Midweight fabric is warm. Cut is good.
Nice, warm fabric that holds up well. My kids use them under soccer jerseys when the weather is cold, as well as when skiing. Comfortable and warm. True to size. Lots of stretch. Have purchased several times as they have grown.

Very soft, high quality
Ordered two of these sets, one for each child. They are a nice weight, soft and thick but not bulky. they wore them skiing and stayed nice and warm. these are also easy to wash and dry. The fit is true to size but a bit on the small size so if your child is on the larger side of their size I would size up. The colors are also all very close to each other in shades of gray so it's hard to tell them apart even though we ordered different colors.

Warm, Comfortable, and Durable!
These thermal underwear are fantastic for skiing! They’re incredibly comfortable, durable, and kept me warm even in high cold winds. A must-have for cold-weather activities. Highly recommend!

Kept my son warm, soft fabric.
Wears well, kept him warm, pilled really bad after one wash.

Warm and cozy but pill
These are great they’re warm they fit perfectly but they do pill easily. Doesn’t bother me that much since they’re an under layer but it drives one of my kids crazy because they can feel it through the shirt. They’re very soft and hold up well in the washer without shrinking.

Very soft and high quality
Purchased the XL (US size 11-12) for my 10 year old. They are slightly loose on him, but would fit as they should for an 11/12 year old. I was impressed with the thickness, and quality feel. Very soft on the inside. The double layer of fabrics is perfect for our northern Maine winters. I would not necessarily use them for hiking or fall temps. Very impressed. Buy them.

Does the job!
This style of long underwear hold heat in well. My son wears them for baseball practice and games during the season. They hold up quite well, great quality. Love how soft they are inside, while the outside provides a smooth more athletic appearance.
