Very pleased with this purchase. Super soft lining and long lasting batteries. The battery pack is quite big and I would say that is my only complaint. The battery that goes in the side pocket of the pants tends to be a bit cumbersome but it's worth it to keep warm. I got a size small. I'm 5'6" and 127lbs. Tight but comfy fit. Just how I would want thermals to fit for snowboarding. This is going to replace multiple that I usually wear to stay warm on the slopes. It comes with a cute little case to store then in which comes in handy! Highly recommend! Read more

These thermals are AMAZING! Love the heated base layer set. The base layer heats up quickly, and stays warm. You will not regret purchasing these. Toasty warm and extremely comfortable. Read more

Didn’t work at all. I bought them for my daughter she works nights outside at Penn State. It’s freezing and this product failed to deliver. Read more

I consider myself someone who feels the cold down to my bones, so when I saw this heated long john set, I was equal parts intrigued and skeptical. I imagined a bulky, awkward suit with wires you could feel from a mile away. What showed up, however, was a surprisingly soft and normal-feeling base layer. You'd hardly know it was a piece of tech until you plugged it in. The magic happens when you connect the included power bank. A gentle, consistent warmth spreads from the panels on the torso and lower back. It’s not a scorching heat, but a delightful, "I-just-sipped-hot-cocoa" glow that makes standing in a freezing ski lift line a much more pleasant experience. The fabric is stretchy and moves with you, and the USB port is discreetly placed. My big hope is that this cozy circuitry holds up to many winters of use and repeated washing. Here’s my personal take after testing it out: What won me over: · The heat is wonderfully even and feels genuinely therapeutic on a cold core. · The base layer itself is comfy and warm even without the power on, which is a great bonus. · Having a separate, hot-swappable power bank means you can use a portable charger you already own for longer adventures. What gave me pause: · There is a very slight bump where the wiring is, but it's not uncomfortable against the skin. · Remembering to charge yet another device (the power bank) is a small but real step in my routine. If you dread the deep chill of winter sports or outdoor work, this set is a fantastic solution. It’s like having a personal, wearable heating pad that lets you stay active and warm at the same time.

I got this set of heated thermal underwear for my girlfriend who is always cold during these long Wisconsin winters. I told her that I got her some "hot underwear." She seemed more happy that they were heated underwear than if they were the sexy kind of "hot underwear." After unpacking these garments I connected the batteries and turned them on. I could feel the heat as they quickly warmed up. I was a bit jealous of her as these things were too small for me to wear. She tells me that the heat from the top and bottom sections is pleasing and keeps her plenty warm as she goes out for her cold nightly walks around the neighborhood. She also likes being able to plug and charge devices with the battery packs. She was a bit nervous the first time washing them, but after 3 or 4 washes, they'll still work without a problem. Note: 5-Star ratings from me represents that a product meets and/or exceeds my personal expectations for and not limited to functionality, build quality and price. Read more

These are amazing!! They do run small, I recommend 1-2 sizes up depending on how you like it to fit. I’m 140 5’7 normally wear a size s/m and ordered a large in these, they fit snugly. They are lined with a velvet texture and the top is kind of compressive almost, the bottoms are more like a pair of joggers than long johns, so may have a hard time layering the bottoms if you like a tighter fit as these are bulky. They come with 2 battery packs and they hold a good charge, several hours. The buttons are easily accessible (top of pant and bottom of shirt) they do get quite warm especially layered under other clothing. These comes with a super nice case to store everything in as well! They are washable but recommended to wash sparingly in instructions. I have a lot of sensory issues when it comes to the clothing that’s making contact with my skin and these don’t bug me at all, I can somewhat feel the wires running through but the thick velvety lining helps with that a lot! These are such a good price for the quality, and all that is included. Plz excuse the dog hair it’s just a part of my personality at this point when wearing anything dark lol. Read more

This usb,electric, thermal heated long John set is incredible! It even comes in a sturdy zippered carrying/storage case. The thermal 2 piece long John set is excellent quality. The fabric is really soft. It has two usb battery packs for charging. It really gets warm and it feels wonderful. The top and pants fit great. True to size. The set comes with instructions on how to charge with the battery packs. This set feels lightweight and fits well underneath clothing, and it works great to keep me warm even in Wyoming snow. I love this thermal underwear set. I definitely recommend it. I rate it a 5 out of 5... Read more
