One of my sons requested these as a gift. He is built slim and most pajamas swim on him. I read the reviews that these ran a bit small so I ordered him a medium. They fit perfect.

He wears it to bed and says it is very soft and comfortable.

Just what I'd hope for. Great fit. I ordered a size larger so I could get the length needed for shirt to stay tucked in. Very happy I did that.

This fabric cannot feel any softer on my skin. You just want to sleep in it all day and night long. Mix and match your colors!

These are the most comfortable underwear I’ve ever worn. A couple of times I have actually had to feel for the band because it felt like I was wearing nothing.

I bought these planning to buy other more expensive ones to compare with since I live in Vermont and wear thermals from November to May some years. I like these so much especially for the price I decided to just order more of them. For sizing reference I'm 6' 190lbs and a pretty normal athletic build and the L fit me better than any other thermals I've worn in 15 years of New England winters.

This is a really warm thermal underwear set that fits snugly but stretches. It is very soft inside and feels like flannel. The outside is a breathable material like polyester that does well for sports or camping/hiking.

These are very lightweight and at first I doubted they would keep me warm. Once I wore them outside the first I was amazed at how well they kept me warm. They do run a bit small but not much, and they have a good stretch to them. Well worth the price.

I love these Thermals. They fit as expected, and you can throw a regular large t-shirt over them for multi-seasonal usage. Layering is key!

My husband is from Costa Rica and this is his first winder in the cold north. He started feeling chilly, so we looked at Walmart for long johns, but they were not soft and they were about $15 for either pants or the shirt. This is the second set I have ordered in a week because he wears them every day. They are super warm and soft on the inside and thin enough to fit under your shirt comfortably. The fit is great, he is a big and tall guy 6'6''+ and 290 lbs so they are perfect. Some people say they are not the best quality stitching, but really

These are the nicest thermal pants bottoms that I have ever purchased. They are very warm and comfortable and they are sized perfectly. The thermal pants elastic waist band material is very wide, which means they stay up well and they are very comfortable to the waist. If I had not bought as many as I did I would have re-ordered this product without a doubt. I will never wear my older narrow elastic long john bottoms ever again, they are going in the rag bag.

I’ve tried several brands of thermal underwear. These are my favorite, by far. They’re warm but not too warm or itchy. I wear them almost every day during the winter.

They were what I expected. Fit was great. I'm a police officer who works late into the night and early mornings, so I'm in the cold. I wore these the first two nights and didn't even need my jacket and my legs were extremely warm. I love them.

I bought this thermal fleece top for my husband. He really likes it because it is warm without being bulky.

SO WARM, these are great, I love them, wore them to a football game in the middle of winter and my legs stayed good and warm, even sitting on metal seats in 20 degree weather. Very high quality will last multiple winters

These are not like thermals you are probably used to or picturing in your head. These are thin and feel like smooth felt. I don't own any clothing that feels like these do, very unique in that regard. It's still late summer here so I can't attest to how warm they are but one thing is for sure, they don't feel scratchy or uncomfortable. They are more like wearing silk. You may not even notice you're wearing them.

So far so good. I workout, so my legs/hips are a little bigger than average. Yet, the medium fit fine. If I got the large, I assume those would fit fine as well. I wear these under my jeans or pants on cold days and they do a good job of keeping me warm.

I love these. I take them camping and I stay extra warm. Fits great and don't get all twisted up at night.

Fits as expected. Husband is 6'1" 198 got a large son is 5'6" 135 got a medium. Stitching around waist was off but I can fix it. Live in Florida, got these for a trip to Alaska. When you buy boys black outfits they want to put them on and be ninjas.

My first purchase was two years ago in preparation for my 2 week trip to Iceland. Packs conveniently while saving space and weight. Caring for the fabric is simple, hand wash it if you wish, or use a machine. Hang it for a quick air dry. It also manages to hold its shape. With the cold season at hand, I feel prepared with the two shirts I just purchased.
