It's an insulation material that they put on sheds and houses. If you put your hand against it, your hand starts to warm up instantly, even if it's cold. I think it might have the same material as in "space" blankets that they advised you to carry around for a survival kit in your auto, a few years ago.  Then it has the bubbles on the other side also or sandwiched in between, like the stuff they send wrapped around things in boxes.

No, it doesn't breath.

Guess my cows weren't very scared of anything like that. 'Course if they were real good mamma's, the calf probably didn't need the blanket! :lol:

I've stuck it on a few at night when it was wet and blowing out. When they warm up and dry off inside of it, they get up and the ol' cow tears it off or they walk out of it. Don't think I ever had to take one off, tho' I picked up quite a few and used them again. Little duck tape and BINGO, good as new!  :lol:

In case you can't tell, I'm kind'a cheap and look for cost saving ideas all the time. I like to spend my money on wine, a woman and fun and just HATE to waste it on foolish stuff! :wink:
