Petzl Flow 11.8mm Climbing Rope (2025)

Petzl's FLOW 11.8mm kernmantle rope for tree care. Flexible and lightweight, with a new mid-range diameter that blends flexibility and weight, and works in modern tree climbing devices. EverFlex technology ensures lasting flexibility and handling. Petzl has re-engineered Flow since it's initial launch with a new 11.8mm diameter, from the original 11.6mm. 

Every hank of Flow comes with a low-profile spliced eye, and now there is the option for 2 eye splices in the 45m length.  This compact eye splices can be installed through the links of the Zigzag or Zigzag plus, and glide easily through rings of a friction saver.

The new Petzl Flow is built for tree work. This kernmantle is well rounded and a great companion for your favorite tree climbing device.
