Frequently Asked Questions

Q: How many emergency Mylar thermal blankets are included in one pack?

A: Each pack includes 4 individual Mylar thermal space blankets, giving you plenty to stock your car, first aid kit, backpack, and home emergency supply in one purchase.

Q: How big are the blankets when fully unfolded?

A: When fully unfolded, each blanket measures 130 × 210 cm (approximately 51 × 83 inches) — large enough to wrap around an adult body fully. They fold back down to a compact, pocket-friendly size for easy storage.

Q: Can these space blankets be used in hot weather, not just cold?

A: Absolutely. The reflective Mylar surface works both ways — in warm conditions, you can use it to reflect sunlight and reduce heat absorption, such as placing it over a car windshield or using it as a sun shelter canopy.

Q: Are these blankets waterproof and windproof?

A: Yes. The PET film + reflective coating construction makes these blankets both windproof and waterproof, so they can function effectively as a rain poncho, emergency shelter, or protective ground cover.

Q: What makes these blankets suitable for signaling rescuers?

A: The highly polished silver reflective surface acts like a mirror, capable of catching sunlight and flashing a visible signal to aircraft, search parties, or rescue personnel from considerable distances — a critical feature in any survival situation.
