Mylar heat blankets are very effective, especially for their size and weight. But they crinkle loudly.

Does anyone have personal experience with a reflective blanket that is quiet?

(My searches online and on YouTube discovered some claims, but no confirmations)

I guess another way of asking is "Is there such a thing as great reflective fabric that isn't crinkly?" Thanks.

    These heat blankets are intended for emergencies, not as replacement for a sleeping bag. If you just cheated death, the noise is the least of your problems.

    Similar to @PMF's comment, why does the noise matter? What use case do you have in mind where the noise is an issue?

    As someone who travels light when cycling through the night, but might want a nap, I can see the appeal of an extra layer of warmth and wind protection in case clothing isn't enough. I actually bought a mylar foil bivvy bag for one trip when I expected 2-4 hours rest waiting for an early ferry, with nowhere to camp and no hotels with check-in in the small hours. When wild camping isn't allowed, using "emergency" gear to keep warm while "happening to fall asleep" during a "rest" is very different from setting up camp

    ... So to make the most of that limited sleep time, probably in not a very comfortable position, it might conceivably be nice to not rustle at the slightest breath of wind

Silvered tarps are quieter, but still far from silent, as well as being heavier and bulkier. But they're also far more reusable than foil blankets. I have one of a similar size to mylar blankets that I use underneath me, and a larger one as my tent. They certainly reflect heat, though probably less than the foil blankets. On the other hand they would wrap round you better.
