Great quality! It was just thick enough that I felt confident my baby was warm in the cold weather, but not thick enough to make her uncomfortable and pull at them. I had them under pants and they weren’t too bulky.I’d say it’s pretty true to size, but I’m the type of person that throws anything in the washer and dryer and it did shrink a little. Knowing that after the fact I probably would have sized up, but they still fit well enough with a couple tugs since they’re stretchy. Worth it to keep my girl cozy!
