Your jacket keeps you warm while you're moving. This keeps you alive when you stop.
The cold is the real danger
Hypothermia - not falls, not animals - is what kills most lost day hikers. Once you stop moving, your body loses heat faster than it makes it. At 40°F and wind, your time is measured in hours.
It does not take a disaster
A wrong fork. A twisted ankle. A phone at 9%. Most search-and-rescue calls start on easy trails, on day hikes, in weather that looked fine that morning.
It holds the heat you already have
The multi-layer lining reflects up to 90% of your body heat back at you. No batteries, no fire, nothing to set up - climb in and your own body does the work until help finds you.

Our Clients Say
Fits Everywhere.
Glovebox. Backpack. Bedside drawer. At 4 oz and smaller than a soda can, it disappears into your everyday life - and stays ready for the day you actually need it.
Engineered to Reflect. Not Just Insulate.
Most blankets and sleeping bags only slow down heat loss. Our product is built with a multi-layer thermal lining that reflects up to 90% of your body heat back to you - the same principle used in professional emergency and rescue gear.

Frequently Asked Questions
How does the ThermalGuard actually keep me warm?
The ThermalGuard is made from multi-layer metallized mylar - the same reflective material NASA used in the space program, and the basis for modern space blankets. It reflects up to 90% of your body heat back to you: instead of losing warmth to wind and cold air, your own body heat stays trapped inside - which is exactly what matters most in the hours after you stop moving. It's not a flimsy foil blanket; it's a full-body sleeping bag built for real conditions.
How small does it pack down?
Smaller than a soda can, and it weighs about 4 oz - light enough to forget it's there. It fits in a glove box, backpack pocket, emergency kit, or purse.
Does it ever expire or need maintenance?
No. There are no batteries, no moving parts, and nothing to maintain. You can keep it in your car or pack for years, and it'll work exactly the same the day you need it.
Why do you only sell one product?
Because we'd rather do one thing properly than a hundred things averagely. The ThermalGuard is our entire focus - every improvement, every bit of feedback from customers and field testers goes back into this one product. If we ever add something, it'll be because it earned its place, not to fill a page.
Who is this for?
Anyone who might ever be caught in the cold unexpectedly - hikers, campers, hunters, road-trippers, commuters in winter climates, or anyone building an emergency kit for their car or home. Most people buy one for themselves and end up getting extras for their family's vehicles.
How is this different from a cheap mylar blanket?
Standard mylar blankets are too thin, tear easily, and only cover part of your body. The ThermalGuard is a full enclosed sleeping bag, made from a better multi-layer material, and sized 20% larger than standard mylar blankets - so it actually holds up when it matters.
What if I'm not satisfied?
Simple: if you're not happy with your ThermalGuard for any reason, you have 30 days to return it for a full refund - no complicated conditions, and you don't need to justify why. If your item arrives damaged, defective, or incorrect, we'll cover everything including return shipping. For change-of-mind returns, we just ask that you cover the return postage. Refunds are issued within 10 business days.
