Motorcycle heated apparel specialist Gerbing gives us yet another reason to love lithium-ion battery technology. Using a rechargeable 7-volt lithium-ion battery that will power the vest for up to 10 hours, the new Gyde Torrid heated vest features four heating grids — one in the neck, one in the back and two in the chest — and can reach temperatures up to 135F. Water and wind resistant, the 4-way stretchable shell material has a fleece-lined back for added comfort. $249.99. MC
