This is the RS TAICHI RSJ720 softshell jacket. The hood is removable, and the inner jacket can be worn separately. Size: M Back Protector: Shoulder and elbow protectors, as well as a back foam pad, were originally built-in. However, the back foam pad has been disposed of, and an aftermarket one was used. Therefore, it is not included in this listing. Please be aware of this. Chest Protector: Since I was using the separately sold TRV067, I will include it with this listing. It's a separate-type protector, making it easy to use.
