Sale priceHow does PREFIRE generate heat?
PREFIRE uses an air-activated reaction. Once opened, oxygen interacts with the natural iron-based materials inside the pouch, producing steady, consistent heat without batteries, charging, or electricity.
How quickly does PREFIRE heat up?
PREFIRE begins warming immediately after activation and reaches full heat within a few minutes, depending on airflow and surrounding temperature.
How long does each pouch last?
Each PREFIRE pouch delivers 8+ hours of consistent heat, with some lasting up to 12 hours depending on airflow, environment, and usage.
How hot does PREFIRE get?
PREFIRE is designed to reach a steady, comfortable temperature range (typically around 135°F–160°F / 57°C–71°C), avoiding sharp spikes while maintaining reliable warmth over time.
What makes PREFIRE feel different?
PREFIRE is built with a soft, premium outer layer designed to feel comfortable in-hand or in-pocket. Unlike traditional hand warmers, it avoids the crinkly, rigid feel of cheaper materials.
What is inside each pouch?
Each pouch contains a simple combination of:
* Iron powder
* Water
* Salt
* Activated charcoal
* Vermiculite
These materials create a natural heat reaction when exposed to air.
How do I use PREFIRE?
1. RIP OPEN
2. SHAKE WELL
3. GET HEATED
That’s it. Heat builds within minutes and stays consistent for hours.
Where should I keep it while using it?
PREFIRE works best when kept close:
* in your hands
* inside pockets
* in gloves
This helps retain heat and extend performance.
When does PREFIRE work best?
When does PREFIRE work best?
Anytime cold becomes a distraction:
* outdoor activities
* cold commutes
* long sessions (gaming, work, events)
* early mornings or late nights
Do I need to recharge or prepare anything?
No. PREFIRE is air-activated and ready to go.
No charging, cables, or setup required.
