These are gray and black pants. The gray ones are fluffy inside and very warm. The black pants are regular pants. They were used for changing clothes at nursery school, so there are no pills, scuffs, or holes, but they are used items. Please refrain from purchasing if you are concerned. Names are written on them. The gray pants are Uniqlo. The black ones are from some other manufacturer. I think they can be used by both boys and girls. My daughter wore them. #Unisex #100cm pants
