This is the GUIDE SHELL MOD COEXIST, a standard model from CMF OUTDOOR GARMENT. The color is GREIGE. The size is L. For reference, here are the size details from the website: Length 76.5cm, Width 160cm, Sleeve Length 90.5cm It has zippered ventilation under the arms for easy temperature adjustment. The sleeves can still be removed from the switching part. Also, from this season, the stand collar has been changed to a stowable type, and this shape is continued this season. I have been wearing a different color, and this one has only been tried on indoors. For your reference, I have attached the official website address. http://losthills-store.jp/?pid=182464866
