Boys size 4t polo ralph Lauren sweat pants/joggers

These are two pair of polo, Ralph Lauren size 4T sweatpants/joggers one is quite a bit longer than the other. It’s just the type of style they are. The yellow pair does have staining to the knee, which is shown in the photo and also light staining throughout that may or may not come out. The gray ones have some small piling in the seat area, but other than that, no notable signs of wear. These are very warm and thick.
