Review: Quality material, thicker and compact - The larger pack on left holds all 4 of the emergency blankets. It is a nice small compact holder for all 4 blankets. It measures 5.5in Length, 4in Wide and 2in Deep. The carabiner is a nice touch to quickly attach to a bag, belt ect. The individual blankets come in their own separate bags which is nice if you want to keep them in multiple locations like a car, house, bug out bag etc or share with someone. The individual blankets take up very little room and measure 3.5in Length, 2in Wide and 1in Deep and could probably be squeezed even smaller to take up less room. Quality- I opened 1 of the individual blankets to check out how well it would be if I needed to use it. The material is much thicker than the typical emergency blankets I've seen elsewhere and doesn't feel like the others where it feels like they would rip super easily. It is definitely thicker and more sturdy than others and the non mylar side feels thick like a gallon zip lock bag and not like a cheap plastic bag from a grocery store. My opinion is that the emergency blankets is worth the higher price than cheaper ones. Would be able to reuse without worrying of it ripping and the multiple individual packages allows you to easily place or tie them to multiple locations so one is always handy.
Review: Thicker than traditional ponchos - Quality ponchos at a good price. I have these in my bug out bag and love them. They are thicker than traditional ponchos. Great purchase

Quality ponchos at a good price. I have these in my bug out bag and love them. They are thicker than traditional ponchos. Great purchase

### ⭐⭐⭐⭐⭐ Good emergency blankets!
*by K***Y on August 6, 2025*

I have never used this product as a way to preserve body heat. However, I work as a firefighter, and my department uses cheaper emergency blankets to treat shock and hypothermia patients. Those blankets tear when one just looks at them. While these blankets are thin, they are designed to be lightweight, compact, and fairly easy to deploy. These blankets meet that description. I took one out of a package and tried to tear it. It did not tear easily. That alone makes it a million times better than the ones my department uses for patient care. I put two of these in my bug out bag and two in my car for winter use. I have seen some negative reviews of these where people complained they were thin. Yes, that is part of the design. I did not try use one as a tarp. I would not expect it to survive that type of use. A person has to understand what a product is as well as its intended use. Like I said before, these are a million times better than the ones my department uses. The only drawback is that these will not be able to get put back into their tiny storage bags once they are taken out. I took the two I will use in my bug out bag out of the be stuff roll and placed them inside the larger pouch the four pouches came in.
