Used it to show how stupid I can be. 26F. 5am. I can throw on overpants, the warmnsafe jacket liner, glove liners, neck gaiter, thin toboggan, and helmet pretty quickly. Start bike, attach liner to glove liners, attach jacket power cord to bike. Backed bike out of garage in L shaped maneuver, like most mornings. Just as I was starting to do the big lean and clicking into 1st gear to start my downhill journey to the street, bike had no power. I had left the sidestand down. Easy fix. But it was disconcerting for a second. Glove liners, or rather, power to the glove liners, was out for some reason. Warm and toasty everywhere except hands. Went from cold, to painful, to nail beds itching. A testament to how nice heated glove liners are.
