The Ignik 24-Hour XL Warmers are air-activated heat packs designed to provide consistent warmth in cold conditions. Each warmer delivers heat for up to 24 hours and activates within 5–10 minutes after exposure to air. The warmers use natural, biodegradable materials and come in a resealable AirBarrier™ pouch, which helps regulate airflow and allows partially used warmers to be stored and reused for up to 72 hours. They are suitable for use in pockets, jackets, or sleeping bags and are commonly used for camping, outdoor work, or cold-weather activities. The outer packaging is reusable and recyclable, and the internal materials can be composted after use.
