The Mart Cobra Emergency Blanket 100-Pack offers a large quantity of aluminized Mylar blankets designed to retain up to 90% of body heat, making them very effective in emergency situations like camping, hiking, or disaster preparedness. Each blanket measures a generous 82 by 52 inches, providing ample coverage for an adult. At 12 microns thick and weighing about 2 ounces, these blankets strike a good balance between being lightweight and durable. They are made from tear-resistant material, so they should hold up reasonably well for multiple uses, which is a plus for long-term emergency kits.

These blankets are water resistant and windproof, helping to block out harsh weather elements. When folded, they pack down compactly, making them easy to carry in backpacks or store in emergency kits without adding much bulk. The main downside is that while they are durable for Mylar blankets, they are not as rugged as heavier fabric blankets, so rough handling could cause tears. Also, the water resistance is helpful but doesn’t mean fully waterproof in heavy rain.

This bulk pack is well suited for groups, organizations, or anyone wanting to stock up on reliable, lightweight emergency warmth at a good value.

Buying Guide for the Best Mylar Blankets

Mylar blankets, also known as emergency blankets or space blankets, are a crucial item for outdoor enthusiasts, emergency preparedness kits, and anyone who wants to be prepared for unexpected situations. These blankets are designed to reflect body heat and provide warmth in cold conditions, making them an essential tool for survival. When choosing a mylar blanket, it's important to consider several key specifications to ensure you select the best one for your needs.
SizeThe size of a mylar blanket is important because it determines how much coverage you will get. Mylar blankets typically come in various sizes, ranging from small, single-person blankets to larger ones that can cover multiple people or be used as a shelter. If you are planning to use the blanket for personal warmth, a standard size (around 52 x 82 inches) should suffice. For group use or to create a makeshift shelter, consider a larger size. Your intended use will guide you in choosing the right size.
ThicknessThickness affects the durability and insulation properties of the mylar blanket. Thicker blankets (around 12 microns) are more durable and provide better insulation, making them suitable for harsh conditions and repeated use. Thinner blankets (around 6 microns) are lighter and more compact, ideal for single-use or emergency situations where portability is key. Consider how you plan to use the blanket and the conditions you expect to face when deciding on the thickness.
WeightWeight is a crucial factor, especially if you plan to carry the mylar blanket in a backpack or emergency kit. Lighter blankets are easier to carry and take up less space, making them ideal for hikers, campers, and travelers. Heavier blankets, while bulkier, may offer better durability and warmth. Think about how much weight you are willing to carry and balance it with the level of protection you need.
ReflectivityReflectivity refers to the blanket's ability to reflect body heat back to you, which is essential for staying warm. Most mylar blankets reflect about 90% of body heat, but some high-quality options can reflect up to 95%. Higher reflectivity means better heat retention, which is crucial in extremely cold conditions. If you are preparing for very cold environments, opt for a blanket with higher reflectivity.
DurabilityDurability is important if you plan to use the mylar blanket multiple times or in rugged conditions. More durable blankets are less likely to tear and can withstand rough handling. Look for blankets made from high-quality materials and with reinforced edges. If you need a blanket for emergency use only, durability may be less of a concern, but for regular outdoor activities, a more durable option is preferable.
Waterproof and WindproofA good mylar blanket should be both waterproof and windproof to protect you from the elements. This feature ensures that you stay dry and warm even in wet or windy conditions. Most mylar blankets offer these properties, but it's always good to check the product specifications. If you expect to face harsh weather, prioritize blankets that explicitly state they are waterproof and windproof.
PackabilityPackability refers to how easily the blanket can be folded and stored. A highly packable blanket will fold down to a small size, making it convenient to carry in a backpack or emergency kit. This is particularly important for hikers, campers, and anyone who needs to save space. Check the dimensions of the blanket when packed and ensure it fits your storage requirements.
