Jackson Gordon is an industrial design student at Philadelphia University and he also runs a Facebook page Armatus Designs. It's on here that you can see his Combat Batsuit.
Gordon has been working on prototypes for the suit since last September and used Kickstarter to fund its completion. He finished it recently and wore it as his cosplay to Katsucon to show it off and test it out.
The finished suit and helmet, made from Kevlar and silicon molds, weighs 25 pounds and 3 pounds respectively. "It sounds like a lot, and when you have it in a bag over your shoulder it weighs a ton, but when you are actually wearing it, you barely feel it." he told USA Today.
Although the suit won't stop a bullet, it can protect from punches, kicks, and knives as you'll see in the stress test videos above and below.
From USA Today:
Gordon had already made a Batsuit before, but that was costume solely based on aesthetics. He says he wanted this project to be a combat suit that could withstand battle without inhibiting movement. Gordon — who has a black belt in Kung Fu — isn’t shy about throwing a kick or falling into a split to demonstrate the flexibility of both the suit and himself.
