Petzl Zephyr 10.3mm x 70m dynamic rope

10.3mm single rope with Duratec Dry treatment

The ZEPHYR is our toughest all-around rope. The 10.3 mm diameter offers additional friction in belay/rappel devices for more control, and is extra durable. This workhorse rope is great for people just getting into the sport or for those who want the increased longevity of a thicker diameter rope. 

• Duratec Dry treatment helps prevent the rope from absorbing water – which can weaken a rope and make it difficult to handle in freezing conditions. Before a Petzl rope is constructed, the core and sheath strands are individually treated, providing water repellencty in case you find yourself in a deluge, snowfield or on a dripping ice chandelier. 
• All Petzl ropes are butterfly coiled in the factory and are ready to use straight out of the package. This coiling method means no more tangled mess when you first use your new rope. Gone is the tedious operation of carefully uncoiling, flaking and reflaking your new rope, only to end up with annoying kinks. With a Petzl rope, just tie-in and start climbing.
• To help facilitate descents, the middle of each Petzl cord is marked with a black bar. Even with this marking, it’s sometimes a good idea to tie a knot at the end of the rope as an additional safety measure.
