Flak Jacket

The flak jacket (tactical vest) is usually worn by Chūnin and Jōnin over their normal clothes in most villages, although the design varies among the villages. Although they are called jackets, they look more like a vest, or other similar garments. The jackets are among the most iconic pieces of shinobi equipment. Along with also being a ninja soldier icon as well. Most of them have pockets, which can be used to store scrolls and also allow a ninja to access them with only one hand, as seen with Kakashi's case when he normally does this secretly to extract a kunai.

Each village has a different versions of this:
 * Konohagakure ones have three scroll pouches on each side of their chest for scrolls, medicine, and other ninja tools. For protection they include a neck guard and extra padding over the shoulders. They also come with pockets, though older ones and the ones in other villages have none.
 * Sunagakure have more versatile jackets that may or may not include shoulder padding, shoulder guards, neck guards, and scroll pouches over their stomachs, or none of these.
 * Iwagakure has a large pouch over their stomach or lower back of the vest only.
 * Kirigakure versions come with and without a neck-guard but has elongated padding over the shoulders.
 * Kumogakure has a rather utilitarian version with its only distinctive feature being that it has only one strap to hold it in place.
