Filmation and Hanna-Barbera.
In the various superhero animated series produced by Filmation and Hanna-Barbera, including "The Adventures of Batman" (1968–1977), "Super Friends" (1973–1986) and "The New Adventures of Batman" (1977), Batman's costume has consistently resembled the blue and gray Batsuit of the Silver Age comics from the 1960s and 1970s, and the "New Look" version of the batsuit. 
In the various superhero animated series produced by Filmation and Hanna-Barbera, including "The Batman/Superman Hour" (1968–1969), "Super Friends" (1973–1986) and "The New Adventures of Batman" (1977), Batman's costume consistently resembles the blue and gray Batsuit of the Silver Age comics. 
The filmmakers intended to create a very mobile Batsuit that would allow the wearer to move easily to fight and crouch.
Previous film incarnations of the Batsuit had been stiff and especially restricted full head movement.
Costume designer Lindy Hemming and her crew worked on the Batsuit at an FX workshop codenamed "Cape Town", a secured compound located at Shepperton Studios in London.
The Batsuit's basic design was a neoprene undersuit, which was shaped by attaching molded cream latex sections.
Christian Bale was molded and sculpted prior to his physical training so the team could work on a full body cast.
To avoid imperfections picked up by sculpting with clay, plastiline was used to smooth the surface.
In addition, the team brewed different mixtures of foam to find the mixture that would be the most flexible, light, durable, and black.
The latter presented a problem, since the process to make the foam black reduced the foam's durability.
For the cape, director Christopher Nolan wanted to have a "flowing cloak... that blows and flows as in so many great graphic novels".
Hemming's team created the cape out of their own version of parachute nylon that had electrostatic flocking, a process shared with the team by the British Ministry of Defence.
The process was used by the London police force to minimize night vision detection.
The cape was topped by a cowl, which was designed by Nolan, Hemming, and costume effects supervisor Graham Churchyard.
The cowl was created to be thin enough to allow motion but thick enough to avoid wrinkling when Bale turned his head in the Batsuit.
Churchyard explained the cowl had been designed to show "a man who has angst", so his character would be revealed through the mask.
Seen only twice in the series, the Exosuit is donned by Bruce in an encounter with Inque, who had kidnapped Terry and was holding him hostage.
It is a suit of heavy armor with retractable plates that enhances the survivability of the wearer, boosting their physical strength and resilience to superhuman levels, at a level greater than that of the Batsuit.
When retracted, Bruce was able to wear a trench coat over it and not look like he had any considerable increase in body mass.
Bruce created the Exosuit years earlier in light of his increasing heart problems, as a possible replacement for the Batsuit.
However, during testing, using the suit nearly gave him a heart attack and he was forced to abandon that option.
Understandably, Bruce will only use the Exosuit in dire circumstances.
It is featured in the episode "."
Taking advantage of the computer generated imagery used to create the show, the Batsuit worn in "Beware the Batman" is more detailed than previous versions.
Like the suits seen in most of the live-action films, the new Batsuit is entirely black and sports a raised bat-emblem on the chest without the yellow-ellipse, as well as a more helmet-like cowl, and it is very similar to the outfits from "The New Batman Adventures", "Justice League" and "Justice League Unlimited".
The suit's utility belt was also redesigned for the show, and an actual model was built by Glen Murakami in order to make it as realistic and practical as possible.
