CamperVan_Man: Could you recommend any non-powered cooling blankets? The only ones I am familiar with are the hospital ones that require power.

Greetings Spiff!
Amazon appears to have the NASA ones, and I love mine. That being said though, I do not know if they are identical to mine. Years ago, before retirement, my Aunt & Uncle both worked for NASA, and mine were gifts from them.
Prior to these I had a thermo electric one, and I would NOT recommend them. It was great when you went to bed, but a few hours later you'd wake up freezing. It had no thermostat, only heat or cold, and in either direction it was heaven for a couple of hours, then hell, either frozen over or fire & brimstone...

These "LOOK" the same as mine, and they say they're NASA.
It's hard to put a price on comfort, and I think the guy's pricing these are taking full advantage of that fact. There may be cheaper alternatives, someone once suggested "Medical Cooling Blanket" as a cheaper alternative. I haven't done a search for those.
These NASA ones work perfectly for me, seems they're designed to optimize your body temperature, regardless of the surrounding temps. Mine seem to work REALLY well.
My Aunt & Uncle also gave me several pairs of NASA long johns and tops, and as silly as it sounds, you can wear them when it's 120° out and stay cool! If I wind up in the desert in the summer and have to go outdoors, I'll put on my NASA long johns, and everybody HAS to think I'm nuts... Even have NASA ski type masks that work in the summer too...
I don't know what their secret is, but it sure works. I heard that the Frog Togs guys used to work for NASA too. Don't know if that's true, but I have heard good things about their products, even though I have no first hand knowledge.
Cheers!
