Gel click hand warmers are mini gel heat pads which will provide warmth from 20-30 mins. Suitable for those on the move or requiring instant heat. The heat pads heat up to a hot temperature but not too hot to scold the skin. Can be re-used by simply boiling in water for a few minutes leaving it ready for its next use. As soon as they are triggered by a click they heat up instantly and solidify, then they can be massaged to make them flexible and comfortable to mould to the hands or body. Once the gel click hand warmers are clicked they start a chemical reaction which heats up the gel pad almost instantly, they then gradually cool down after some time (the time they last depends on size). An aqueous salt solution is used which can be super cooled to be used when necessary.
Gel click hand warmers are a instant outdoor solution to cold hands, they can be reused, but not on the move, so taking out a few at a time with be better, as when one runs out, another can be clicked when the cold bites again. The gel hand warmers can be kept in a pocket as they are small and lightweight.
