We have developed ropes with zero sheath slippage, a low impact force and a water repellent surface without the use of PFC. In practice it means that our new ropes from Ocún will enable you to climb to the maximum, will gently catch all falls and will long be resistant to visible wear. Moreover, all of the ropes from the new line are equipped with special safety features and, as a bonus, we have added rope markers to them to indicate the centre of the rope.

The new line of Ocún ropes brings four different models. They differ from each other by their diameter and related parameters. Together, they are the strict production controls and our emphasis on maintaining the highest quality standards for each individual rope. Vision 9.1, Spirit 9.5, Cult 9.8 and Guru 10 are our responses to the most common requirements that climbers have. We are sure that every climber will be able to choose just the right one from these four. All of the ropes are available in various lengths and colours.

To make our ropes truly exceptional in terms of handling, durability and reliability we have applied some sophisticated and not yet common methods for yarn processing, weaving and finishing the ropes. It´s important for us to share their explanation with you, so that you can be completely confident when climbing with OCÚN ropes, believe your gear with not the slightest doubt and fully focus on your send and nothing else in the world.

OCÚN Climbing Lab

Here is the methodology of OCÚN Climbing Lab developed for manufacturing our ropes:


Individual strands of the core are heat treated to give the rope its dynamic and mechanical properties.

The individual strands of the core are chemically and thermally treated before weaving. This improves the interaction of core strands and its mechanical and dynamic properties.


Final heat treatment of the braid ensures compact flexibility and supple handling.

The final thermal treatment is a standard treatment applied to all Ocún ropes to ensure compact flexibility and pleasant handling properties.


Every Ocún rope has a colored band marking the mid-point to make descending easier.

Each Ocún rope has a colored band 8 cm long to mark the midpoint. The color used does not have a harmful effect on the braid materials nor does it change the mechanical properties of the rope. Each new rope comes with a marker that can be used to brighten the midpoint mark or mark a new midpoint if the rope is shortened by the user.


Woven fibers give permanent protection and create a barrier against moisture and impurities.

Each of our ropes has a permanent PFC-Free protective layer that creates a barrier to prevent water and impurities from reaching the core. This protective treatment of fibers also reduces their friction and increases the mechanical resilience of the weave. As a result, the life span of the entire rope is extended.


Strict control of fiber tension during the manufacturing process ensures perfectly balanced tension throughout the entire cross-section of the rope.

Ocún devotes exceptional attention to checking fiber tension when processing and weaving strands. This technological discipline ensures that Ocún ropes perfectly balance tension throughout the entire cross-section, enabling the rope to attain excellent results when measuring normative parameters.


Every Ocún rope is color coded on one end to indicate length and increase safety during use.

Ocún ropes have visible length markings. One end of the rope is always marked with the color of the particular length (50m/yellow, 60m/blue, 70m/green, 80m/purple). This standard marking of rope length helps increase safety when tying in and descending, where knowledge of rope length is important. If a user needs to shorten a rope, each rope comes with a gray replacement label and blank area to mark the individual length.


The ends of all ropes have diferent color codes to easily distinguish them from one another and ensure uniform use.

Both ends of the rope are fitted with a durable, multi-layer label with required information (manufacturer, standard, certification, year of manufacture, type, model, diameter and length) and a hidden serial number to trace the origins of the rope. Each end has a diferent color making them easier to identify, that way you can alternate the active end of the rope to ensure even wear of both.


Allows accurate supervision over the manufacturing process and quality of every individual rope. Unique number is shown on the end caps, packaging and the diary of every rope.


Does not contain fluorocarbons C8 which are toxic and nondegradable in nature.

We have been collecting experiences and knowledge for developing our very own dynamic ropes for almost two decades. Our experts are well versed in both climbing and textile engineering. Our greatest advantage is that both of these disciplines enjoy traditions that reach back over a hundred years in the lands of former Czechoslovakia. We draw upon the industrial base and manufacturing experience.
