But now it's time to fight back the best way you know how: harnessing the power of a good, solid vest.
Introducing the Heated Vest From Frontgate, battery-powered outerwear that ups your body's BTU quotient while enhancing your winter wardrobe.
The setup is pure simplicity: the vest is equipped with a discreetly hidden 7.4 volt lithium-ion battery, with enough juice to keep you extra-toasty for two to four hours. (In other words, just enough time to keep you from freezing to death while waiting for the Blue Line.)
Three heating pads embedded in the coat—two in front and one in back—can be adjusted according to your current needs: low, medium or walking on Wacker Drive in January (aka, high). And if you're worried about looking like a robot lumberjack, don't be: the heating pads and control mechanism are nestled inside the vest, completely invisible to anyone except those you let get close to you, who will no doubt feel the warmth emanating from your direction.
And then, they'll probably just assume it's your personality.
