Review on Long Johns Layer for Active Toddler Boys' Clothing - Stay Warm and Play Freely by Tyler Kota

A little big, but very thick and heavy. My daughter is 5 years old and wears 5t. We ordered 5, it fits perfectly. They were warm enough to wear under my daughter's fleece overall when we were camping in the Sierra National Forest in October when temperatures dropped to 38 degrees at night and our sleeping bags, my daughter didn't even mention that she was cold or was cold. Which was a great relief for me.
