Sterling Fusion Photon DryXP Climbing Rope - 7.8mm

$224.99 - $299.99

Fusion Photon DryXP Climbing Rope

The Fusion Photon DryXP Climbing Rope is Sterling's lightest, thinnest rope that's dual-certified as a half or twin, and this dry-treated option is especially ideal for ice and mixed multi-pitches. The DryXP treatment is Sterling's first dry treatment to meet UIAA's standards for eliminated water absorption. Sterling achieved this by treating both the core and sheathe to repel moisture, and this treatment also amps abrasion-resistance if you're climbing rock.
  • Half or twin rope for climbing ice, mixed, or multi-pitch rock
  • 7.8mm diameter is Sterling's lightest and thinnest
  • DryXP treatment offers UIAA-certified water resistance

The perfect alpine ropes

I've put it through the wringer

Bought a pair of 40m about a year and a half ago and have used them from Colorado rock and ice to PNW glaciers. So far they are holding up well. Handling is really nice - supple right out of the box. For glacier travel, couloirs, or snowy ridge lines, use a single rope and the small diameter and light weight mean you won't have an annoying boa constrictor of coils around your neck. When things get more difficult it's super quick to tie in the second one and start climbing. 40m leads or raps and still more than two pounds lighter than my 9.5mm you can make your partner carry one ;) Dry treatment is effective; I've used these on late spring running waterfall ice climbs and they stayed pliable. For general mountaineering, ice, and alpine rock these might be the perfect ropes. Just make sure your belay device works with the tiny diameter.

rope up

Great ropes, right out of the package they feel supple and soft. They are very easily distinguished from each other with their bold color difference. Dry coating seems pretty effective in keeping them from freezing up too badly ice climbing. As far as using them for multipitch rock, they are great but realize that they will wear much more quickly than a standard 9.4+mm climbing rope. Still worth it to have them in the rope pile!

Confidence booster

Bought matching 30m ropes, which allows for significant versatility. This rope is great for ski mountaineering. It’s light weight, dry treated, and has a good feel. It is easy to just throw the rope in my bag on days were we have unknown challenges, raps, or semi technical/exposed ahead. TBD on durability.
