AnoopsycheElectric Heated Vest, USB Charging Heated Jacket for Men and Women 3 Levels Heating for 8 Hours, 5 Heating Pads, Heated Clothes Jacket for Warmth, Outdoor Work, Ski, Hiking(NO BATTERY)

I bought this to put on under my gear when I ride my motorbike in the fall or when I am snowboarding or snowmobiling. It is super thin but has a decent metal zipper and will fit under any garment. With a 10,000 mha battery pack I get 6-8 hours on high which is too warm. I run it low or med snowboarding and good all day with the one battery pack. On the motorbike in fall I will use my 20,000 mha battery pack and run it on high continuously I don't know how long it will last because I never ran out of power even on an 11 hour ride. This is a utility piece don't buy it for fashion because it is not that, you buy this to keep you warm and it works well.

I needed something like this for a long time, even though I dress warm with many layers during the winter, sometimes it's not enough. But this heated vest will help immensely, I plan on wearing it under my jacket on the coldest days outside.I tried it out right away when I received it with my portable battery pack, tried the max setting first as that is why I had bought it initially and wow did it get warm very quickly. In fact, it was so warm that I had to turn it down, but that's what I wanted, it's good to have the option to go very high or if it's not that cold outside maybe set it to low or medium and get more out of my battery's charge before recharging again.As an added bonus it looks really nice, very stylish, I didn't expect the vest to be so fashionable but I was pleasantly surprised.In terms of size, I purchased the Large, I was considering the Medium but because I was planning on wearing it over dress shirts/sweaters in the future I went for the large. I'm 5' 9" and 170lb, the large fit me great and even had some extra room, it wasn't tight, which is perfect for wearing it over dress shirts or other sweaters, just what I wanted.Thank you very much, I'm looking forward to trying this vest out on the coldest days of Winter.Please keep in mind you must have your own battery pack with a USB plug to plug into this vest; they're usually $20-30 for a large capacity one if you don't own one already.

Bought this for my bf who is a trucker and works outdoors often.It is thin! Not bulky. You will need to buy your own portable battery pack for it to work.I've tried it too! and man... does it ever take the chill out!I can see this being used at the cottage on those nights where you want to sit by the fire but it's a wee too chilly. Be nice and toasty under a hoodie!Only downfall is that it would be nice to have a few more heated areas. But there are other more pricey versions with that option.But if you're naturally a warmer running person... this would be perfect.I always feel freezing. I am "that guy"Easy to use.

This is very slick. Thin but warm vest. I don't want to say I can't wait for the cold but I'll say that when it is, I'll be excited to try this. I put it on around the house and it was very comfortable and warm. I wish they would really advertise that NO BATTERY comes with tithe vest. I just started a new job where I will be outside all day so gear is key and I feel like this will be the centrepiece! Thank youAs far as sizing, Its a touch small but I took XL which is usually big on me and with this one its snug. A size bigger may be recommended but it may be too much.

I just got it and decided to try it out.. It was thinner than I expected. I took off my old Vest and put on this vest (and then put my old vest back on). It fits perfectly, I don't feel like I'm wearing two vests. I then plugged it into my usb power monitor and plugged that into my Dewalt 5AH Battery with USB adapter installed. It took less than a minute before I could feel the heat on my back. NICE...... As you can see in the picture, it Draws just over 1.5 Amp continuously on High until it comes up to temperature and then power cycles on/off. With it Plugged it into my Cell phone charger (12000 ma) battery, voltage drops to about 4.75V and 1.45A.Will let ya know later how it worked outside in the real world (after this cold snap)...
