I would go to Big 5, REI or whatever is your sporting good store and get an emergency blanket. Not that thin foil crap.
A real one. They are very thick and durable, work perfect as a windbreaker and will definitely keep you warm.
I tried one in Lake Tahoe, at 10 degrees, worked great. Only reason I didn’t stay out all night is a cop wondered if I was okay. Told him I have a room just testing this blanket.
He asked me for I.D. and I said it’s in my room, so we went to the room showed him my I.D. and my friend said “He is an idiot. He is always testing everyting he buys. Thinks he is Survivorman.”
Cop asked how long I had been out there and I guessed about 5 hours.
The thing worked great and I was warm and dead asleep when the cop woke me up.
Anyway, reminds me, I have to go and get a replacement. I put one on an accident victim last month and forgot to replace it.
I will try to remember to let you know the brand and cost. But, it will be way cheaper than some specialty sports gear or even something like a Columbia Ski Jacket($300 and up).
I will post back to you in a few hours.
I had one of those sandwiched between some wool Army blankets when I was in Germany. Used them to replace my sleeping bag. A lot less weight, water resistant and warm as anything.
Might have to construct something along those lines. But it sure would be nice to find one already made.
BTTT GET the replacement and help this guy
