UST 20-PGR0010-08 Survival Blanket/Tarp 2.0 with Windproof and Waterproof Material for Emergency, Camping, Hiking and Outdoors, Orange

I hoped that these would allow tent camping in sub freezing temperatures. That prospect was previously pretty dicey (especially if my wife was along) even with a propane heater. The heat just dissipates too quickly and doesn't filter down to the ground where you are sleeping no matter how long/high you run it. So I ordered 3 to give it a try and waited for a cold night in the low 20's. I set up the tent, clamped the blankets to it, threw in a heater and an air mattress and jumped in. As soon as I turned on the heater I knew that this was going to work well. It immediately started reflecting heat onto my face and didn't just gather at the top before exiting. After getting the chill out from having the door open I had to turn the heat down to medium and then low because I was starting to sweat. Before this experiment, anything at or colder than 35 usually required running the heater all night on high just to stay comfortable. The 20's were not really doable or would at the very least not allow you to be outside of the sleeping bag in the tent. Now it will definitely be possible and seemingly pretty easy to stay warm. On top of reflecting the heat extraordinarily well, they also work as a wind break to keep any breeze from tearing through the thin tent wall and chilling you to the bone. Unfortunately, going outside will still be a nightmare, but there's not much I can do about that. In terms of longevity, who knows. I unpacked, clamped, left on tent all night and into the next afternoon.. tore down, tried to fold back up and put them away without any ill effects. They seem pretty thick and durable but even if they don't last that long they're only 11 bucks and some change. 3 was not enough to properly cover the 8x8 dome tent so I'm going to grab 2 more and be set. I will probably have to pick up at least 1 more for my emergency kit as well. These would be extremely handy as I can't see a normal mylar blanket lasting more than a night or two in a "bug out" situation. And you absolutely need that ability to reflect heat from a fire when it's brutally cold.Edit - The only problem with these is that it makes tent camping a little inconvenient in terms of keeping the environment at a steady temp. If you have these surrounding your tent and run a heater. it'll be toasty and warm in there no matter the outside temperature in a matter of minutes.. soon after it will probably be unbearably hot.. However, turn them off and it will be back to the ambient temperature in 15-20 minutes. It is far more wasteful but it makes for a much better night of sleep if you don't use them and just run the heater all night. I'm not really calling this a negative. it just is what it is. This has been my experience in slightly below freezing temperatures (and above). I'm not sure they make purely propane powered (indoor safe) heaters with a thermostat that doesn't require electricity (other than a battery) but if such a thing exists that would be ideal.

I love this!As y'all probably know we frequently lose power for days here in Texas, I have been using this blanket the last few years during times I have to sleep without heater at home and below freezing point temperatures outside.This works so well that sometimes I even end up getting sweaty!

It's about as sturdy as a normal blue tarp but this one is orange (for high-viz) and shiny (to reflect radiated heat). Grommets are nice and double layered.Could make a nice groundcloth for a tent, if the tent was the right size.

Meow! I bought this out of guilt and worry that my perfectly fine feral cats might get too cold when the temperature dropped down into single digits this past winter. I used it as an outer layer over their most likely already warm and definitely cozy fort. Maybe it was the heat radiating off this extra layer of protection or maybe it was spending 11 dollars to feel I had done all I could but I swear right after adding on this layer I felt warm and my guilt melted into a puddle right there on the garage floor. The cats had no complaints, they settled right, promptly ignored me and curled up for a nap. Lucky for them the power did not go out because I suspect I would have found I could get over my guilty conscience rather quickly and confiscate it for my own warmth! It is well made, sturdy, looks brand new after several months of use and is now part of my emergency kit. I also plan to use it at the beach with some tent stakes to hold it down (the corners are reinforced and have good quality grommets). It would be great as a wind shield, ground cover, extra warmth layer or tent cover for camping as well. I plan to buy a couple more before winter!

These tarps have proven to be useful & durable! I'm using them on either end of our pop-up camper, silver side up, to reflect off the sun & heat so the camper A/C won't have to run so long or hard and draw so much power to keep the inside cool. They've been great! I use a few bungee cords with hooks to keep them in place and we've had no issues after continuous use over the last month.UPDATE: They only lasted one season! They started to rip & tear around two months of use.

I haven't had the opportunity to use this yet, but unwrapped it and it feels well made, thick and sturdy. This is unlike the thin foil-like "blankets" in my emergency bag. I plan to mainly use to deflect sun when my car is parked. I will update review when I've used it for that purpose.

These are really nice size blankets. I got these to use for cold weather camping for a Scout training I had to take. I put one of these blanket under my tent on top of a tarp and one inside my tent on the floor. I had a third blanket to put over my tent but ended up not using it. It was rainy, windy and around 34 degrees in a 3 season tent (that really was more like a warm season tent). Putting these down under the tent helped to hold the heat in. And using it in the bottom of my tent helped a lot. They're a little noisy (there was no being quiet putting this down at 11:00 pm so sorry to my tent site mates) but using this under my foam interlocking blocks helped so much. I used a cheap bed roll, a more expensive bed roll and a self inflatable (I can't say it really inflated as it didn't seem much different to me when I took it out of the bag but it was supposed to inflate) bed roll and didn't even feel the big root that I know was right in the middle of my tent. Putting my 0 degree sleeping bag spread out and then my -35 degree bag down, between my cheapo hand warmers and insulated underwear and socks, I stayed pretty warm in a tent whose top was made of mesh. I will be using these again and again on any cold weather camp trips I make. I can't speak to the durability as I just purchased them and haven't really used them hard but they seem like they will last for awhile. If anyone is on the fence, I recommend these blankets.
