Petzl Anneau Sling

Polyester is highly resistant to abrasion and UV degradation, making it an excellent choice for a workhorse sling that sees frequent use in outdoor environments. While it is slightly heavier than Dyneema, it offers superior durability and a more predictable feel when handling.

The 60 cm length is standard for extending quickdraws to reduce rope drag, while the 120 cm and 150 cm options are better suited for building equalized anchors or slinging natural features like trees and boulders. If you are unsure, a mix of 60 cm and 120 cm slings covers the vast majority of sport and trad climbing scenarios.

While the Anneau is rated for 22 kN and is structurally sound, it is designed as a general-purpose sling for anchors and extensions rather than a dedicated Personal Anchor System (PAS). If you need a tether for rappelling or cleaning anchors, a dedicated adjustable PAS is generally safer and easier to manage.

Yes, the 16 mm width strikes a balance between being easy to grip and lightweight. It is wide enough to handle comfortably without feeling bulky or difficult to untie if the sling becomes weighted.

Retirement depends on frequency of use and exposure to elements, but you should inspect it before every climb for signs of fraying, discoloration, or stiffness. As a general rule, even if it looks fine, you should retire any textile climbing gear after 10 years of storage or sooner if it shows significant wear.
