This little peice of Mylar can mean the diference between shivering all night as the cold zaps all your energy and being able to get back up at first light to make your way back to safety. I've been caught out without a "space blanket" before. If you don;t believe the heating powers of a vapor barrier, go get a large trash bag and hudle with it wrapped around your shoulders, within minutes you should feel the trapped heat building. Added bonus to tthis blacket are the survival instructions and illustrations tp keep you enlightened and entertained.

These are lifesavers as everyone knows ... I use mine as an ultra-lite ground cover to sleep on, as well as having it for emergencies ... I just don't see much physical difference between this and the origional mylar space blankets ... the printed survival/medical techniques are a small added bonus ... I recommend these as long as you're not paying too much more for them, as compared to a regular ol' mylar emergency blanket.

i use this blanket as a lightweight ground cover for backpacking in the sierra nevada mountains for my wife and me mainly to keep our stuff clean. we do not typically bring a tent, we just use this, our sleeping pad, a warm down bag, and a second emergency blanket for rain protection if needed. It holds up great for week long trips. It should be noted that it can be fussy to use in high winds, other than that, these are great to bring along!

I use this sheet as an ultralight groundcloth when sleeping in the open or under a tarp. It is very lightweight and large enough for two.

Great product. Inexpensive and way more durable than any other blanket.

Well thankfully I haven't had to use it yet but it sure is a nice small pack it cames in it fits almost any where.
