25 mm webbing specific for longlining and highlining.
- Material: polyamide nylon, Minimum Breaking Strength 32 kN*;
- Weave: hybrid, flat central body in polyamide and stretchy, puffed outlining for extra pillowed edges;
- High-stretch: 13% @ 10 kN, excellent for bounce-lines;
- Abrasion resistance: dense weaving increases abrasion and water resistance;
- Anti-twist: two different coloured sides, in order to avoid twists during installation.
SELECT LENGTH BY METER or a FIXED LENGTH (SPLIT) that comes a WITH SEWN LOOP ON BOTH ENDS.
*MBS by manufacturer - Find all differently tested MBS values in the PRODUCT DETAILS below.

DONKEY ideal for Longline and Highline
A 100% Nylon polyamide, bouncy webbing with new, extra soft edges. DONKEY is a line somewhat similar to our JOKER but overall completely different, it's great for trick-highline practice, with an innovative tubular edge technology. Perfect also for Longline set-ups to surf or simply walk for a while.
Play your donkey
No matter if you are an expert or rookie, the DONKEY webbing will make you find love at first sight.
DONKEY is a quite heavy bouncy webbing to play the real game. If you love the JOKER, this is your next step to discovering some vertical dimensions of a Highline.
Super soft edges and High Breaking Strength
DONKEY webbing has been dyed intensively, to achieve an excellent UV resilience result.
Its special weave with round pillowed edges and silky outlines delivers an excellent sensation for hands and feet.
Finally, the breaking strength at 32 kN is quite high for this category of webbing, but produced this way to increase its overall safety factor.
Made in France - About Quality and Safety
The DONKEY has been designed, tested and developed by Slack-Inov in France. It has been produced in collaboration with our expert athletes who we let choose its main, most important performance-based and technical characteristics, in order to offer you the perfect Trick-highline.
Every batch has been tested with appropriate machinery to check breaking strength and the fiber integrity after the production.
We truly care about your and our safety, since we are all the first users of this unique product.

Hi! Does the 50 meter longline kit come with webbing that has 2 sewn loops? Thanks! SIGMA is an element of statistical calculations, which allows to display a products’ guaranteed strength value throughout its manufacturing process. Therefore, it is related to product safety.
During the testing process, the greater the differences between the 10 recorded values, the higher turns out the sigma value.
For example, for 10 carabiners tested, their ten recorded values are usually different and not the exact same:
24,9 | 25,9 | 26,2 | 25,6 | 25,8 | 24,7 | 25,5 | 24,7 | 26,0 | 25,7 kN
So which value to take into account to display the MBS (Minimum Breaking Strength) value?
We first calculate the average:
(24,9 + 25,9 + 26,2 + 25,6 + 25,8 + 24,7 + 25,5 + 24,7 + 26,0 + 25,7) / 10 = 25,5 kN
We then calculate the variance:
24,9 - 25,5 = - 0,6 (-0,6)2 = 0,36
25,9 - 25,5 = - 0,4 ( 0,4)2 = 0,16
...and so on for the 10 measured values.
We add those 10 results:
0,36 + 0,16 + 0,49 + 0,01 + 0,09 + 0,64 + 0,064 + 0,25 + 0,04 = 2,68
And we create the average:
2,68 / 10 = 0,268
The variance is even to : 0,268
SIGMA (standard deviation) = square root of 0,268 = 0,5176
The maximum value displayed on the carabiner would be:
average of 10 carabiners = 25,5 kN
SIGMA = - 0,5176
Displayed Value = 24,0724 kN
What you should know in particular about the 3 SIGMA safety margin?
We use the 3 SIGMA method to calculate the MBS.
We multiply the SIGMA for 3 (this is why it is called “3 SIGMA”) to boost the prudency in the MBS calculation.
Taking the 10 previous carabiners as an example:
The average of those 10 carabieners is 25,5kN
3 SIGMA (3 x 0,5176) = - 1,5528
Displayed value = 23,0472 kN
