ISA highline ring and leash Certification LogoHighline Leash – 320cm | ISA certified

SLACKTIVITY’s Highline Leash was tested according to the safety standard ISA 37, by the International Slackline Association, wich makes it the best choice for securing yourself to a highline.

A dynamic Edelrid climbing rope (Hummingbird Pro Dry 9.2mm) is threaded through a 20mm Nylon tubular webbing to create a redundant leash with a tight fit. The webbing has a soft feel to it, which makes it easy to climb after a leashfall and to untie your knot afterwards. The black edges are great for detecting twists in your Highline Leash, so that a whipper does not send you spinning around.

The length of 320cm is perfect to tie a figure-8 knot on your harness and to the leash ring, and still have sufficient length to walk without getting bothered by the leash.

The SLACKTIVITY threaded Highline Leash may or may not include one or two certified highline rings. Every single ring is preload tested to 6kN and is ISA:37 certified as well. It is lightweight, strong, and has a really smooth surface to prevent any damage to your line. Please be aware that highlining can be a dangerous activity if done incorrectly. We recommend you to learn from experts before starting by yourself.

You can choose between buying only the leash, buying with one or two rings.

Tip – one vs. two rings

Tape two rings together. Two rings glide more easily over the tapes of your highline rigg. The certified ring can be used individually on a leash but, at the moment, it is common to use two rings together. It is a matter of redundancy but from the safety perspective, with certified rings, not necessary anymore. If you still want to use 2 rings – it is recommended to tape them with electro tape together.
