The 220cm slackline slings are ideal for primitiv and ratchet installations.
They allow to set the equipment on the trees.

With their 5cm width, the support surface is large. This allows even less damage to the bark of the trees, even if tree protections are still recommended.

 All our slacklines are made in France 

And the preparation of your slackline orders - from the design, to the sewing, to the packaging - is done in our workshop near Annecy (France - Haute-Savoie - 74).

2 models are available:

  • simple model with 2 loops : to attach a carabiner or a ratchet in a basic way

longe easy slackline

  • multi model with 3 loops : used for a primitiv system (with carabiners), to attach directly the primitiv multiplier on the same sling. Simple, fast and efficient without having to add other elements like a riggin plate

Advice for use

  • For all kits of 50m and less. For longline over 50m long or highline or trickline, prefer round sling
  • Not ideal for a lark's head installation
  • Even if their 5cm width damages less the bark of the trees, we can only recommend the use of tree protection. Both to protect the trees and your equipment (resin, wear, etc).
  • The equipment can remain installed for 2 or 3 days maximum. Ideally dismantle it after each use.
  • Store your material, dry and away from humidity, like all textiles. Click on the link for more details on how to maintain and store a slackline.


  • Installation of more than 50m
  • Pulley system for tension (prefer round sling)
  • Do not attach to street furniture (poles, lampposts, etc.), nor to the posts of your terrace or balcony! They are not at all made to undergo horizontal stresses!

  • No Jumpline/Trickline. You want to practice Freestyle ? Look out for Freestyle equipment like the Trickline kit.


Slacklining and more particularly Highline (in the void, secured by a harness) are sports practices that have no normative or regulatory framework for the manufacture of the material as well as for its installation.

This is why we do not guarantee our own equipment for highline use.
Our products are tested within our company and independent laboratories (mentioned on the product page) via a process that evolves with practice.

These resistance tests have no legal value, they aim to ensure the safety, resistance and comfort of use of our equipment - in the context of our practice.

It is the responsibility of the practitioner to choose the equipment with the appropriate resistance and to have the necessary experience to adapt the installation to his practice.
And to use appropriate equipment to secure oneself if necessary, such as PPE equipment (climbing gear, ropes, etc.).


  • Do not install your slackline across a path, trail or place of passage
  • Do not install your slackline more than 2m from the ground without securing yourself with PPE equipment
  • Practice on grassy or cushioned ground free of any protruding objects or objects that could cause injury
  • Do a back up = secure your tension system
  • Never use a ratchet for highline practice
  • Never install your slackline on urban furniture (benches, lampposts, barriers, etc.)

Safety regarding highlining

It is the responsibility of the practitioner to use appropriate equipment to secure oneself if necessary, such as PPE (climbing equipment, ropes, etc.).

In NO CASE is this equipment designed to secure itself. For the lifeline - called backup - we advise to use only PPE standard material (climbing material, ropes, etc).
Unless expressly mentioned, no slackline element can be considered as PPE (personal protective equipment) for sports and leisure activities
