The Z5 is a suspension style harness, meaning that it has no rigid frame structure, but is supported via a series of suspension lines that route from inside the harness and up through the carabiner. The harness has three anodized aluminum spreader bars built in to the harness to relieve lateral compression forces as well as providing attachment points for the suspension lines. All major structural points on the harness are assembled and sewn using methods similar to the construction of skydiving harnesses. The result is a flexible and comfortable harness that folds compactly, is easy to repair, and its simple design allows for easy maintenance and safety inspection.
