handwarmer
Palm-sized heat source
A handwarmer is a small device designed to generate heat for warming cold hands.
Disposable versions contain chemicals that produce heat when activated; reusable types include gel packs and battery-powered units.
Handwarmers slip into pockets or gloves: I tucked a handwarmer into each mitten before heading out.
