I have been drawn for a lottery deer hunt on Feb 3, 2018, in northern ohio. I cannot take a portable blind or buddy heater. Because of medications I cannot stay warm while still hunting no matter how many layers I wear. I can't walk all day to stay warm either. The disposable heat packs and UA 4.0 base layer only work for me down to 25F.
I am looking at battery powered heated vests and base layers. I would like to hear others experiences with these systems.
Thanks,
BB
