The E650DQC/UBL DuraFlex™ harness with Elastomer has a 1-3/4” stretchable webbing which is made from a mix of 85% polyester and 15% urethane elastomer and conforms to the shape of the wearer for a snug fit. Although easy on the body, the system has undergone ASTM (50) fifty-hour salt spray tests and is rated at 400 lbs working load with the straps rated at 5,000 lbs tensile strength. The leg and chest straps are fitted with Millers quick connect system and the two hemispheres snap in place with friction buckles on the shoulder straps. A sub pelvic strap keeps the base together while a back pad with additional padding over the D-ring keep the user from feeling stresses often related to wearing harnesses. The full mobility provided by the stretch straps make the E650 range suitable for climbing and descent.
