Profile must read Size 100 Baby GAP denim pants. These pants have a warm lining, perfect for winter. The left pants were only worn 3 times when going skiing in mid-winter. They seemed to be very warm with the fluffy lining. The right pants were given to me by my sister, and there is a faint stamp of a name inside, but it was originally light. They were worn less than 5 times. My son tends to get hot easily, so he only wore these once when going skiing. Adjustable waist with elastic. These are used items, so please refrain from purchasing if you are sensitive to used items. Brushed fabric
