In 1964, NASA engineers faced a problem that had nothing to do with rockets. Astronauts in the vacuum of space needed a material that could reflect 90% of their body heat back to them while weighing almost nothing and occupying zero cargo space. The solution they developed — metallized polyethylene terephthalate, colloquially known as the space blanket — has saved more lives on Earth than it ever did in orbit.
The Apollo Liner is the direct descendant of that NASA innovation, manufactured to the same reflective principle but engineered for the scenarios that actually happen to people: a car breaking down in a winter storm, an unexpected night on a hiking trail, a first-aid kit that suddenly becomes the only thing standing between a victim and hypothermia. Each blanket weighs less than 60 grams and folds down to the size of a deck of cards, yet reflects up to 90% of radiant body heat. It is not a replacement for a sleeping bag — it is the thing you carry when circumstances do not permit a sleeping bag.
The metallized surface is waterproof and windproof — two properties that ordinary fabric blankets surrender immediately when wet. In a medical emergency, the reflective surface helps first responders locate victims in low-visibility conditions. In a vehicle emergency kit, it doubles as a ground cover, a signaling device, or an improvised shelter wall. We sell these in packs ranging from a single unit to a 20-pack because we know the buyer who buys one will eventually wish they had bought five — one for the car, one for the hiking pack, one for the home emergency kit, and two for the friends who saw theirs and asked where to get one.
Space is cold. Your trunk should not be.
Key Features

Application Scenarios
The Apollo Liner belongs wherever preparedness meets reality. Outdoor enthusiasts — hikers, campers, trail runners, mountain bikers — carry one in their pack because they know the difference between "I will be back before dark" and "the trail washed out and now it is dark." Vehicle emergency kits without a thermal blanket are incomplete: a breakdown in winter conditions with a dead heater turns a car from shelter to refrigerator within 20 minutes. First responders and SAR teams carry multiples because hypothermia is the second-leading cause of death in outdoor emergencies, and the window for intervention is measured in minutes, not hours. Marathon organizers and event medical tents stock them by the case for post-race cooling — the reflective surface works in both directions, shielding overheated athletes from radiant sun while they recover. And for the family that wants a single emergency-preparedness item that covers the most ground for the least weight and cost, there is no better starting point.
Frequently Asked Questions
Q: How does a Mylar blanket actually keep you warm if it is so thin?
A: Your body constantly radiates infrared heat — this is the warmth you feel standing near someone on a cold day. A Mylar blanket reflects up to 90% of that radiant heat back toward your body instead of letting it escape into the environment. It also blocks convective heat loss from wind and evaporative heat loss from moisture. Combined, these effects can raise your perceived temperature by 10-15 degrees. It is not insulation in the traditional sense — it is a radiant barrier, and it works because radiation accounts for roughly 60% of body heat loss in cold conditions.
Q: Can I reuse a Mylar blanket or is it single-use?
A: With careful handling, Mylar blankets can be reused multiple times. Fold them gently along existing crease lines rather than crumpling them — the material develops pinhole tears if crushed. For emergency kits where reliability is critical, rotate your blanket annually and repurpose the old one as a ground cover or equipment wrap.
Q: Is this loud and crinkly like cheap emergency blankets?
A: All Mylar blankets produce some crinkle noise — it is inherent to the metallized film material. However, the Apollo Liner uses a slightly thicker gauge of Mylar than the ultra-budget alternatives, which reduces both noise and tearing. In a genuine emergency, the crinkle is the sound of staying warm.
Q: Which pack size should I buy for a family of four?
A: We recommend the 5-pack minimum for a single vehicle: one per person plus a spare. For a household with two vehicles and outdoor activity, the 10-pack covers both cars and hiking packs with room to replace worn units. Organizations and teams should look at the 20-pack for economies of scale.
Q: Will this work as a sleeping bag replacement?
A: No — and we say this explicitly because confusing the two is dangerous. A Mylar blanket reflects radiant heat but provides zero insulation against conduction (cold ground) or convection (moving air). In a survival scenario, wrap yourself in the blanket first, then use whatever insulation you have — clothing, leaves, a backpack — on top. The blanket is a layer in a system, not the whole system.
Q: Does the reflective side go in or out?
A: For keeping warm, the reflective (silver) side faces your body to reflect radiant heat back toward you. For keeping cool in hot sun, the reflective side faces outward to bounce solar radiation away. This dual-mode behavior is why Mylar blankets appear in both first-aid kits and marathon finish lines.
Q: How long does a Mylar blanket last in storage?
A: Indefinitely, provided it stays sealed in its packaging and is stored away from direct sunlight and temperature extremes. The Mylar material does not degrade over time the way fabric does — there is no mold, no rot, no insect damage. The limiting factor is the folded creases eventually weakening after many years, but a sealed blanket stored in a vehicle glovebox or emergency kit will be ready when you need it.
