Question: Who designed the newest Batsuit?
About the article "Batman Begins", section "Batsuit".

Candidate passages:
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.
Jennifer Garner explains how Ben Affleck's Batsuit will be "silver/white plating attached to a black undercloth," and that the black undercloth will be seen at the joints.
She also explains how the suit will look "incredible," and just as good, if not, better than Christian Bale's Batsuit.  
The producers intended to create costumes based in reality to match the tone of the series while keeping consistent with traditional DC Universe continuity.
A majority of the art direction was led by Vietti, who established that the costume designs should not only reflect the physical needs of the wearer, but also his or her personality, with Bourassa incorporating these ideas into his designs.
In the case of Kid Flash's suit, for instance, the padding serves to reduce the force of impact experienced during skids and collisions, and the leathery texture stabilizes his "human cannonball" momentum.
Vietti cites the differences between the respective costumes of Aqualad and Robin to best illustrate what he calls "unique tailoring".
Aqualad's costume is designed for the purposes of quick movement in water, and is composed of a "slick and textureless material", giving the costume its "nearly seamless and shiny" appearance.
Robin's costume provides bodily protection (even against bullets) in the streets of Gotham City, and is padded and stitched with seams and sewn-in materials.
Batman's batsuit matches the extra stitching lines of Robin's outfit for similar functions, except that the batsuit is more military in style whereas Robin's costume is additionally influenced by athletic outfits to match his youthful energy. 
In "The Batman" (2004–2008), the Batsuit looks very similar to the costume from "Batman: The Animated Series", but has shorter 'ears' on the cowl to make the Batman look more like a "boxer", has claws on the fingertips of the gloves, a slightly redesigned yellow ellipse bat symbol on his chest, a more high-tech computerized utility belt linking to the Batcave's computer system called the "Batwave"; The belt's buckle can be removed and used for several purposes, such as for a tracking device, for controlling the Batmobile, the Batbot, or as seen in "The Cat and the Bat" fly remote-controlled batarangs.
It also has a longer cape that, just like the DCAU costumes, sometimes covers his entire body below the head.
In the episode "Fleurs Du Mal", it is shown that the suit is linked to the Batwave, to monitor his physical and mental activities.
Despite this regular default Batsuit, Batman uses some other variations of the Batsuit as well in the series to tackle certain situations and villains.
In the episode "Traction", the Batman is badly injured by the immensely powerful Bane, due to which he is forced to build a prototype exo-skeleton called the "Batbot" to battle the villain.
The Batbot is controlled by Bruce Wayne while sitting inside its cockpit.
It is shown to possess superhuman strength to match that of Bane, along with enhanced levels of agility and endurance.
It has two turbo retro-thrusters for flight on its back as well.
The Batbot is also shown to be controlled via the Batman's utility belt (for example, in "The Cat and the Bat" episode).
In the episode "The Big Chill", when Mr.
Freeze defeats the Batman in their first encounter, the latter's butler Alfred coats the Batsuit with a special white weather-proof material, that can withstand sub-zero temperatures and can be used by the Batman to camouflage himself in snow.
It covers the Batman's facial part as well, which is usually the only exposed part of his regular Batsuit.
Additionally, this arctic Batsuit is shown to be armed with retractable ice skates in the boots and two flamethrowers attached on either side of the waist.
Also, the blades on the Batman's gloves emit high electric sparks to melt any ice in his path.
The arctic Batsuit reappears in the episode "Fire and Ice", and is depicted to sustain heavy amounts of damage but protects its wearer, when the villain Firefly maneuvers the Batman into a fuel tanker that is about to explode.
The Batman survives, but injures himself and has the suit damaged.
In the episode "Swamped", when the Batman has to battle Killer Croc, he uses a special hydro Batsuit, that does not get wet or allow water to enter it.
It is totally black in color, and the Batman somehow sheds or retracts his cape in his suit when he goes underwater to battle Killer Croc.
In the movie "The Batman vs. Dracula" (2005), Batman briefly extended the design of his utility belt to his shoulders and chest for carrying a vast number of vampire-fighting gadgetry such as garlic bombs, garlic-treated batarangs, and vials of vaccine made to counteract a vampiric virus spread from the vampire lord Count Vlad Dracula.
The extension of the belt would also create a shape of a cross, which is commonly known to be able to ward off vampires as they have an aversion to all of the Christianity icons, including Christian crosses.
When arsonist Garfield Lynn's transformation from Firefly to a nuclear-powered Phosphorus in "White Heat", Batman designed a black NBC suit, built by Alfred, to protect himself.
On the episode "Artifacts", it is shown that, decades into the future, an elder Batman would adapt a simpler Batsuit resembling of Frank Miller's "" graphic novel.  
Other media appearances.
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.
