DUKUSEEKHeated Vest, Men's Fishing Vest, USB Charging Warm Heated Fishing Vest for Men Outdoor (Battery Not Included)

I got this as a gift for my brother and he loves it but it didn’t come with the battery! So don’t expect to be able to wear it out of the package.

I like how the sides can be zipped off and added or removed to account for if you are wearing more layers underneath, or if you are a little bit wider than some. As far as the battery life, mine did not come with a battery, but I bought a power pack separate and am having no problems with it lasting all day.

Got this to take fishing in northeast Idaho. Fall and spring time the temperature swing is durastic and this product fits the bill perfectly. Super cold in the morning, turn on the heaters to stay toasty warm, as the day heats up, click em off, and you don’t end up sweating your butt off. As the evening comes on, click them heaters back on. I used a jump starter battery pack that hardly used half it’s capacity all day long. The side extensions were a nice surprise. I can throw a hoodie on under it and use an extension to keep it from being overly tight.The extensions can also be used as leg warmers by the little ones. 😂
