BACKGROUND OF THE INVENTION This invention pertains to a hand warmer for use in BRIEF DESCRIPTION OF THE DRAWINGS cold environments, especially for outdoor sportsmen. The above mentioned and other features and objects Many kinds of hand warmers or muffs are available, of the present invention, and the manner of attaining some being designed for formal clothing, others for them, will become more apparent and the. invention outdoor sports clothing. The hand warmer of the pres itself will be better understood by reference to the fol ent invention is intended to be worn as part of outdoor lowing description of an embodiment of the invention sports clothing and is an'improvement upon those hand taken in conjunction with the accompanying drawings, vwarmers which have various straps or strings for the wherein: , wearing or use thereof.
