A Canadian company says it has made a camouflage material that makes its wearer invisible.
Hyperstealth Biotechnology Corp, a Canadian camouflage design company, claims the technology, called Quantum Stealth, works by bending light waves around the wearer.
"The material removes not only your visual, infrared (night vision) and thermal signatures but also the target's shadow," Hyperstealth president and CEO Guy Cramer said in a statement on the company's website.
Mr Cramer said he could not reveal how the material bent light or show photos of it working "for reasons of security".
Photos published on the website that are described as a "mock up" show a woman lying on grass draped in a material that looks exactly like the grass around her.
Mr Cramer said the US military and two Canadian military groups had tested the material and could vouch for it working "without batteries, lights or mirrors".
He also claimed to be working with the US military to develop the technology further.
But don't put one on your Christmas list just yet.
Mr Cramer said he did not expect the material would be made available for sale to the public.
"Not in the near future unless the military decided to release the technology and I don't anticipate that will happen anytime soon," he said.
