[Disaster Prevention] Experimenting whether you can sleep outdoors in mid-winter with Daiso's "thermal aluminum sleeping bag" and "disaster prevention storage air mat."

Even if you prepare food and water in a disaster prevention bag, it is surprisingly easy to overlook cold weather measures. Will you be able to survive during the cold winter? I actually tried out Daiso's "Insulated Aluminum Sleeping Bag" and "Emergency Storage Air Mattress".

Because it’s Daiso, two items together are only 1100 yen

There have been a lot of news about earthquakes, so I checked my disaster preparedness supplies again. I also prepared for "cold weather measures," which I hadn't thought about at all during the summer, in order to enhance the quality of life during evacuation.

What I bought is Daiso's "Insulated Aluminum Sleeping Bag" and "Disaster Preparedness Air Mat." I tried these out to see if they would be useful in case of an emergency.

The air mat with a pillow is surprisingly comfortable.

The "disaster preparedness air mat" is 195cm long. The reason it is slightly longer than a typical outdoor air mat is that the ends are designed to be rolled up to be used as a pillow.

The size seems to be spacious even for men, but when it comes to preparing for disasters, what concerns me is the time it takes to inflate it. Well, at this size, it seems like it would take at least 10 minutes to fill it with air... The package also mentioned that a separately sold air pump can be used, but it might be difficult to bring a pump during evacuation when I want to reduce baggage as much as possible. So this time, I will intentionally fill it with air manually.

I blow air into the entrance continuously. At first, it felt like there was no sign of it inflating, but as I kept blowing air without giving up, the mat gradually started to inflate.

Air injection is complete! It surprisingly took only 3 minutes to inflate by mouth. During the process, I took a short break to catch my breath and checked how well it was inflating, but I wasn't rushed, and the mat was completed faster than I expected.

When I tried lying down on it, it was resilient and more comfortable than I imagined. It also seems to be good at reducing the chill from the ground, making it comfortable for winter evacuations or camping. When the ends are folded over, it becomes a pillow that gently supports my head. With this, I feel like I can rest my body with peace of mind. However, it seems to be weak against sharp objects and friction, so it would be best to lay a blanket or something underneath when using it on the ground.

The aluminum sleeping bag also seems to be warmer than expected.

It's quite cold with just the mat, so I'll make sure I can sleep with the "thermal aluminum sleeping bag." The crinkling noise is a bit loud, so it might be a good idea to spread it out in advance when using it in shelters, etc.

However, once I get inside, the cold air is shut out and it gets really warm! I'm wrapped in a warmth that feels like being in a blanket, or rather even warmer than that.

The outside temperature at this time is 9.5℃. And inside the aluminum sleeping bag, the temperature rises to about 20℃. This is evidence that the aluminum reflects body heat efficiently. Since there is no cold wind hitting me, I felt warmth beyond the measured value.

When using it in colder environments like mid-winter, it seems that adding a blanket or sleeping bag inside would enhance comfort even more.

The inside of the disaster prevention bag is also neat.

After using, just let the air out of the "disaster prevention storage air mat" and fold up the "thermal aluminum sleeping bag." It can be compactly stored, so it will fit neatly inside the disaster prevention bag.

Both combined cost only 1,100 yen, making it a great value! I suggest preparing one for each family member to be ready for any potential evacuation situation.
