My wife and I have been building our home for the past twelve years, all by ourselves, and a Panther Vision Powercap has been on my head the whole time. It’s four miles on top of a mountain surrounded by seventy-five miles of state forest, it’s way out there. There was one time we went up in February. We arrived at 11:30 at night in two feet of snow and got stuck a hundred yards from the house. It was -22 degrees and none of the lights we brought with us were working, except my hat. It got us inside the house where I was able to start a fire. I made two trips to the truck and back just with my hat. It was truly a lifesaver that night.
