Tendon Master 8.5mm Half/Twin Rope - Complete Shield Dry Treated

The Tendon Master 8.5mm Half/Twin Rope balances durability, handling and weight for trad and alpine climbing. Certified for both half and twin systems and fully dry treated, it is the sensible choice for climbers who want a mountain rope that lasts.

At 8.5mm and 46 g/m it is a touch thicker than ultralight ropes, and that buys you a high 46.8% sheath mass for abrasion resistance and a longer working life on rough rock. Complete Shield treats the rope with TEFLON ECO particles to create a near-impermeable layer over both sheath and core, resisting water and dirt to the UIAA 101 standard. Handling is confident, with 0.1% sheath slippage and 30–32% dynamic elongation for effective fall absorption. Choose it over a skinnier rope when your routes are long, gritty and repeated season after season. Available in green or blue, from 30m to 70m.
