I used to have Wife's.
Bung years of yore ago they had as advertised Electric Blankets. But they 'IMO' sorta disappeared or took a dive and where then called?
"Warming Blankets" and where better then nothing but. Here's what I did when my bones in diffrent places got to bother me badder in the winter then summer. I got one of these Electric "Heating Shoulder Pads" that's about two and a foot wide and 4 foot long with four settings and that one worked so well?
I got another one and when it gets bone chilling BRRRRR
I run both length wise foot to nose and fire those suckers up and set em where I wont to and while not a wife, they don't end up with half my Stuff COOL.
