The 3×5 is great as a hand warmer, in pockets, under beanies, and works great for spot treatment, arthritis, poor circulation and hot stone massage. The 3×5 lasts about an hour depending on how well you insulate it. You can also use the heat pack as a cold pack. Just place it in the freezer for up to one hour and it will stay soft and flexible.
These hand warmers and heat packs are perfect for outdoor recreation, dog walking, camping, hiking, spectator sports, and snowmobiling. Made with durable, medical grade material, our portable heating packs warm up in 60 seconds.
