heater body suits??
Has anybody tried one of these heater body suits. Saturday I had all my cold weather gear on (14 degrees +22 mph wind) and had to move out of a tree stand to a pop-up ground blind. I lasted for about 6 1/2 to 7 hrs. but that was it. The cost of those things are about $300.00 (I got that tied up in cold weather clothing) Is it worth it?
