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 am using this as my sunscreen on the front window of my car. These hot Texas summers are rough on the interior of my car and this cover does an excellent job of blocking the heat and suns rays. It was so hot before this, we couldn't even get going till it cooled off some. I attach it with some magnets and put it over my window and now when I take it off and get ready to go, I can get in the car and go. It seems to be good material and has been holding well up so far.

Good tarp overall, decent thickness and the reflective side works brilliantly for keeping a tent or car dark and cool while camping. The only problem is the construction quality, after only one night of use using bungee cords under light tension the corner grommets were ripping out. By the second night all 4 bottom corners (2 tarps) had lost their grommets and were being held by only the nylon reinforcement around the edge. Had there been any serious wind or a need to keep real tension on the tarp the corners would certainly have ripped out entirely. I was hoping these would be reusable and last me at least a few camping/festival trips but due to this they're only really viable for single uses.

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.

This is basically a somewhat more durable version of a single layer mylar blanket. This survival blanket is considerably more durable, tear resistent, and useful. At about 2/3 of a lb, it is heavier than a single layer mylar, but well worth the weight.I use it as a ground sheet under the tent, as a picnic blanket, as a seat during hikes and as a rain tarp for shade. With so much multi-use flexibility, this is one of my must have backpacking items and has been for about a decade

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.

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!

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.

La uso como base en mi tienda de acampar, aísla el frío y da una protección adicional en caso de lluvia. Los materiales son gruesos y resistentes pero ligeros y ocupan poco espacio en la mochila

Utilisé en hiver dans la tente pour couper le froid du sol. Parfais, elle coupe bien le froid pour renvoyer la chaleur corporelle vers le haut. Ne pas s'emballer à l'intérieur, garde bien la chaleur et transpiration à venir si on ne laisse pas s'aéré de temp à autre.

Solid and sturdy, performed well. I used it to actually reflect the sun off of my tent and it kept the temperature down. Will be great to have for outdoor trips.

I've hung this blanket on the east facing window of my office to reduce the amount of heat coming in. The sun is strong enough to heat the window frame to be uncomfortable to the touch, so blinds just weren't cutting it.It blocks a lot of the light from coming through, and the reflecting side keep a lot of the energy out. It has made a noticeable difference on the room's temperature.However, the stitching on the border isn't great, and has come loose in several places. Not important for my personal usage of this product, but worth noting.

Très bon produit bien isolant, léger et amples, les attaches sont un plus, ( je l'utilise sous ma tente pour l'isolation du sol et les intempéries car bien étanches, très solides je l'utilise régulièrement, je conseille ce produit car de bonne facture
