Deceny CBHeated Vest for Men Women, Heated Vest with Battery Pack Included Rechargeable, Electric Heated Jacket for Hunting Camping（Dark black,XL）

This vest has heat in all the right places. Haven’t used outside but use for work in factory. If I get to warm I can turn off heat and the vest will hold heat in for a while and is even warm when not using the heat. Battery last an impressive amount of time as well.

It barely fits enough to move around. I recommend buying next size up
