I carry this same bag and 9x9 silnylon tarp for emergency use only. Its nice to hear from someone that has actually used it.A space blanket weighs hardly anything and takes up even less room. The SOL bivy is my go-to and paired with a kifaru lost park parka it is hard to beat. They are like 30 bucks on amazon and come with a stuff sack. Throw in a hammock and you are sleeping in the lap of luxury.
