Really Good

bethD—November 14, 2025

Fit great. Nice color. Nice and thin to wear under pants but still warm. I've reordered these in 2 other colors as they are comfortable, easy to wash and wear, soft, fit great and are a good deal. Read more

Just Buy Them!

Schelly L. Wagoner—November 18, 2025

Y'all, I'm not even joking you - these are amazing. I have some long undies in cute patterns that I sometimes wear as leggings during the winter months, but I got these strictly to go underneath clothing while I take care of my chickens and do outside stuff. The features I was looking for in a pair of long johns were these: I wanted them "second skin" close so my pants or dresses wouldn't appear more bulky than my body makes them. (sigh) But I am not comfortable in compression gear, so while they should be close-fitting, they shouldn't be restrictive. Also, I wanted the external shell to be very smooth so whatever I was wearing would slide right over them. Lastly, of course, is warmth. I really need them to be warm, because folks - we're in for some very cold weather soon. The Thermajanes are exactly what I was hoping for. They fulfill every requirement and they're SOOOO comfie. I'm a size XL and these are true to size. I cannot recommend them highly enough. Read more

It WORKS!

Mischele M. Wilson—December 18, 2025

This SAVED me during a recent trip to the Christmas Markets in Germany and Austria! Thin enough to wear under jeans and other pants, and it made a real difference in keeping me warm and cozy. Read more

soft, warm,but a little short

Mamamia—November 3, 2024

I bought two pair of these long underwear to wear under my clothes in the cold weather. They fit snuggly to your body so they don't cause wrinkles under your clothing, they're soft, yet thin, and keep me warm. Unfortunately like most long underwear they could be about 2 to 4 in longer so they cover your ankles. Not sure why the manufacturers of long underwear think that we want them to stop above our ankles, and I'm only 5'3" and they stop at least 4 inches above my ankles, which allows cold air in. They wash up nicely, a machine washed normal, and dried on low heat. Also, the rise is high, allowing it to cover over your stomach and keep you fully covered and warm. for size reference I'm 5'3 and weight about 135 and the size small fit perfectly. The elastic in the waist is about 1 in high and is pretty stretchy. Read more

Soft, comfortable and WARM!

Connie McGuire—January 19, 2025

These thermal underwear are so soft and so comfortable and they are a perfect fit. I like how when I kind of push the sleeves up a little they’re not binding on my arms. They have just enough give to stretch without getting stretched out and they definitely do not cut in on my forearms. They’re nice and warm and I love them!!! Read more

Warm, but fit is odd

Chowder Head—February 5, 2025

Based on other reviews I ordered a 2X, which is larger than my regular size, which would be large or XL for something form fitting. Was glad I did because it fits more like a large. The first time I put them on I thought I had them on backwards because the fit felt so odd. Have not had that issue with similar garments. Also, I'm short, 5 feet, and can't see how this would fit someone who was tall, say over 5 feet 5 inches. They are warm and the inside feels soft. I kept them and have been wearing them, but will probably not buy this brand again due to fit. Read more
