USAF current issue air-crewmen harness.
It is vital to select a harness that you can get out of, even when it is supporting your weight. This is to prevent you being “hung up” in an aircraft unable to unclip.
These harnesses have front positioned, 2 independent buckles for further safety. The buckles are specially designed so they cannot be snagged and opened.
The front positioning allows you to leg it in the event of a fire.
