In "Batman Forever" (1995), the Batsuit is similar to the previous two films' costumes, except for the focus on a more anatomical design overall and a black utility belt instead of a yellow one. The "ears" on the cowl are also longer. One notable feature of the costume is a button on the utility belt which causes a fireproof coating to excrete from and cover the cape, allowing Batman to wrap it around himself as a shield from extreme fires, and a more 3-D bat emblem on his chest, but resembles the chest symbol from "Batman Returns". Also like in "Batman Returns", Bruce has numerous spares which he keeps in a large dome-like structure in the Batcave of this film. Dr. Chase Meridian, the film's love interest for Batman, mentions the appeal of Batman's suit as she runs her fingers across the chest section. After all of the regular Batsuits are destroyed by the Riddler, Bruce wears a prototype "Sonar Suit", which is 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.
