Zephyr™ Performance Systems help train the most elite teams in the world, the U.S. Special Forces.

Members of special forces units use Zephyr™ Performance Systems to increase the effectiveness of their training regimens and candidate selection. They know firsthand how the leading physiological and biomechanical monitoring systems help give them an edge.

NASA uses Zephyr™ Performance Systems to combat motion sickness caused by weightlessness. Already it has helped 65 percent of those undergoing training suppress motion sickness.

This is important because astronauts can’t be distracted or incapacitated. And soon missions won’t be measured in weeks or months, but in the years it takes to get to Mars and back.
