Frequently Asked Questions

Q: How many emergency mylar blankets come in this pack?

A: This listing includes 4 emergency mylar thermal blankets per packet, each individually folded for compact storage. That means you can keep one in your car, backpack, home emergency kit, and first aid kit all at once.

Q: Are these mylar space blankets reusable?

A: While the blankets are designed primarily as single-use emergency tools, they can be gently refolded and reused if handled with care. However, for critical survival situations, having a fresh blanket is always recommended — which is why the 4-pack is ideal for stocking up.

Q: What makes these different from a regular blanket?

A: Unlike traditional blankets, these use NASA-inspired reflective PET foil technology that reflects your body's radiant heat back toward you, retaining up to 90% of it. They are also windproof, waterproof, and fold down to a tiny size — making them far more practical for outdoor emergencies and survival situations.

Q: Can I use the mylar thermal blanket in summer too?

A: Absolutely! The reflective surface works both ways. In hot weather, you can use the blanket to reflect sunlight away — for example, as a windshield sunshade to keep your car cooler when parked in direct sunlight, or as a canopy/shelter to block solar heat while camping.

Q: What size are the blankets when fully unfolded?

A: Each blanket measures 130 × 210 cm (approximately 51 × 83 inches) when fully unfolded — large enough to wrap around an adult body comfortably or use as a makeshift shelter or poncho.
