The item introduced here is the "Flight jacket TYPE-3". This item was born in 2016AW, which is called the "youth period" and is a very popular collection even in recent years.
It is a pullover type flight jacket with zips and buttons from the collar to the shoulders, and also zips on the sleeves so you can open the sleeves to show off the inner lining. It also has buttons on the sleeves so you can open them to show off your inner wear.
In addition, the items that came out in this "youth period" have added glamour by placing gold metallic buttons with the brand's initials, the letter S, stamped on them while taking over the military elements of those days.
