Evolution Duetto Dry XP Half Rope

It only makes sense for half ropes to have reliable dry treatments because climbers generally climb alpine or ice with them. The Evolution Duetto DryXP Half Rope features Sterling's most recent dry treatment that actually complies with UIAA's water-resistant standards. DryXP practically eliminates water absorption and greatly enhances abrasion-resistance for more reliability when you're hundreds of feet in the air. With 8.4mm diameter, the Evolution Duetto is a mid-range half rope—not too fat, nor too skinny—just right for experienced climbers starting to use half and twin ropes.

  • Half rope optimized for ice climbs, alpine routes, and multipitch
  • 8.4mm is a mid-range diameter for half and twin ropes
  • DryXP treatment meets UIAA's standards for water-repellency
  • Item #STE001Y

Best Value in a 30m dry rope.

I've used it once or twice and have initial impressions

Needed a couple 30m dynamic dry ropes for some Alpine touring 2018. These were affordable and fit the bill exactly. Bomber and highly recommended as best bang for the buck.


Is this really a twin? Sterling's website lists it as a half?

Agree with Dennis' question. This is almost certainly a half rope. Sterlings twin series is the fusion photon. I've owned both, and unless they've radically redesigned their lineup he duetto is still a half rope. Backcountry, you need to correct your listing.

I have sterling evolution duetto 8.4mm dry ropes from 2015, same purple and orange colors as the photos here, and they were called halves then and I've always used them as halves (clipped individually to carabiners). I wondered if the certifications had changed, but like Bogdan P said, the website still says half rope.
