This rope was developed in cooperation with the professional climber Tommy Caldwell. Its high sheath proportion makes it ideal for working routes or big wall climbing. Now also with a PFC- and PFAS-free Eco Dry finish in line with the UIAA standard for water-repellent ropes. The TOMMY CALDWELL ECO DRY DT 9.6 MM is made using the Duo Tec process, a patented braiding process developed by EDELRID for making bicolour ropes. In this process, the two halves of the rope are clearly distinguishable from each other by a pattern change in the middle of the rope. The centre of the rope is always clearly visible, which is a great advantage especially when abseiling, picking up ropes or estimating the remaining rope length. This change is achieved by a two-coloured band woven into the sheath. In the middle of the rope, the band automatically changes from one side (e.g. green) to the other (e.g. black). This gives the rope a permanent centre marking. The collaboration between climbing legend Tommy Caldwell and EDELRID has already existed for several years. Thanks to a lively exchange and valuable feedback, this cooperation has already resulted in some outstanding products. The common concerns and views also play a major role: safety, innovation, and sustainability. The latest result of this cooperation is the TOMMY CALDWELL ECO DRY DT 9.6 MM, a rope that is extremely robust thanks to its high sheath content and at the same time particularly sustainable thanks to the newly applied Eco Dry finish.
