Welcome to slackPro!

  To begin with, we would like to apologize for the construction on the site, but the site is still being reworked and expanded...
Please forgive us deactivated or german menuitems, temporarily not working hyperlinks and/or pages under construction, respectively pages that are still linked to their german counterpart. We are working hard to translate the missing pages afap!

Select language at the top right Please note, that the translation of the website to english is still in progress.
Please forgive us unavailable links or pages still in german and check back again. We're working hard to get it done quickly. Thank you and sorry for the inconvenience.

This website has been fully dedicated to longlining. While founding the company slackPro! in the spring of 2009, we found numerous websites on the subject slacklining, but none of them covered the subject longline intensively, or has even been dedicated solely to longlining. This has changed drastically up until today. Slacklining in general and its three main categories Trickline, Highline and Longline are now an integral part of society worldwide.

We were the first manufacturer (as far as we know), to offer and sell in large quantity ready to setup longline kits. The first full-blown slackPro!-Longline kit was sold on April 28th 2009 - a 100m kit by the way - regularily to a new german based customer over the internet. Today we are proud to have thousands of satisfied and enthusiastic longliners and highliners worldwide among our customers. Since the first kit we have continuously been honing the techniques and optimizing the safety, convenience and simplicity. The crowning result and the current head of the longline technique can be found in the slackPro!-Longline Kits Generation 10.

Our mission:

Longlining shall become popular
and shall be possible for everyone interested!


Please see for yourself, that with slackPro!-Methods and equipment every experienced slackliner even with a small budget is able to safely and easily rig an up to 100m longline, without prior longline knowledge, in a short time and all alone (without further assistance)...
