Grabber Performance Group-the people who make those little air-activated handwarmers that have allowed many a deer hunter to remain on stand for that last cold hour when the buck finally showed up-has improved an already good thing. The Grabber MyCoal Adhesive Body Warmers, designed to relieve muscle aches or joint pain, attach to a garment on the hunter’s lower back (not directly on the skin), one over each kidney, through which all blood flows. The result: You’ll stay warmer overall. The heaters last up to 12 hours. About $1.99. 800-423-1233;
