light weight and easy to store in my base layer, and will help to keep it running longer, a win win.
Spare batteries are a must for long outdoor days!
It's great having extra battery
I’m getting an average of five hours on medium per charge the fndn products are fantastic

these batteries work just as noted on the FNDN web site. small in size and holds the charge for said time.. I will continue to shop the FNDN store
Has been a great base layer. Use mine almost everyday. The heat on my back id compare to my heated seats on my car. Very nice. Even without the heating the shirt is still made very well thick and comfortable. Just ordered the socks they definitely have my business

High quality products
I bought the Baselayer top , I work on the flight line and this is perfect for those cold windy nights. I stayed warm all night long. Highly recommended.
