Awesome
Bought these for my son and man he said he was realy warm even on an extremely cold day. Fit was tiny but big even in the smallest size but fine cause he can use for multiple years. Incredibly soft and feels great to wear!

length is great and very soft!
Excellent mid-weight merino base layer for kids. Stretchy and the arms and legs are long! My kiddo has trouble with the arms and legs of base layers being too short, but these are excellent and very soft!

Great quality, had to size up though
The price for this set was so much better than any other wool set and it’s wonderful! It’s very comfortable and warm. I bought the smallest size for my 3year old and it’s a little long but still fits him just fine. Wool is usually tight anyways but I had to go up a size for my 6 year old, the size recommended was way too tight on him.

They fit well and are made of good quality
They are quite comfortable and doesn’t itch. The quality of the fabric is better than expected since it wasn’t itchy so it’s a must have for staying warm. They fit a bit bigger but it’s fine since the lil ones will grow into them.

Soft and warm
I realize that some people pass these up because of the price. I also realize I could buy regular cotton thermals for a lot less money but nothing beats a good pair of thermals. When I take my kid hunting and ice fishing I want him to stay as warm as possible without sweating. Nothing is worse then hiking to a hunting spot and sitting down and getting cold because my kid or myself broke a sweat on the hike out because we had to many base layers on or base layers that were all wrong. I learned very fast that merino wool socks keep my feet dry and warm and the merino thermal underlayment was just as good and if I didn't cheap out and buy a mixed material I would find these things just as good for my son. He is 8 years old and these things are the best! We have went ice fishing and he never complained about being cold. We sat on an all day deer hunt and he didn't complain once about being cold. The material is lightweight but keeps him warm and dry. They fit him perfectly. I am very happy with the purchase!

Not merino wool! Cheap polyester.
This was not wool. Pretty disappointed once it was received as the description stated 100% super-fine merino wool.

Excellent product and quality. Soft, warm and comfortable. My child is 6 years old and fits slightly big but he is tiny. I’m glad with this purchase.

I wasn't to sure, because I usually buy other brands at a much higher price point. But these are great. Very nice soft feel, my kid has been using them to run around in winter underneath his regular clothing. He does not complain as they are very soft. Soon we will try them during winter sports. For a 250g it is exactly what we wanted. The included beanie is a nice touch
