Battery placement isn’t great. The top and bottoms put the battery on the same side of the garment which can be bulky

Love both pieces. Battery does not last very long--on low only 2-3 hrs

I bought the vest four years ago and got the pant and shirt this year from my wife for Christmas. After seeing how the vest worked and fit, she felt the resultant loss of "bulk" would be a healthy thing for a 68 yr. old guys heart and thought it to be a "great investment". So instead of talking about one item I'll tell you about all three. They all perform as advertised. Most times even with temps in the low 20's I only use the "LOW" setting. Perhaps towards the last hour I'll jump them up to "MEDIUM" (three hour local "morning / evening hunts"). Uniform coverage with elements as shown on web site provide effective coverage. In the mid to low 30's I use the vest only over a light type of base layer. Once into the mid 20's I have discovered the comfort of the pants and shirt. Low 20's on down I wear the merino wool base layer from Pnuma as well. (I have never worn a more comfortable pair of "long johns" in over 50 yrs.!) The combination works great. I'm still experimenting with internal layers matching up to which external layers. You see in addition to the fit, the construction and overall excellent quality the heated core has given me something else that I lost some time ago. Due to their performance AND their LIGHT WEIGHT, I no longer look like the kid brother in Christmas Story. I have had 9 vertebrae fused. Last surgery was last year and this year for the first time in five or six years I can walk without pain and negotiate uneven terrain in the woods. I also have COPD and it is sometimes very difficult to deal with in the woods with the bulky outfits I had to wear to keep warm. It's like I've lost 30 lbs. I wear next to nothing with the Heated Core Line compared to without it. Episodes of shortness of breath are fewer and don't last as long. I truly can't describe how that result from using the Heated Core Line has changed my life by giving me back the ability to enjoy something I love so much in the manner I was accustomed to before my stupid choice to smoke caught up with me years after I had finally quit. My hat is off and I extend my hand to the folks at PNUMA. I am grateful for all you've put into your product lines and customer service.

Quality baselayer without using the heat. I have worn these about ten times in various temperatures. I have only used the low and medium setting. I bought medium . I am 5'10 and I have a 33 inch waist. So far the battery has lasted as advertised. I bought the vest and an extra battery. Should have bought heated baselayers long ago.

I hunt Michigan and hate sitting in a box blind or running heater. I do everything I can to sit in a tree stand. I usually sit all day and was looking for a product that would allow me to bulk down on the layers. The product fit as I expected. 5"11 200 LBS. XL pants L Vest. The heat takes off the edge and makes a more comfortable sit. I wait until mid-day to turn it on. I start low and increase the power as needed. I purchased an extra battery. The battery placement is a design flaw. The vest battery and pant battery end up almost being on top of each other. I wish the battery packs were larger and on separate sides. I found the vest was a little uncomfortable. I wear a thin T shirt under it. Overall I am happy with the purchase.

Great gear only issue is sizing. Too long in the legs and no shorter options.
