Uses the same technology and basic design as the Quartz performance rock harness with a few slight modifications that makes this harness fit the specific sensitivities and anatomy of the female body. Softer swami materials with minimal interior stitching make it extremely comfortable against exposed skin. The space between the waist belt and leg loops has also been decreased to fit the female form. Constructed from 4 mm super-perforated EVA foam. Features three patented systems including Auto Fit leg loops, No Twist belay loop and Flat Link elastic in the rear.
