My little one didn't want to take them off!
I would give 10 stars if I could! I will be ordering more for my little guy. It was a struggle to get him to even let me wash them. He has issues with textures but these were perfect for him in every way. I ordered them for a trip to the mountains, thankfully they arrived 5 mins before we left (my fault for last min ordering). They are not thick and have a thin lining of fleece but they are smooth, soft and kept him very warm and comfortable on our hikes in the cold mountains. He wore them the entire trip barely letting me wash them. They wash well, no shrinking nor fading of the vibrant blue. This is definitely worth every penny. Thank you from me and my little one!

Perfect for below zero weather
I got two pairs of thermals for my middle schooler who is on the spectrum and is very picky with what they wear. They absolutely LOVED these thermals and didn’t want to take them off! They fit snug without being constricting and the flat seams do not irritate their skin. My kid is 5’ tall at age eleven and the size Large was perfect. They said they were warm and dry all day even when playing outside in the snow. I will be purchasing another set because the quality is fantastic. Honestly you can’t have enough for your kids especially if they are active.

Perfect fit and so warm
My son won't take them off. Got them to keep him warm under a Halloween costume. But he wants to wear them all the time now. So soft and warm. He is a skinny 8 year old. They fit perfectly.

Works great!
My son loves this set. It keeps him warm as pjs, under his clothes or under his soccer uniform. The quality is great. Worth the cost. Lightweight material but definitely keeps him warm. The blue color is perfect for his soccer uniform and just as pictured.

Ultra soft and warm
Boys winter thermal underwear fits comfortably under any clothes. The soft lining gives comfort and warmth in cold weather also keeps sweat away and prevents chafing.

Good but way small
It is warm however the sizing is too small. The top is way to small and although the pants are the right fit

Super warm and soft
My son loves these! I didn’t know if they would be warm, but he said he stayed warm the whole time and they were very comfortable. They feel like soft pajamas!
