Reddit reviews Swiss Safe Emergency Mylar Thermal Blankets (4-Pack) + Bonus Signature Gold Foil Space Blanket: Designed for NASA, Outdoors, Hiking, Survival, Marathons or First Aid

Is there anyone in Tokyo that could sponsor OP one of those thermal emergency blankets?

They fold up very small, so you wouldn’t have to worry about carrying it/them. You could lie them on the ground, or over your blankets/cardboard. They reflect the heat back onto you instead of outward. Also good for keeping rain out.

I have a few solutions to this as i myself have gone to the extremes on sleep deprivation at lib. Here are a few game changers that made a world of difference.

1. Your tent. We found that righ as the sun comes up sleep is almost impossible due to light and rockstar heat. We got a bunch of those emergency thermal blankets and lined the exterior of our tent almost entiely in them. This both blocks light and a huge amount of sun heat. They make it seem like air conditioning compared to not using them. Packing tape works very well on holding them together and allows you to customize their shape to fit your specific tent. Another tip is to sandwich or layer them between a fabric material to dampen the noise they make with the wind as they move. Those mitary guilly style camo covers work well too. You basically want to hold them down as well as possible to limit how much they move to eliminate the noise they make, which is like tin foil.
   Be creative and innovative with these as they can look really cool too! Your tent will be dramatically more comfortable all day.

   They come in multi packs to save money. Also if you have extra, im sure your neighbors will appreciate it greatly if you donate a few. The only drawback is the noise, so ensure you address this. Installing them on the inside of your tent is also an option.

   Ill keep this short, they just work, period.
   
   
5. Cool as LIB!

   We discovered these and theyre awesome! We wet them down at the water stations which are everywhere throughout Lib. They feel amazing in the sun and in a wierd way are kinda fun, idk. Lol
   
   
6. Bring vitamins! I recommend D3, ZINC, B COMPLEX, AND FISH OILS.
   Make sure you keep these all cool and dry.
   
   I recommended a cooler scenario in another sub, but ill repeat it here.
   
   Dry ice in your cooler is the best way to refrigerate all weekend that i have found, minus actually having a refrigerator.
   
   Tip: careful with dry ice as it can burn you and mess up your cooler if not prepared properly. Wrap it in brown paper to prevent direct contact with the sides and bottom of your cooler. Also, if you put actual ice around the dry ice this works too. We got a solid 3 days of awesome cooler performance this way. Cover your cooler during the day with the above mentioned mylar blankets for even better performance.
   
   
7. Protein power! You need nutrition if you want to rage like a rockstar! Many flavors and its super fast and simple to prepare. I use mp combat protein, works well and tastes great!
   
   
8. Bed/air mattress. One oddity we found with our air mattress. At night the ground and ambient air temp drops a bunch on some occasions. So the air inside the mattress cools as well which made for an extra chilly experience one night. We insulated the bottom and sides of our air mattress with a fleece or similar blanket which helped keep our body heat inside the mattress.
   
   
9. Feed me! Bring good healthy food like apples, avocados, bananas, pita bread, peanut butter or almond butter. These are delicious and full of proper energy. Keep junk food to a minimum, but dont eliminate it, because well, sometimes cheese its are bomb as hell! You just dont want to be weighed down by garbage. Tip: the acai warrior bowls at the food courts are legit! And, try the poutine for breakfast! You wont regret! Also we found that Mountain house freeze dried packets are a convenient and awesome way to chow down. You'll need hot water for some and regular temp for the cereals and desserts.
   
   I hope this helps. Unfortunately I can't be at LIB this year, so this post helps me cope with said situation.
   
   I have many other pro tips if anyone is interested so hit me up
   
   Love you LIB!
   
   

A lot of this would depend on the situation, but assuming that this bucket would be all that I'd have to live on for 72 hours...

• Line the bottom with 1 liter bottles of water. I'd want minimum 6, preferably 9. Ideally I'd also like a Sawyer Mini Water Filtration System. That's a chunk of the budget right there, but it allows for refilling of water bottles from a lot of sources which could be valuable depending on the situation.
  
  
• 3 Mainstay 2400 Bars. Walmart sells them for less than $5.00 each. I'd add in a couple of gallon sized ziploc baggies to boot because they aren't individually sealed. Probably wouldn't be super pleasant to eat only these for 3 days, but there's zero prep involved and they get the job done. Maybe get an extra one to try out ahead of time to make sure they don't do anything funny to your stomach.
  
  
• Probably some mylar sleeping bags and several blankets. Then add in 100' of paracord. The blankets and paracord would allow you to provide shade or insulation as needed.
  
  
• Two lighters (one for backup) and a standard pill bottle filled with cotton balls smothered in vaseline (tinder for fire, cheap and efficient).
  
  
• Hand sanitizer (also works as a fire starter), sun glasses, chapstick, and a neck cooler (also sold for <$5.00 at walmart). Add in a handkerchief that you can soak and cover your head with. You can probably find more clothes to put on if it's cold, but it's hard to deal with heat, so that's important to take into account. Add in a small roll of duct tape as well.
  
  
• A mini-med kit. To keep it within budget I'd mostly use what I have at home. Add bandaids, gauze, lots of ibuprofen, lots of multivitamins, sinus meds, pepto tablets, sunscreen, and allergy meds. Splurge and pick up a decent sized tube of antibiotic cream. It's not comprehensive, but this is a 72 hour kit. Hopefully that would mean more being concerned with comfort than full on survival.
  
  
• A locking folding knife of some sort. Make sure it's sharp as a razor before putting it into the bucket. Doesn't have to be top notch or expensive here, but does need to be sharp. If room permits and you have one already, also toss something Ka-Bar like in. Something that has a little weight to take a branch off, but also is sturdy enough to assist in minor digging.
  
  
• If you have them, toss a pair of wool socks in. No matter the weather those are always good to have. Otherwise, just get an extra pair in there. If the weather is cold you can double up. If it's hot you can change them out to keep your feet fresh. That's important.
  
  
• A spare phone charger. Chances are there will be electricity somewhere, and phones are absolutely important. Worst case, get a $10 cheapy, test it, then toss it in.
  
  That's the necessary stuff for a 72 hour kit imo. It covers shelter, food, water, warmth (and cooling), and as much security as you can get within budget. It should keep you comfortable for a few days if you have to grab it and move toward a place where you cannot be assured of any necessary resources being present. You can fill gaps with things like gum, hard candy, a good book you don't mind re-reading, as well as anything else you might need to keep yourself occupied.

Thank you so much, I really appreciate it!

as for blankets, would it be better to go with this versus this?
