    So far so good
  

*by M***T on Reviewed in the United States on October 24, 2021*

I've only used these 3 times so far. But they heat up quick and I feel the heat penetrating through my body. I've only used them in slightly cold weather so far (I always want to be super warm) but they get hot quick and I had to turn it off some of the time. Which is a good thing! I think the batteries might last 4 hours on full strength. I didn't time it though. I may buy some spare batteries...

    They take the chill off
  

*by R***Y on Reviewed in the United States on January 11, 2022*

They work well. I’ve had them for a year or so now and I am glad I have them working on a roof. I had to buy extra batteries as they die quickly but that is expected when used a lot. Downside is I wish they covered more area of your body. The top only has it on one side as do the bottoms. It would be nice if it was the whole  Garment and not just sections but paired with other layers it does the trick on cold days. Next purchase the socks. Overall I’m satisfied.

    size up
  

*by F***  on Reviewed in the United States on November 30, 2022*

So the sizes run small . I went up a size when I  ordered. Realistically if I had known I would have ordered 2 sizes larger than my normal .As far as function , They will warm you up for sure and the battery life is decent . My gripe is the placement of the power button on the long underwear , it is at the waistline and was turning on and or going through the power settings when I  was sitting  ( I used these for hunting ) . It was a minor inconvenience . Overall , for the price and time of delivery this product is great .
