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.

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!

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.

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.

Fit ran large but kept child warm and dry in snow under snow suit. Durable when washed.

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.

Siempre he usado ropa térmica para mi hijo desde bebé, por lo tanto he probado varias marcas y éstas por mucho son la mejor marca que he probado, no hace pelusa, son muy calientitas sin ser gruesa o pesada por lo que son excelentes para viajar, realmente mantiene la temperatura y por lo suave y cómoda que es mi hijo está feliz de usarla, aparte de que no lo hacen sudar y esto para acampar en lugares fríos es perfecto 👌 ya compre dos veces más y ahora también compro para dama.
