VEST when it works

Back up battery - Piece of mind

The original battery works great, but for long, cold sits, it's great to know I have back up. Also, it has a USB port in case you need to charge your phone while out in the field.

extra batteries

you will want to order a second battery. They work well. First thing I pack for deer hunting if it's cold!

Heated vest and battery

Love the heated core vest. I wear it every chance I get. Just needed another battery to keep me in the field even longer.

Tom Weix (Antigo, US)
Vest and battery system

I like the comfort of knowing when I get a chill after sitting in my deer stand or on the Lake for 3-4 hours I can count on my Pnuma heated vest to take that chill away. I turn mine off and on depending on the time of day because you will only get heat for about 2 hours on high so I purchased another battery just in case one runs out of juice.

I purchased an extra battery works well and happy with purchase
