Super soft, great material and made thermal sets.
Ashley del—December 11, 2025✓ Verified purchase
These fit amazing for my 4 and 5 year old boys. The material is so nice. To keep them warm under their clothes for the winter. They are very durable. Both my boys I got a size small. They are both almost 50lbs. And 51lbs. And both 3 and a half foot. They aren't super snug. And made woth soft soft material. My boys loved them. And I want me (mom) a pair. Lol. Read more

Warm, thin thermal set
Erin—January 13, 2026✓ Verified purchase
Love these thermals for my son. They kept him warm playing in the snow and are thin enough to go under pretty much any clothing, while still keeping you a comfortable temperature. Good material, not sweaty. Read more

LOVE these
Kayla Beasley Farley—March 27, 2025✓ Verified purchase
These are soooo soft. My son is autistic & plays on the soccer team. He (me as well) thinks all leggings or pajama pants type stuff is to “scratchy” or weird. These are thicker than most leggings, but they are a smooth cotton feel. Not like most thermal fabric, it’s not silky or tight. These have stretch, they don’t make you overly hot once you start running. Quality is great, fits true to size. We got black, love the stretch room & material. Read more
