Protecting and grip-enhancing device

A protecting and grip-enhancing device includes an inner body formed of a first material and having opposite outer sides, a thermally insulating outer body formed of a second material and secured to at least one outer side of the inner body and continuously covering a substantial portion thereof, and hinge structure joining two adjacent regions of the device to facilitate folding of the adjacent regions relative to each other along the hinge structure. Plural hinge structures may be provided, each including a reduced thickness of outer body material and stitching extending through the reduced thickness and an underlying portion of the inner body. The outer body may include relatively thick and relatively thin regions and the thick region may include alternating raised ribs and open-ended channels. The device may be in the form of a mitt or a potholder.
