Yooshare Heated Vest Far Infrared Temperature Adjustable Heating Vest Warmer Underwear Free Size (S~XL) Healthy Waistcoat Heated Jacket for Men and Women Back Pain Relief （Battery Not Include）S~XL

The price to performance ratio here is excellent. This vest does do the job and depending on the USB battery pack/juice pack you pair with it - it lasts a long while. As some of the other commenters have pointed out the material seems to stay warm even when it's not on. This is very true I really don't know what the material is but it works amazingly well to seal in the heat (and body heat!). NOTE: it does only heat the back but I found this more than sufficient. Props to the Chinese engineer that threw this together! I am a 6'0 189lb man and it fit me perfectly.Very good product for the cost! 5/5 from me I would recommend to anyone in the heated garment market.

Works nice. You need to grab your own charging block. I just hit a Fivebelow - a standard Apple charging block will not work. It’s a little bit small for a larger man.

Absolute scam. I bought this for my nephew and it doesn’t work. I’m so pissed off that I spent 35 bucks on this piece of crap. I want my money back, but now it’s too late to return it. DO NOT BUY THIS. It’s also very small and cheap looking and feeling.I repeat DO NOT BUT THIS.Give me my money back.

I purchased this item as I was seeking a minimal/thin vest that wouldn't be too bulky. This seemed to be the slimmest of all on Amazon, however it is slightly thicker in person than it appears online. Did not test the battery as the fit was way too big. If you are a woman size medium or smaller, this will be too big for you. Even with the handy Velcro adjustablility, I couldn't get this vest tight enough for a good, hugging fit for heat transfer. However, for men this would be a great option. Seemed well made.

Got it for my brother because he loves hiking and spends a lot of time outdoors. The size fits him perfectly, but if you are wide in the chest, might be too tight on you, so it's not like "one size fits all".Rather than that, everything is great, matches the description. Instructions are pretty clear on how to use it. Got the power bank for it at Walmart for 10 bucks.Would make a great and rather unique present for outdoor lovers:)

Worked for a couple months and now when powered it only lights up button a moment and that's it. Does not last.

Works as intended, keep me warm . I just wish the pocket for the battery is deeper so the battery can stay securely

I purchased the vest for my husbad because he works in the cold. Although i myswlf have not tried it....i gave him the 20 questions...It actually holds heat even when not turned on. Very easy to adjust size although it does tend to ride up. Temp setting is easy to adjust and kept him warm all day. Does not cone with a power pack but thats ok for the price it is still worth it. I recommend this highly
