“Works well & heats up quickly. My husband works construction & this vest gets him through the cold winters. I ordered an extra battery right away so he can use the heated vest all day long! He loves it! He normally wears an XL. I ordered a XXL so he could wear it over top of his quilted hoodie, long sleeved shirt & thermals. It fits perfectly.”
“I bought this to have a second battery to be sure I got full warmth out of my vest for 12 hours a day. So far I’ve not had to change the battery out while in a hunting situation. Very pleased with the product.”
