they are very convenient to carry I carry an extra for my vest and one for the pants
Overall, the additional battery I purchased charges in a relatively short period of time and lasts quite a while in my vest. I have not run the vest on its highest setting because I've only worn it while on the move, but I believe I can easily make it through an entire day in a tree stand with just two batteries.
the vest is awesome. had some trouble with the battery which they replaced. All my messages were answered promptly and new battery was sent out quickly with no hassles.
I used PNUMA at minus 7 while plowing the driveway on my tractor. 90 minutes later still comfortable on the tractor. A best Purchase product for the vest and long johns.
Unfortunately have not had opportunity to try outdoors.Big snow goose trip shortly. Coyote after that. Will have better results in couple of weeks. Fit was nice and snug as ordered
My hands never got cold. Did not need gloves even in 26 degree weather. The warmer worked as described and i only suggest getting extra battery for all day sit. In high winds and rain my hands were nice and warm.
