Warmth is wonderful!
I am a 22 year old female who happens to be a size 2-4, or kids 14. These are a wonderful mid layer or warmth. I’m actually wearing them in my 60 degree home right now as an only bottom layer and feel just fine. Whether you by these for your child or yourself, know you’re making a warm choice. Fabric feels sturdy and gives nice stretch. These fit like a glove.
Best first layer ever
My 3 year old goes to an outdoor preschool in the PNW. These are his chosen favorite. They are warm, thick, and have a nice stretch to them also while being light weight. They keep him toasty warm, even on the coldest and rainiest of days. They are so comfortable that after preschool he doesn’t want to take them off. He has even asked to wear them to bed before. We just purchased another pair. Worth the investment!
Well made and warm
My 6 year old son is on the small side so I got size xxs. Fits him perfectly and kept him warm and comfy during his ski lessons.
