Frequently Asked Questions

Q: How do Mylar emergency thermal space blankets work?

A: Mylar emergency blankets are made from a thin, reflective PET film with a metallic coating. The reflective surface bounces radiant body heat back toward you, helping the blanket retain up to 90% of your body's warmth. They also block wind and moisture, making them effective in a wide range of outdoor conditions.

Q: Are these space blankets reusable?

A: While these Mylar blankets can be carefully refolded and reused, they are primarily designed for emergency single-use situations. For best performance in critical situations, we recommend replacing any blanket that has been torn or punctured.

Q: How compact are these blankets when folded?

A: Each blanket folds down to approximately credit-card size and weighs just 40g, making it easy to slip into a pocket, first aid kit, EDC bag, or glove compartment without taking up noticeable space.

Q: What are all the ways I can use a Mylar space blanket?

A: These versatile blankets can be used as a body warmer, rain poncho, emergency canopy or shelter, sleeping bag liner, backpack cover, reflective rescue signal, and even as a car windshield sun shield to reduce interior heat absorption when parked in direct sunlight.

Q: Why does this pack include 4 blankets?

A: Having multiple blankets means you're prepared to help not just yourself but also family members or fellow travelers in an unexpected situation. It also allows you to distribute blankets across different bags or kits so you're always covered.
