Super warm and cozy
Love these long johns! They are so warm and cozy. I love that they’re thin enough to be worn under most of my clothes but they still keep me warm. They fit well and snug, but not too tight. Good quality fabric that is silky on the outside and almost like a down material on the inside. Really good value, considering how often I wear them.

This thermal wear set is fantastic. The quality is excellent, it feels soft and durable, and it’s very warm—perfect for cold days. It fits the body very well, allowing comfortable movement while keeping warmth. I’m very happy with this purchase and definitely recommend it for staying warm and comfortable.

Favorite base-layer thermals
Love these base-layer thermals, navy was my third pair. I wear these under ski pants skiing when temps are below 32 and also as just a base-layer under thinner pants around the house when weather starts getting cool. I would call them a mid-weight not too thick but not thin either. Feels so soft, comfy, and stretchy but doesn't stretch out after wearing. Good quality, they have held up well washing and drying on low. Took 3 years for my first pair to even start showing signs of thread in waist seams coming loose. Hope the black color comes back in stock soon.

Runs a little small
They ok. It runs a little bit small normally wear a medium but got a large and it was still a little bit snug. Next time I will get a XL. But it’s warm and cozy.

Looking for Long John's? These are EXACTLY what you want!
I am relatively a hot (temperature wise) person. I absolutely hate long sleeve shirts and I'll walk around with a tank top under a cardigan all winter. I've NEVER owned a pair of long John's in my entire 44 years of life. But last week I started experiencing cold biting through the arms of my cardigan INSTEAD of having to remove it because I'm sweating. I started getting so cold I couldn't get warm enough to fall asleep. After layering some pajama bottoms under my VS leggings and feeling that they were so tight like I was going to puke every time I sat down, I decided to get an Amazon and find myself my first pair of long underwear. My hopes and expectations were low. I searched and read, searched and read and searched some more. Everything I've ordered lately, I've had to send back and replace with a smaller size. I am super picky about my regular clothing and feel like every pair of jeans or leggings never fit in between my legs right. I'm constantly pulling up at my waistline so I don't look like a toddler with a full diaper. But I HATE that feeling when your clothes restrict your movement, or move down EVERY time you do ANYTHING. I didn't know what to expect, and after putting multiple items in my cart and taking them out I ended up with this set in a smaller size than Amazon recommended in the color navy. Did I prefer a lighter color to wear under lighter clothes? Sure, but navy was the only option that could be at my door, literally later that day. I was done with being cold. I was prepared to be disappointed.... not to mention I would STILL be cold so my hopes were down. I don't know who designed these for women, but I am your number 1 super fan. I've never put something more comfortable on my body in my entire life! They are form fitting without being even the slightest bit tight. The bottoms feel like a regular pair of leggings... except somehow LIGHTER and there was little to no extra fabric, yet somehow just enough to cover all the space in between the top of my socks to right at my belly button. The fabric, which seems to be the same in and out is SO SOFT it feels like my whole body is being hugged by the lightest and fluffiest cloud. The top, let me tell you, I think my biggest hatred of today's clothing is that EVERYTHING seems to be working it's way more towards a crop top. I was pleased to put the top on and have the bottom sit way well below my underwear. I can't express how happy I am to have gotten these on my first try. I literally haven't taken them off since I got them yesterday. Not only have they held there stretch... I am staying at a very nice and warm temperature. Definitely NOT cold... but even if I get a little hot this fabric doesn't hold the hot in. This is EXACTLY what I needed and was looking for. I would recommend these to any woman and they will be the only brand and kind of long John's ill recommend... like ever. Now I'm just not looking forward to having to wash them. I guarantee I'll be putting them right back on!

Extremely Warm and Comfortable
These thermals and extremely warm, soft and comfortable. I bought them for a trip to Xmas markets in Austria and they kept me warm with a light thermal pants on top. I also wore them to a Greenbay packers game in the snow and they were perfect. Highly recommend and well worth the money. I normally were a medium and ordered a large and I am glad I did I didn't want them to be tight. I usually wear a 8-10 size.

Great Product Only When you Buy the Black Set
The Thermajane Long Johns Thermal Underwear for Women is an excellent product if you buy the BLACK set. The navy color has a problem in sizing. I ordered the black color a year ago and it is of excellent quality and the fit is perfect: XS / 5'2" and weigh 115 lbs. But I ordered a NAVY set and discovered that the waist band is very big in comparison to the black set I purchased. I sent photos to the manufacturer / 3rd party seller and they simply concluded that I ordered an XS in Navy and did not take the time to analyze the photos that demonstrated my point: the waistband is too big and does not fit the XS sizing. Fortunately, Amazon is an exceptional Customer Service provider. They directed me to return the product under their supervision and now I can get my A-Z guarantee and a monetary reimbursement. Even though I absolutely love the black set of thermals that I purchased a year ago, I will never purchase from this company. Just finished purchased a set from another company. Too bad that some 3rd party sellers ignore customer concerns. Starting to order directly from Amazon exclusively.
