Tubbs wrote a review of Petzl Zephyr 10.3mm Climbing Rope- 2010 on October 24, 2009
I have been climbing lightly on this for 2 years now, lead sport and occasional top roping. I treat ropes very gently. This rope has never sat in dirt and is coiled in a rope bag 99% of the time when part is touching the ground. I have only had to wash this rope once; it is in great condition. The dry coat really helps it repel dirt and keeps it easy to handle in rain and sleet when everyone with a brain is indoors. Lead falls on it still feel spongier than falls on my friend's 9.8 ropes when following. This rope does carry a slight weight penalty for its highly dynamic nature. While researching similar ropes the only one more dynamic was a beal rope, so this rope adsorbs falls really well, but will stretch accordingly far. The mid and 6-meter-from-end marks are great for rapelling. This would make a great first rope, not so great for leading harder climbs because of its weight.
