Venture Heat Women's Bluetooth Heated Shirt with Battery Pack Included - App Control Thermal Long Sleeve 7.4V

These have done a great job keeping my wife warm and able to enjoying being out in the cold for longer. Great customer service as well. The battery melted during the first charge right out of the box and as soon as I contacted customer service they immediately shipped me a replacement battery.

I wanted a heated undershirt for camping and cold winter days. Problem is, most out there have the front heater on the chest. As a larger chested individual, that is really not ideal. When i found this one with the heater on the lower stomach i thought i would give it a try. I have to say, it performs way better than i could have dreamed. Heats up instantly! the power bank it comes with is ok, idk if they come in different colors but mine is a cute teal. lasts nearly exactly as long as stated. i also got a 10k and 30k for it so it lasts longer and so i can switch them out. if you're near a charging cord you can also charge while you're using it (as long as you dont mind being attached to a cord). the poser button on the sleeve is padded so that it doesn't irritate when you cycle through heat settings. I love that it doesnt have to be on high to be warm. even low is warm enough for chilly weather, medium is perfect for me, just the right amount of toasty. High is great for when you first step out of the house into the freezing wind and snow until your car heats up enough. I was worried i'd be spending a ton of money for something that may not work well but i LOVE this shirt. Edit: Also great for cramps!

Fit: Slim, but fabric is stretchy so you can layer another top over it.Included battery: Small but around 4 hours at medium level. Note that I am using a larger battery pack that I had on hand, but it's too long for the pocket. if you try to force the pocket to zip, it will interfere with the USB power. So, I let it hang out and zip only a corner over it, so it will stay in the pocket.The heating elements are right next to the skin, and the fabric is thin, so if you use it on high heat, wear a Tshirt under it. I keep it on Medium settings.

It's my first winter up in Maine so I've looked to purchase a heated everything to keep myself functional. I started with this base layer as the reviews were good and it looked like something I could wear to work every day comfortably. I just took the battery pack off the charger at 11am and by 11:30 it was off and dead from a full charge while being used on medium heat. I've seen reviews where full temp should last 2 hours but I've never gotten more than 45 minutes out of it while being on low. For the price of the product, one would think the battery would last longer and I wouldn't need to purchase another $40 battery to keep warm for more than an hour at a time. And be careful when it even comes to that as it is temperamental about the type of portable battery it takes. I tried to use my Anker and the light would flash once and turn off. Overall it's very comfortable and I would love it if it was actually a heated shirt. At this point, it's just an overpriced zip up shirt.

Fit fine on the top, but tight on the bottom. I usually wear a medium, on occasion a large. I am pretty proportional and have not run into this issue with tops before.

This is a decent shirt. I am only 5' and 115 lbs. I ordered a medium as I do not like tight fitting shirts. I did put it over a short sleeve light material shirt and the fit was good. I had it on high and it did emit heat for two hours. However, maybe because it was over a shirt I did not feel it was giving off as much heat as expected. I cannot return as I removed the tags, otherwise I probably would return and ask for a refund.

After reading the comments I decided to purchase a size larger then I usually wear. I wish I hadn't. Because I'm short and the shirt is extra long I'm not getting much benefit from the lower heating elements. This is on me for ordering the wrong size so I did not knock the rating.Read the description carefully, I was hoping for a 6 hour battery life. I got 2 hours. When I re-read the description I saw why. 6 hours is only if you use it on low (which is really low and personally not much of a benefit). I have it on high and am getting the 2 hours they advertise. Again, my fault so not knocking the rating.The material is high quality. It's a great undershirt and I would buy it again (but if I had the option to pay more for a longer battery life I would).

The battery life sucks, will not stay charged. Having to charge it every other day. Very frustrating. When I want to use it the battery is died. I feel like it was a waste of 139.00 dollars.

Very nice fit and heats up well

Battery dies after 10 minutes

I took one size smaller because the heated elements need to be close to your skin for you to feel the heat. Big heated elements, but battery life is disappointing (2hrs at max heat). I bought another stronger power bank (20.000Ah) to solve the problem when I spend the entire day outside. Very satisfied overall, I will definitely recommend this product.
