I love this heated thermal set! It keeps me warm even in very cold temperatures. The fabric feels high quality, not itchy at all, and the heat settings are easy to control. Perfect for walking, working outside, or travel in winter. I would absolutely recommend this to anyone who gets cold easily.

Bulky under clothes but will keep you warm . Make sure you get battery packs for both pants and shirt.

some say it’s stretchy and others say it’s not. it’s really somewhere in between. the fabric stretches a bit but if it’s tight on you, you’re going to be uncomfortable – especially with heating elements against your body. my product arrived with pants that don’t work. i tried multiple different batteries. when pressing and holding the button, the light blinks 1 time quicky and nothing else happens.
the shirt also sucks. the image shows a whole bunch of heating zones all over. i bought this product over others because of the heating element coverage. only about what looks like half on the back and someone the belly get warm. not sure if i’m doing something wrong maybe. the product came with no instructions.
the fit is nice though. i’m 5’2″ 120 and it’s pretty much perfect. based on what others say and that i got a defective pieces i’m scared to wash it when i get a replacement. gonna return this one and see if the next one works.

update:
this has been the worst experience with a seller i’ve ever had. after getting pants that don’t work i chatted with amazon and arranged to return the item. after putting it in the mail i got a message from the seller that they would send me a new item free of charge and i didn’t have to return the item – oops. i told them i had sent it back and purchased another. i wanted to give them a second chance. they claimed the reason the pants didn’t work was a result of poor shipping or an accident in the process.
when the new on arrived it arrived without a shirt. at least the pants work. kind of. the image shows heating all over but it’s mostly just in the thighs and a little in the butt. i messaged the seller again to ask for them to send me the shirt i paid for. he asked i needed instructions – obviously not reading my message. he asked for my address and what i size. i sent the information and waited.
and waited. and waited. in the end the shipper sent the item back to them because they had entered only the city, state, and zip code. no street address. i messaged the seller again and they tried to blame me for giving them a wrong address. i sent they a screen shot of the amazon message i had sent them previously told them to compare that with what they entered. they then resent the item and gave me a tracking number.
i finally got it but it was the wrong size. it was 1 size too big and isn’t going to fit under my clothes making it mostly useless. at least it works. by that i mean that only some parts heat up and does not at all cover your whole body in heat like the picture suggests.

My husband loves them, remember they come without charger. He loves the quality. Took them ice fishing he was sooo happy.

These took forever to get but they are well worth the wait I posted a bad review based on how long it Took to get because the order kept saying delayed every day, but these thermals are well worth the money. They are very thick. You don’t even really have to turn the heat on in them, but I rode to work and it was 20° on a bike and I was cozy. I had to turn them off because I was so hot!!!

I bought this Heated Thermal Underwear for my boyfriend before the big freeze. He works outside in an airport in Chicago weather hitting minus 20 degree wind chills. And he said he was comfortable and warm with this under his uniform. Great purchase. Highly recommend! Buy extra batteries

Not heating at all is till good to have it on but for some reason the heatin Temp is not coming up I use a 20000mha but still not working
Ricardo Thomas –
Really getting great use out of this heated outfit. I use it in conjunction with a small Vornado space heater to work or enjoy my neighbood views out of my building’s terrace . very Comfortable and works as intended. very happy with it. I so many heat elements I haven’t had the need to use the maximum setting yet. One very small drawback: because I am sited most of the time it can get a bit hot in the lower stomach area. it uses little battery power also. I use 20000mAh Power Banks, after 4-5 hours I still have at least 50% or more battery power left. I would highly recommend power banks with digital readout so you know exactly how much power you have left.

Great buy!

Total game changer for those who freeze in a hunting stand or on motorcycle. I am that person who needs a million layers or 50 different heated products to stay warm. Out of the box these are the best! True to size, fabric is comfortable and did I say this already…..warm! Only downside is having to order the batteries separately. Nonetheless these are the best purchase I’ve made in a long time.

You have to supply your own batteries (2) for this item so overall this can get pricey. The thermals seem to heat up nicely. These are not thin like normal thermal underwear. Both the tops and bottoms are thick as they need to have the heating wires in them. Sort of like a thick sweatshirt. So the issue is, what do you wear over them for the bottoms? A normal pair of pants won’t fit over them unless you have an extra large pair or have ski pants or something like that. The waist on the bottoms is a stretch band. I’d prefer a drawstring too since the stretch could lose its stretchiness over time. Quality is good. So at least in their brand new state I have no issues, other than the thickness.

Great product, comfortable and lightweight. Definitely will keep your body warm.
Great customer service and really affordable price!
Thomas Bernero –
It does require 2 batteries one for the pants and one for the shirt. It is very high quality thick material, which unfortunately makes it kind of uncomfortable as underwear and more like regular clothes. You could definitely wear this outside by itself and be warm. With the battery of course.
Garrett Ryan King –
Worked pretty well first the few times I’ve used it. Does not come with batteries. Will update if it starts having issues.
Karl Salohcin –
It really does not come with the battery. And get this. You need two batteries to power this, one for the upper part and one for the pants. But. Upside… you’re gonna buy two 20000mah batteries and plug them in. The shirt gets warm in about 6mins after turning them on and the pants take about the same.
The “sleek” appearance & fit is pretty good. I’ve worn to & from the kitchen but I might chance a walk with my dogs to see if it meets winter weather adaptability quality wise. As this purchase is strictly for use during winter months.
Amazon Customer –
Thick but I liked that. Everything heated up except the chest area
Chris –
So warm and nice quality. Very thick and work well. Great price.
Tara Coriell –
My husband wore his set all winter while working outside as a construction worker and didn’t even need to use the battery because they keep body heat in so well!
Kindle Customer –
Works ok. Not good in extreme temps in less than 32.
Shawn Madison –
Bottom heats very well. The top could use more heating pads..
mary e scell –
Did not come with the batteries pack.
Amazon Customer –
EXCELLENY BUY !!!!!!
John –
No batteries included. The sleeves on the shirt barley get warm. Hard to tell it’s on. Not worth the money. I have been burnt every time I’ve bought heated gear off line. This company under delivers. Save your money.
