Thermajohn Thermal Underwear for Kids, Boys Thermal Underwear Set | Kids Base Layers for Skiing | Long Johns for Boys Kids

I purchased 3 sets of long johns for my son. We kept these because they fit the best. They are really soft and my son loves them. Unfortunately after only a couple of wearings, the elbows on both arms are already wearing very thin, and a lot of pilling is developing. Additionally, some of the stitching is already coming loose. These were lightly worn around the house and not to play in. And at more than $25 after tax, they were not cheap for a set of kids long johns, and I certainly expected him to get more than a month out of them. Again, my son loves them and he does not care about how ratty they are already starting to look, but his dad does. Very disappointing purchase.

This is very soft and comfy according to my son and warm. I washed them as soon as I received them and they didn't shrink or create lint. I had originally ordered a medium, based on the product sizing but it was very small and I had to return it and order a bigger one. Delivery was very fast on both occasions. My son is 6, tall and muscular. He's 4'4" (52") and 69lb. He usually wears Youth Small to Medium in major brands. Medium was more like 5T. The XL fits perfectly but will be small next winter.

Bright colors and large selection helped on our mountain trip at Christmas, so I could get a different color for each of my kids.They never once complained about being cold with these on! In fact, my younger two didn't even want to take them off!This brand makes very cozy thermal underwear, the fleecing makes it feel like they're hugging you without feeling constricting or too hot.5/5 stars for quality, value, selection, and coziness. I bought sets for our whole family and would 100% but them again!

The size xs fit good for my 4years old, 55bls, 46 inches. He was comfortable, soft material and keep him warm in 9 deegree winter. Thumb up

I bought these in size XS for my average size almost-five year old boy, and the arms and legs are long on him as I expected they would be, but they fit so snugly it won't matter and he will just be able to wear them all the longer. I had him try them on right away to check the size, and he loved the feel of them so much he didn't want to take them off. I anticipate these will be a big help in keeping him cozy during outdoor activities here in upstate NY.

My son loves these! I got them for him to wear under his snow gear, but he wears them all the time as pjs. Very comfortable and soft on the inside, but still fitted like you want for long underwear. Will be buying again and again.

Bought it for my son that played soccer in cold weather. Worked great and kept his legs and upper body warm

My son wore these as a base layer for a 4 hour horseback riding event. It was 40 degrees outside with a slight breeze and he said they were comfortable to move around in and kept him warm, but not too hot. I have bought two more pairs!
