I ordered these as a 'fix' to summer's excessive heat. I put these over my bedroom window cut to size and double layered. I also put two of them over the 'fixed' part of my balcony window... and cut to size on my balcony door. It has reduced the heat in my apartment to the point where my air conditioner is not struggling with the sun's heat. And ...I work night shift. The added bonus is how much darker my bedroom is with the blackout curtains combined with the cut to size sheet. If your suffering from the heat, or just want your window a little darker I can't recommend these enough for that. Thankfully, I've not yet needed the extras for any kind of emergency. But, if I do, they've already proven their ability to redirect thermal heat.
You can't beat these ultra lightweight life savers. Each tucks into your pocket while hiking and could save your life! I keep two in each car and during a snowstorm last year I was stuck on a country road for five hours without power. One of these kept me warm the entire time.
This pack of 10 emergency blankets is probably the most cost effective way of adding them to you your kit.
Emergency blankets are a one time use Mylar blanket that uses your own body heat to keep you warm. They have variety of different uses such as shelter and signalling (for those who hike/camp back woods).
I personally have these in my first aid kit in my car (5 in total) incase I come up on an accident. I have another few in a small survival kit in my car (live in Canada, times where you’ll be quite a distance from a population). I also carry 2-3 with me hiking incase of emergency. Since they weigh next to nothing it’s an easy justification to carry them with me.
I would highly recommend everyone keeps a few of these on them in the outdoors and even in their car.
Sometimes you see things like this in other people’s homes and cars and think, for a split second, that this person has their act together. This person is an adulting wizard!
Now you can be that person!
Get these. Put them in your apartment, your car, your emergency kit, your camp kit, your hiking backpack, your atv, your snowmobile, whatever. Being cold and in shock is not fun.
Oh and while your at it, drop some coin on a decent first aid kit, get a good quality fire extinguisher or a fire blanket for your kitchen. Familiarize yourself with these magical tools that will save you, your neighbors and your damage deposit when (not if) you get distracted and forget that your bud butter is cooking away on the stove.
Purchased these to reflect light in my home made plant starter. First one I used ripped on me, but luckily you get 10 for a great price, so no reason for complaint there. A lot bigger than I was expecting and they work great for what I needed them for! I threw a couple in my vehicle for emergencies as well... you never know!
I've been using these in a heatwave to reflect some of the light/heat in my apartment. They are economic and reduce the internal temperature in the apartment by a few degrees. I don't find them durable as blankets as they rip easily and you can see the reflective surface rubbed off in the fold. But for the cost, they do a great job at reflecting heat in old apartments and aren't completely opaque so provide a bit of light as well.
I bought this for 2 reasons. To keep a few in my car and to add as a deterrent for my car to get near the Christmas tree. My cat is legit so scared of the sight and sound of the crinkling. It works way better than foil paper. I’m sure it works great as an emergency blanket, but that’s was not the intended use of this purchase.
I used these as solar shade on my tent at a burningman regional where we don't have crazy winds (don't take these to the big burn, it's instant moop.) Held them on outside tent walls and roofs with magnets. They performed very well, kept the inside of the tent cool and dark. I could sleep in for 2 extra hours more than the first day I didn't have them up.
They're very thin and tear easily so pretty much single-use.
Now have one up on my bedroom windows for the same purpose. See how long before the plastic degrades...
