Great fit, quality + warm and nice stretch.

I wanted to write a review because I am really impressed with this set! For reference, my son is about 52.5” tall and 82 lbs. I purchased two sets for my sons to wear under their jeans horseback riding and for playing in the snow. Unlike just about every other pair of long underwear we’ve owned, this set has washed well without much, if any, shrinkage and keeps them warm. They haven’t mentioned feeling cold horseback riding since we started using these while layering clothes. Typically they wear this under jeans and a sweatshirt followed by a coat and they have been riding in temps in the 20’s. The outfit is warm and very comfortable. It doesn’t have the rough feel typical long underwear has and the fabric has a good amount of stretch. I would recommend these and I would also get a backup set because they like them so much. Can’t beat the price too. I’ve been warm water washing and putting them in the dryer and the fabric hasn’t changed feel or faded. It’s holding shape well too. Read more

This set fits toddler good! It's hard to find a perfect fit! I love the thickness of the men's thermals, soft and comfortable. Great price! I received it fast and well packaged. Thanks Read more

It’s a bit big on my child. He is 11 and a half. I ordered XL he is on the very slim side though. He is about 57 inches in height and around 70lbs. He does have some room to grow but can still wear. The top fits pretty well a big baggy on him and the sleeves are only slightly to long.the bottoms are a bit loose in the waist area but stay on . He is a kid that usually needs slim fitting pants . They also seem to have a good amount of stretch in the waist as well. Have not washed yet as it’s so cold today he immediately kept it on after trying. It could shrink a little will update if it does. He says it’s very warm. He also wants to wear the top as a shirt . I expect unless he does major growth spurt he will be able to wear for a few years. Amazon kept trying to get me to order the xxl. I would go by the listed measurements in the size chart. Read more
