Meet the little heat packs made for your Flipmits. Our reusable hand warmers slide right into your Flipmits pocket to give your hands an instant burst of heat whenever they need it. Just click. Heat. Walk. Repeat. Wear them against the back of your hands for comfortable warmth while keeping your fingers free—or move them to your palm whenever you want the heat there. When they cool down, recharge them in hot water and they’re ready to go again. * Colors are selected at random. ** Heat Packs can get sometimes activated during transit. No problem, just follow the instructions to reset it.
