Used when my child was in high school. The size is 3L. It's large. My child, who is 184cm tall, used it. Usage period was about 3 years. The back of the jacket has a gusset and can be adjusted to accommodate a backpack. Washed. The case is torn, so it's not included. #Raincoat #Rainwear #Raincoat #HighSchoolStudent #BackpackCompatible
