The futuristic ensemble consists of three sets of miniature jet engines attached to the arms and the back.
Richard Browning, a 38-year-old oil trader, had been secretly experimenting in his garage for 18 months, before he figured out the optimal number and position of the jet engines that allows him to fly with a minimal amount of equipment.
"The human body is very good at being trained to do specific things, and it's a useful structure, and the human mind is a pretty amazing machine," Browning said.
Piloting the device takes quite a lot of personal strength and body coordination, said Browning.

There is no steering mechanism, and speed and direction can be adjusted only by changing the direction of the engines' thrust, solely using upper-body strength.
"You have a trigger at your right hand, which controls the arm engines, and you have a trigger at your left hand, which controls the rear engines," Browning told the 'Live Science'.
Currently, Browning can stay in the air for up to 10 minutes using the exosuit. He has kept his experiments at a running speed of about eight kilometres per hour and an altitude of only one to two metres above the ground.
Eventually a user could fly over 100 kilometres per hour and to an altitude of about 100 metres, Browning said.
