Your safety is our priority, but your satisfaction is our promise. If you don't feel 100% more prepared for the unexpected, we'll refund every penny. No cold feet, no risks, just warmth.
How does the heat tech work?
The interior is lined with a space-age reflective material that captures up to 90% of your radiated body heat. Instead of losing warmth to the air, it bounces right back to you, keeping your core temperature stable in freezing conditions.
Is it actually reusable?
Absolutely! While designed for emergencies, the durable tear-resistant material allows you to fold it back up and tuck it into its pouch for the next adventure or unexpected roadside nap.
Will I fit inside?
We've sized this to fit most adults comfortably. It's wide enough to climb into even with your winter jacket on, ensuring you don't have to shed layers to stay protected.
What about the whistle?
Each kit includes a high-decibel emergency whistle integrated into the drawstring. It's designed to be heard over wind and engine noise, so you can signal for help without losing your breath.
