Thermal Underwear for Boys Long Underwear Set Ultra Soft Base Layer Kids Warm Pajamas Long John Set 2 PCS Black 7-8Y

This is precisely what I was looking for - fleece lined warm thermal underwear while being very thin and flexible. I was looking for something that'd be warmer than basic thermal underlayer for kids to wear to ski trips and was expected that I'd have to go with heavy fleece pants and shirt, which would be uncomfortable and hot. This set has a very thin fleece layer on the inside, which I'm sure would provide sufficient warmth, while still feeling like an underlayer rather than outwear.Fits great and feels sturdy. Time will tell how it lasts.

It’s warm and perfect!

Very well pleased with these! They fit him as expected. These are extremely soft and cozy. These make a perfect base layer. He doesn't complain when he is asked to wear them under pants or shirts,he is completely in love with the softness and texture of these and doesn’t ever want to take them off. They maintained their shape and size after I washed them as well.
