Exploration depends on people -
and the equipment that
protects and enables them.
At Razzor Tech we focus on
human-centered performance: Intuitive operation, realistic mobility and reliable function under harsh conditions. Because the future of exploration will be shaped not only by technology, but by the humans who operate it.

Mobility systems for human-centric spaceflight training: Analog astronaut suits and pressurized neutral-buoyancy training suits - built for fidelity, efficiency and scale.
