ROCKY Thermal Underwear Kids, Boys Thermal Underwear Set Long Johns Thermals Kids Base Layer Kid Thermals Top Bottom Set Boys, Black, X-Small

Soft and sensitive friendly. These keep the kiddos warm and are comfortable under snow gear. True to size.

These are the best as far as quality, comfort, fit/sizing! I have bought 6 other brands of base layer sets from target, REI, etc and had to return them all because of poor fit or tiny sizing.I ordered 2 sets each of this brand for my 2 boys (8 yo, size XL, and 3 yo, size XS) and will be ordering more of these to wear under clothes for winter and as PJs.The material is silky smooth on the outer side with a thin, extremely soft fleece fabric on the inner side. Very stretchy, which is perfect for my 8 year old, who is more the size of a 13 year old. My younger son LOVES the car and firetruck prints!

Worked really well for a Florida boy who loves skiing. Kept him warm so that he can enjoy the harsh Colorado winter skiing trip

I bought these for my boys to wear as a base layer for soccer. At their age, I just couldn’t justify name brand base layer, when they grow so rapidly. They were exactly what I needed, though not quite as thick and warm as UA. For the cost, they’re perfect, and now they can wear them through the winter. They did not fit snugly, as I hoped, and in fact, they were baggy. I bought the sizes they normally wear. If you want snug fit (for kids, anyway), buy a size down. Not a big deal, as my kids will grow into them, and if they hold up, they’ll wear them for the opening of spring season.

Material is warm, no pilling, wash and color remains no fading. Good value for money. True to size. Would buy more. The material is not too thick.

buying for the second time. It's an ideal skiing inner layer option for kids: reasonable price with amazing quality

The inside of these were so soft my boy didn’t want to take them off. Kept him warm all day in very cold weather with no complaints.

These are nice but they run very big. Won’t buy again.
