- — In-game description
A Heatpack is a consumable item that fully and immediately replenishes a player's temperature meter upon use in DayZ.
Heatpacks are not an item that needs to be carried unless the player is going for a swim to an island on a rainy night. It is recommended they have a Heatpack in their inventory as being in water and rainy/cold weather reduces body temperature rapidly.
