The best Slacklines to start with are the White Line 15 or a Training 18, which guarantee simplicity for walking, thanks to the low elasticity and the width of the line (50 mm). Obviously, once you have acquired the right confidence, you can move on to more demanding lines for longer walks or spectacular evolutions such as longlines of 25mm. If, on the other hand, you feel ready to do some jumps, we recommend starting with an “elastic” Pro 20 slackline or a Trick 25.
Ciao Andrea,
SLACKIMOUFLE è necessario nel caso tu utilizzi per TRICKLINE o per LONGLINE molto tese, oltre i 10 kN.
INFINITY è comodissimo per tutte le altri situazioni. Se ci racconti che usi ne vorresti fare ti possiamo consigliare meglio.
Buona slack!

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

The product has several combination that can change the total weight. You can sum the single item weight you see in the shop, in example if you select the the 25 m K2 ROPE with NO ACCESSORY, the total weight is 3,1 kg
No, the sewn loop is not included. You can add a SEWN LOOP to this kit simply by adding to the cart the product SEWN LOOP you can find in category HIGHLINE>SEWING.

This "ratchet" is not limited in length, but in tension. It can rig up to 6kN = 600kg. We already rigged a 500m line with it for example.
Hello, FLY LINE 50 works with 2 ratchets so it does not require any SEWN END LOOP.
You can set your line lenght adjusting with the 2 ratchets.
The sewn end loop in the picture is the one of SMALL RATCHET, not of the webbing.

The HIGHRING 80 MM has meant to be used SINGLE (not tape together).
