Petzl Airline is high visibility, snag-free throw line made from 100% Dyneema SK75, pre-stretched and tensile-set and then treated with a vinyl coating. Compact design glides smoothly over branches which means you can use lighter throw weights for greater accuracy. Petzl Airline has a genuine Dyneema sheath for added toughness and abrasion resistance woven over a solid EVA core. This construction helps the line stay round and glides effortlessly through the tree. Petzl Airline is very light, so you don't need a hefty throw weight. Petzl Airline is 1.8mm in diameter with a tensile strength of 250 kg. For advice and guidance on throwing techniques, download a copy of Mark Adams 'Slick Tricks' below.
