These fit well, are comfortable, help keep my son warm, wash easily, & are durable. We’ve been buying this brand for years. My son wears them under his pants on cold days & he’s also worn them for skiing.

Run a bit big, but otherwise perfect. Soft, warm, lightweight, and comfy.

I bought these for my 9yo son who normally wears a 10 Slim in pants. These fit just fine. There is plenty of length and enough room in the waste to allow for growth but no so much that they would fall of his hips. He thinks they are super soft and will probably use them for PJs more than as outdoor thermals. Hope this helps.

Good quality for the price, they fit my son as expected. I just wish they had a little window in the front for those toilets breaks. My son tells me that they are warm and comfortable. He's happy, I'm happy

I guess reading the fine print is very important. Looked in the men's section for thermal underwater. Saw these at a fair price, ordered them in my size, open the packaging, to my surprise they aren't men's they're children's. Made out of a very itchy polyester material not like thermals I've seen in the past. The medium didn't even fit my 10 year old brother. Amazon was nice enough to give me a full return of my money. Don't recommend if you actually need a good quality thermal insulator to keep body heat in and cold out. Polyester/nylon material doesn't feel very comfortable against skin in this density or grade.

The only problem here is the price but I can see why. They are, very, comfortable, warm etc. Plan to get more. After looking over this I realize that their wss one other problem. Looking at the mens version, I ended up this youth one.

Bought these for my daughter for a trip up north. Youth L fit her great (she is a Jr size 3-5 or small). They were cozy and warm. I am happy with my purchase of this item.
