Ask anyone to describe what Batman wears and after they describe the cowl, they will mention the utility belt. Batman's utility-belt is one of the most important aspects of the character. Combined with his prowess as a detective, his belt allows him the chance to compete with more powerful, and arguably useful, heroes. For some reason, Christopher Nolan has made a habit of overlooking Batman's detective skills, thankfully he has given the belt, and the gadgets it contains, plenty of screen time. This is proven during the film's only suit-up scene. Strangely absent is the expected shot of Bruce Wayne donning the trademark cowl. But that is what I love about this scene.
We are treated with a rare glimpse of how Batman's notorious utility belt is envisioned as a real-world item. We get to see the small boxes that store items we expect to see Batman use: smoke bombs, small explosives, etc. We get to see that he doesn't pull his Batarangs out of thin air, but in fact has a specific attachment that makes access to this crucial tool easy. But most importantly, it is implied that the belt is highly modular. This may not seem important at first, but in doing so, Nolan has further constructed a Batman that is as realistic as possible.
Beyond the belt, the audience is treated to a few obligatory shots of the bladed gauntlets and grappling gun. However, these items are little more that a giveaway. Nolan knows what his audience wants to see and the utility belt is exactly that.
