The E650-4/UGN DuraFlex™ 650 series harness with back D-ring & tongue buckle is made from patented DuraFlex webbing which is made from 85% polyester and 15% urethane elastomer. This gives the 1-3/4” webbing strength with flex so it supports comfortably while conforming to almost any body shape. The system is rated at 400 lbs working load and connects with friction buckle shoulder straps, tongue buckles on the legs and a mating buckle across the chest. Because comfort is important, Miller has included a soft padding at the back cross over so that the sliding D-ring can’t dig into the wearer. This model comes in green with black trimming in a universal size with a lanyard ring and belt loops. The E650 DuraFlex range is also suitable for climbing and descent.
