Pref*re hand warmers deliver steady warmth for 8 to 12 hours or more, depending on airflow and environment. Once activated, the heat builds gradually and stays consistent throughout the day, making them ideal for winter weather, outdoor activities, and long gaming sessions.

Pref*re uses an air-activated heat reaction. When the pouch is opened, oxygen reacts with the iron powder inside the warmer and produces heat through a controlled oxidation process. Just open the pouch, shake it well, and the warmth begins within minutes.

Each Pref*re pouch contains iron powder, water, salt, activated charcoal, and vermiculite. These naturally derived materials work together to produce steady warmth when exposed to air.
