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!

I originally bought these to take to Ireland with me, because Ireland is always cold and damp. Sadly, we never made it there. Now we are having the coldest winter in the Northeastern United States, and I (finally) took them out of the drawer. Please know that these are so warm and comfortable. The insides are nice and soft up against my skin, while the outside is smooth and slick. This lets you move around without any material binding or bunching. The material stretches with me and does not pull. It feels like a second skin. There are seams in the usual places, but they do not interfere with movement. I am 5'3" and 150 lbs. I ordered the extra-large and it fits me perfectly. I purchased the gray color, but it's nice to see they offer such a great selection of colors. I would definitely buy again. Thank you.

After the birth of my twins, my skin got very sensitive to different kinds of fabrics so I'm always weary of trying tighter clothes. I am 5'4", 115 lbs and bought the small. It fit slightly loose, but well. These thermal base layer shirt/ pant combo exceeded my expectations in every way. They are so soft... I don't ever want to take them off. I have a long torso, and the shirt went down past my waist. I wore them skiing with temperatures in the single digits- I layered them with yoga pants and a running shirt... plus snow pants and a jacket. I'm always cold and for the first time ever, I felt warm and comfortable on the slopes for 6 straight hours for 3 days in a row. So so happy with this purchase and with these base layers. Yea!

True to size (since I'm 5'3" I can usually squeeze into a medium by sheer will, but prefer to buy a large for a proper fit and this large fit me perfectly; for reference I'm a size 8-10/fluctuating). The top was longer than I expected based on the other reviews stating it was short. Mine tucks into the pants and then some, possibly because I ordered my actual size myself, rather than the size I can squeeze into. ;-) If you have extra weight on top, or have a larger bust, definitely consider going up a size. Super soft and extremely comfy, and they fit perfectly under my tight jeans. The trim detail at the neck and the fabric look cute peaking out from under my tops. Pretty warm in 40-ish degrees; and in 20-30 degrees with snow flurries, I felt warmer than not wearing them obviously, but was definitely feeling the chill and wind. Overall, I'm not sure how these keep the Minnesota ladies toasty warm, but they will do for milder winters like 20-50 (hey, 50 degrees is nuclear winter if you're nearer to the equator). I am from warmer climates myself and this is the coldest winter I've experienced in more than 25 years (just moved to Oregon), so I also feel colder than your average snow-treading Oregonian for sure. I personally think they feel great on the skin (so silky), but they aren't flattering enough to wear alone around other humans unless you have a pretty sweet, rockin' bod. Look away, look away! Overall, 4 stars and I would buy them in more colors.

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.

I LOVE how VERY SOFT the inside of this fabric feels against my skin. The fabric is also much thicker and sturdier than a pair of expensive, allegedly silk, pair of long Johns I tried. The fabric on the other very thin, allegedly silk brand I tried looked like I had dragged it across rocks after wearing it once. The fabric on this pair still looks brand new after wearing it several times. This fabric also keeps me nice and warm without being too hot. I bought a medium. I’m 5’4”, weigh ~126 pounds, and have a slight belly bulge. The shirt and the pants fit snugly, but are not too tight. The shirt is a bit longer than I expected. It comes to the tops of my thighs. The sleeves are the perfect length. I like these so much, I’m planning to buy another pair.

Update: have worn this twice in total and there’s a small hole in the crotch. Quality control is lacking, knocking down another star simply because of it. Does the job of keeping me warm, but come on. Paying almost $35 for a set of undergarments and already having issues with stitching is ridiculous. ***Note that this arrived last night 12/28 and I put them on this morning 12/29 and there’s already hole in the top as mentioned with the picture… Don’t really like that for the price, as it has me questioning how long these will last. First impressions seemed great though. Would’ve given it 5 stars otherwise. Can be worn under clothes without show, they’re perfect for winter or even just having it place of pajamas or wearing warmer clothes.. you feel naked (big plus from me, I don’t like how clothes feel) with a layer of warmness on your skin and it feels sponge-like. Press down on the soft side of a sponge or even better: a Mr clean magic eraser (more accurate feeling) and imagine a thin layer of that on the inside of the clothing covering your whole body, that’s what I mean. Plus the warmth. Good stuff. I’m a thicker woman, short, ordered a Large and it fits like a glove. Will definitely be ordering more.
