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.

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.

Functionally these are great. Keep kids warm and are comfy. Quality not great they pilled after 1 wash and have continued to do so with every wash since. Not bad for the price but are already looking pretty shabby

These are really nice and I have ordered a few, but the sizing is very inconsistent. These are both tagged as XXS and one is many inches longer, as well as larger in the waist and legs. We do like them, so we'll keep some that seem to fit. Unfortunately we have to just try them on to see which ones work and which ones don't

I ordered these for my son who plays hockey. They are perfect for under his equipment, allow for movement, great level of warmth, and have held up really well with lots of practice and game use. We have also used them during sledding/skiing!

Ordered the size Large for my son who is 10yrs old based on other reviews who said the Medium was a bit snug for their 10 yr old. They are so fuzzy, nice material, color was as pictured & while just a touch big on the waste for my son he can grow into them. Great purchase for the price! Will be buying for my other children.

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!

We buy these every year for the kids under sports uniforms etc, this year they seem a little bit bigger than usual but absolutely love how soft and cozy they are.
