edge of the main body. The cuff is operable to be folded downward from an unfolded position to a folded position to accommodate beverage vessels of various shapes and sizes. The holder may also include one or more grippers formed from nonslip material disposed on inner surfaces of the sidewalls of the main body and/or cuff, to retain beverage vessels more securely within the holder.
