The Bar Mitts Handlebar Mittens are a great solution to cold hands during winter riding. These neoprene Handlebar Mitts use 5.5mm neoprene to create a waterproof and insulating pocket in which you insert your hands while riding. Because the Bar Mitts enclose your brake levers and shifters, bicycle control is easily handled with your hands inside the mitts. If you are riding in cold weather with snow, ice or rain the Bar Mitts keep your hands warm while riding and allow you to use a very lightweight glove, increasing dexterity.
