Constructed with a Dyneema sheath and featuring excellent abrasion resistance and core/sheath bonding, the Petzl AIRLINE will maintain a good, round cross section. This ensures good rope glide through a tree or complex industrial trussing. Checking in with a diameter of 2.2mm, this throwline is easy to handle and exceptionally light to pack. Combine with the Petzl JET throw-bag and the Petzl ECLIPSE bag for a complete throwline kit.
