an iridescent silvery-black and more armor-like. This new Batsuit utilizes lenses that slide automatically over the cowl's eyeholes to display a sonar-generated image of Batman's surroundings to him, allowing him to see with more accuracy in extreme darkness or glare. The use of this suit in the climax of the film, allows Batman to smash the Riddler's Box-device and save both Robin and Dr Meridian, which otherwise would have been impossible with the standard Batsuit. The Batsuits in this film were created from a less dense mixture of foam rubber, which resulted in much lighter suits and allowed more flexibility for Val Kilmer and the various stunt doubles, while increasing durability. More than 100 Batman and Robin costumes were created to allow for the range of stunts, from underwater scenes to scenes involving fire and extreme fighting. The "sonar" Batsuit was subsequently used by Christopher Nolan when auditioning actors for the lead role in Batman Begins, and was worn by Christian Bale and Cillian Murphy among others.

This film also added pop-out ice skates to the costume's boots. The basic Batsuit of this film is also noticeably more blue than black in color tone, including the ellipse around the bat symbol instead of the yellow ellipsed bat symbol from the last three films. A second, more elaborately detailed costume (a silvery Arctic version) is worn by "Batman" during the film's climax against Mr. Freeze, which is identical to the prototype "Sonar Suit" from Batman Forever, but in blue with silver accents. As in Batman Forever, the basic Batsuit of this film also features nipples and an enlarged codpiece. While Bruce is giving Alfred his medicine, he wears the same prototype "Sonar Suit" from Batman Forever, minus the cowl and gloves. The Dark Knight Trilogy (2005–2012)Batman BeginsThe Batsuit in the reboot Batman Begins (2005) is given the most complete description ever seen in a Batman film and the comic books. Derived from the Research and Development Program within Wayne Enterprises' Applied Sciences Division, the suit is described by Lucius Fox as a Nomex survival suit originally intended for advanced military use but was considered to be too expensive for the United States Army
