Both are warm pants with fleece lining. The black pants show signs of wear, such as pilling, so please check photos 10-14. The gray pants are in good condition. They have large pockets and are easy to use. How about them for cold winter days? Thank you. #KidsWinterPants #KidsFleeceLinedPants #BoysBlackPants #BoysGrayPants Gender: Boys Color: Gray系 (Gray-based) Pattern/Design: Solid Pant Length: Full Length Season: Winter
