50-meter split of longline webbing, reduced width of 17 mm, with a maximum of 2 connection by sewing.

A brand new hybrid webbing made of UHMPE fibers (Dyneema+other brand) combined with puffed polyester lining inside the edges, to create a whole new experience in highlining.
SKY DIAMOND is thinner than normal lines, 17 mm where most standards are made of 25 mm. The 17 mm size allows to reduce significantly the drag effort due to wind. You will be amazed by the ease with which you may govern this line.
Its very soft edges, with our innovative puffed edge technology, make it still a soft and gentle experience for hands and feet.

With the help of some of the best highliners, we have combined all feedback and developed a slackline with the lowest weight and the greatest resistance possible.
SKY DIAMOND is the line for extremely long projects, where stretch of less than 3% at 10 kN makes a big difference.
The SKY DIAMOND has mass-dyed fibers to obtain even greater resistance to UV rays.
Its special texture with padded and abrasion-resistant edges will offer you a unique sensation in your hand and under your feet.
The sides are colored differently to avoid twisting during installation.
It's reduced width makes it the best in category in performing under strong wind condition.
This webbing has been invented, entirely studied and produced in France.
Each batch has been tested several times concerning its breaking load, to verify its full integrity.
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
