To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
These are basic emergency blankets. They're very thin - which is good because they're lightweight and small. This is a pack of four. Each one individually is about the size of an egg roll after two bites have been eaten. So, it's small enough to throw in your bug-out bag and you'll never notice the extra size or weight.
But don't expect much. They sort of feel like Christmas wrapping paper that won't tear easily. Worth having on hand. But not on my list of essentials.
