Gear Up For Colder Temps With December's Greatest Fitness and Health Products

"This cozy Skida Hat ($36) comes in tons of fun and vibrant prints to brighten up a dreary Winter day. I love that it's lined with fleece so it's warm and also wicks away moisture, so it's perfect for cold-weather sports like cross country skiing, hiking, running, or just cruising around while running errands." — Jenny Sugar, editor, Fitness
