Light and nimble. The Sterling Duetto XEROS 8.4 mm x 30 m dry rope is a midrange half and twin rope that's ideal for long, wandering routes, run-outs, ice climbs or sketchy trad leads.


  • UIAA Dry certified built with Sterling XEROS technology
  • Part of the nylon filament manufacturing process, XEROS technology is a permanent core and sheath dry treatment that ensures individual yarn fibers are water resistant
  • Since it's built into the core and sheath, there's no tacky or sticky coating to pick up dirt
  • XEROS is PFOA-free and reduces waste, energy use and labor, all without a price premium
  • UIAA 101
  • CE EN 892
  • 95% of the raw rope fibers at Sterling get made into finished products; remaining waste gets recycled or upcycled into non–life safety products
  • Send your used Sterling dynamic rope to the Sterling recycling department so the materials can get a second life; they also accept non-Sterling dynamic ropes
  • Rope manufacturing facility runs on 100% renewable energy
  • Sterling offsets 100% of their carbon emissions by purchasing carbon offsets from Climate Neutral and Arbor Day Foundation

Made in USA.

Note: Half and twin ropes are designed to be used in matching pairs (size, length and brand should match). Using a mismatched pair can cause excessive wear on the ropes, exposing you to a higher risk of rope failure. Never climb with only 1 half or twin rope, unless it has also been rated as a single rope.
