The design is incorrect. There is no space below, but there is a stack ahead. These are pants for girls and the straight cut will not work if girls are over 5 or 6 years old. Almost sent these pants back because the waist lining is broken and the seam line from hip to toe is in the wrong place. I'm not sure I would buy them again but I think the thickness is good if you don't need outdoor winter pants.
