We start with the concepts and a little history.
Cartridge belts (so called special pockets on the Circassian intercepted braid) - is the main feature of these cloaks, not allowing them to mix with other clothing. They inserted hermetically sealed cupboards, often made of bone, which fill in the pre-measured powder charge and bullet wrapped in a cloth, designed for a particular gun. With the Arab «hazr» translated as "finished," that is consistent with the intended cartridge belts - there were pre-prepared materials to charge the matchlock or flintlock.
Make it could be at full tilt during the battle, which was very important when using a single-shot weapon. The cylindrical canisters could be placed, including paper cartridges, capsules, dry chips for quick kindling a fire, and other items that are in any conditions should remain dry.
Gazyr were perfectly suited for combat operations in mountainous conditions regardless of the weather. Gunpowder in the canisters did not get wet, if the shooter moved standing, on horseback and even fell in the mud or water.
