Review: A must have - My son hasn't taking these off since the snow hit! He loves the comfort and warmth.
Review: 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
*by G***7 on January 15, 2024*

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.
