I recently received quite a few reflective bubble mailers from a friend. I have seen people using them for holding in the heat while freeze-dried food re-hydrated. Has anyone used them for anything else? I am not sure if the could be used for sleeping pads. Has anyone tried them for that purpose? I have some that are about 8 x 12. Would they make a good winter layer under a non-insulated air pad? Any help would be appreciated.

years ago I tried this. I punted on the idea. I found that are warmer and more comfortable options for the weight / volume. If you were combining them with an uninsulated pad, you would want them on top of, rather than under, the air pad.

Two problems:
The bubbles pop
You can't compress them

Otherwise, yes, they can work, but they are not as warm as other options as the air can circulate inside the large bubbles.

This is a picture of what I am talking about, along with a lighter for scale. The reflective coating is on both sides, and the bubbles seem pretty tough. These look like what I have seen people use to keep their food warm when it was rehydrating, but I'm not sure. These are used to transport medical supplies such as insulin.

If it packs small enough, I would gladly try this on a spring, summer, fall trip in between myself and my pad.

Must do some good, its encased air and has reflective properties.

I use the ordinary non-reflective sheets of bubble pak sometimes in summer. I have one of the large box/rolls of the pink stuff. I don't expect to get much insulation out of it, but I use it as a ground sheet that maybe has a tiny bit of insulation.

Some of this stuff has large bubbles, and some has small bubbles. If you put your elbow down on the large bubbles, they tend to pop, so I use only the small bubble version.
