9.8 Crag Dry Rope

The Mammut 9.8 Crag Dry Rope is a 9.8 mm single rope with a PFC-free UIAA Dry finish, which Mammut describes as durable and versatile. It is the rope for endurance laps at the gym and days on rock where you tick route after route. We stock it in Vibrant Orange-Lavandin, in 60 m and 70 m.

Who it's for

All-round climbers who rack up mileage, from someone redpointing their first grade-20s to a climber just starting out. Mammut rates it six out of six for sport climbing. Picture a four-day Easter trip to Arapiles or the Grampians, ten routes a day, a shower or two passing through: the Dry finish is made for days like these.

Diameter and what it suits

At 9.8 mm the Crag Dry is certified as a single rope, one strand for lead and top-rope. Mammut says the 9.8 mm diameter makes it ideal for gym endurance sessions or volume days on rock.

Handling and impact force

• Impact force: 8.1 kN
• Stretch on first fall: 29%
• Static elongation: 6%
• Sheath proportion: 38%

Impact force is the peak force recorded in the standard UIAA drop test; a lower figure means a softer catch; static elongation is the stretch under body weight, the give you feel when lowered off.

Dry treatment

The Dry finish is what turns this into a rope for real outdoor mileage. Mammut's PFC-free UIAA Dry treatment repels water and dirt, keeps water absorption under 1.5% in the UIAA test, and gives the rope extra abrasion resistance; Mammut says treated ropes last longer and are great in wet conditions.

Fall rating

The 9.8 Crag Dry Rope holds 8 UIAA falls with an 80 kg mass as a single rope, and conforms to EN 892:2012 + A3:2023.

Length and weight

Both lengths weigh 64 g per metre. The rope comes packed tangle-free, ready for the first route without uncoiling.
