Lil Pricey... But I laid inside of it for 10 minutes and felt My Body Heat Radiating Back At Me. I wish they were more affordable because I would buy another one. No more Freezing on Those Cold Camp Nights...

Saved my ass on a very cold night on Standing Indian mountain NC. all we could do was huddle in our tent in a freezing and windy night but we had internet! Seems so hold charge shorter time each charge but I like it.

Bought these to throw in my box of camping gear and glad I did.  When it got a little warm one night,  I put one by my head and slept very well. For the money and size,  it's a good investment for tent campers.

Great for adding to your sleeping bag or using in hostel beds! Also nice to have if you are the type who needs a sheet/cover even when sleeping in hot weather - keeps you relatively cool compared to other bedding.

Very helpful during extremely cold weather.  Can place it in any room you like to warm it up a bit.  Great for areas lacking enough heat.

Used these  camping. It was hotter then hell. So grateful I had these. Definitely did their job.

Excellent camping gear, gets a good glow going on the coals in short order. Both handles can get pretty hot, so be sure to have a potholder or glove on hand too.

Just found another trick for it, which is as a windshield and pot stand for cooking over my single burner liquid fuel stove.

This hat is the go-to for cold nights, camping trips, or when you just want to feel really cool for wearing a beanie.

Stay warm without worrying about your house battery going dead. Works well. Read the directions to turn it on. Uses propane and keeps a 22' rv cozy.

It's amazing how such a small thing can make me feel so much warmer!  It may not be a fashion statement, but it helps keep me comfortable out in the cold.  I love that I can pull it up over my chin when it's really cold out.

This is a great price but they are not nearly as large as a person actually needs to wrap up in.  They do  reflect your body heat back and they do break the wind but do NOT curl up in one and expect to stay warm all night.  Mylar does not breath so you will wake up damp and probably cold.

Because of the price and their light weight I carry two or three in each vehicle and take a couple with me when ever I go camping.  There never seems to be an end to the uses you can put them to.

They are fantastic for reflecting heat  back to you from a camp fire and I think they would make a great signaling device although I have never had an occasion to see if that's true.  They are truly waterproof so if you are trying to keep the rain off and have nothing else they will sure help.  One time my kids put a handful of pop corn along with some butter in a torn section of one and tossed it into the fire.  A few minutes later they took it out and had a good treat.  Of course some of it was un-poped and other parts were burned but some of it was eatable.  On another trip my wife lined a dutch oven with another torn section and baked a pineapple upside down cake in it.  That way she didn't have to scrub out the cast iron pot. We all use them for ground cloths to put under our sleeping bags and on occasions have used them for make-shift shelters.  My oldest son took a small piece of one and tied a string to it.  He then hung it over a trap he had set for a bob cat.  Worked great.  He got $275 for the hide.

I see where a few people have complained about the noise they make when you move around in one.  My feelings on that are:  If you're in a true survival situation, noise is going to be the least of  your problems.

Great price on them seeing that it comes in a 10 pack. I keep a few of them in my survival kit in the car on the long winter trips to and from New York just in case of emergency.  Tested one out on a colder southern night and it truly did keep me warm though!! Definately did not need a 10 pack but was the smallest option so no big deal!

Love how it is small, how it breathes so you don't just wake up in sweat. You should carry this with you on every day hike, it might save your life. Warm to about 45 degrees. It would keep you from freezing even if it went below 32, I bet, but you'd certainly shiver all night. Would definitely save your life. Could definitely turn a disaster into just one annoying night, so instead of dying you could just whine about it the rest of your life.

I use it on the outside of my sleeping bag to extend the comfort and increase the warmth by about 10 degrees with almost no weight.

Contrary to what you'd think, this WILL keep you cool in the summer, and warm in the winter. Plus keeps out smoke, dust, and debris. Good item to have in a BOB or other go-bag. Also can function as a makeshift bandage, sling, or cordage. Will definitely buy again.

This thing is /comfy/. I thought it'd be bulky, but it went above and beyond. Keeps me pretty damn warm. Can't wait to use it on camp outs.

this thing is great for camping, day at the lake or just whenever your outside, stays cool.. Pair it with some sun glasses and you will beat the sun

This definitely added warmth to my sleeping bag.  It was very cold where I was camping and it was definitely worth it.  The only negative aspect of having both a regular sleeping bag and a liner was that I got a little tangled up in the layers when I would try to roll over at night.  But it was freezing outside, so it was definitely worth it!!
