This belt bag is literally a belt bag. You cannot even call it a sling bag. The Half Moon bag by A.P.C is made from genuine leather, metal trims, metal zippers, and twill lining. It has a main zippered compartments with internal slip pockets for organization. It is called half moon due to its shape. It has the A.P.C. logo on the front. It can be adjusted via buckle. It can be carried only one way, attach it as a belt. It comes in two different colors, red and black costing at $455. It is now available.
I like the look for this bag but AP.C. should have made the straps be removable or change the way it is attach so it can be carried as a sling.
