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! Review: 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. ## Features - ULTRA SOFT & WARM FABRIC: Kids Thermal Underwear is made of premium silky soft lining for excellent comfort and warmth in cold weather - MOISTURE WICKING & BREATHABILITY: Breathable and moisture wicking fabric is perfect to keep sweat away and dry fast - EXCELLENT FLEXIBILITY FOR ANY MOVEMENT: Four way stretch compression is designed for Freedom of Movement and to keep your Body Looking Slimmer.

But I have several different brands that are fleece lined and they all are made the same. They are made to go under clothing and not be bulky. **Q: Can the small size fit 2 year old** A: Too big for a two year old. **Q: Where can I find sizing chart? What are the ages/measurements of the garments?** A: At the bottom/ small, medium, large **Q: How do you tell what the size range is for small?** A: By sizing my son to my grand son they are one size off from each other ## Customer Reviews ### ⭐⭐⭐⭐⭐ My little one didn't want to take them off! *by E***R on January 24, 2023* I would give 10 stars if I could!
