This mod adds a bag from GTA IV to GTA San Andreas. It replaces the four bandanas that are tied at the back of the bag model. They cost $25 and can be worn with any outfit in the game. The bag explains where CJ keeps his weapons (except for the bazooka). Also works in cutscenes.
This mod basically changes clothes, but the category doesn't fit, so I adapted one of the categories for my mod.
The mod is not mine. I found a black travel bag mod and put them on as a bandana replacement and made 3 more color choices.
A bonus to the mod is another text file that replaces the name "Hats" with "Hats & Bags" and adds the names of the bags in the store list + backup file.
