Tommy Caldwell and EDELRID: a sustainable partnership.

Together we can do more to protect nature.


Tommy is a passionate climber and environmentalist. We share both passions with Tommy and do not only develop ropes together but also like to think of (new) ways to protect our planet.

For this reason, we have decided to donate 1% of the worldwide turnover from the sale of this rope to the organization POW (Protect Our Winters).

A lot of small steps from a lot of people can have a huge impact. With the purchase of this rope you make a decisive contribution to make the earth a better planet.

 
 

What is POW?

POW helps passionate outdoor people to protect the places and lifestyles they love from climate change. Founded in 2007 by professional snowboarder Jeremy Jones, it is a community of athletes, scientists, creatives and business leaders advancing non-partisan policies that protect our world today and for future generations. The goal: Achieve carbon neutrality by 2050. You can find out more about POW here.

TOMMY CALDWELL + POW + EDELRID

Robust workhorse with PFC-free Eco Dry coating

This rope was developed in cooperation with big-wall legend Tommy Caldwell. A genuine workhorse with a particularly abrasion-resistant sheath construction. Not only is it light and easy to handle but, thanks to our PFC-free Eco Dry coating, it is also permanently water repellent and dirt resistant. The perfect rope for big walls and demanding tours.

A green and high-end work horse

As a big-wall climber, you have to be able to rely 100% on your rope. In an emergency, it is the lifesaving umbilical cord that connects you to the world away from the wall. Noone knows this better than big-wall legend and EDELRID ambassador Tommy Caldwell, with whom we developed this rope. The aim of this collaboration was to develop a rope that is not only extremely robust and abrasion resistant but also light and easy to handle. It also needed to be produced in a sustainable manner that conserves resources. After initially causing our developers major headaches, these stipulations were ultimately met to perfection in the form of the TOMMY CALDWELL ECO DRY CT 9.3 MM.

Colortec Reloaded

A braiding machine with 48 bobbins was selected to create the rope. The resultant sheath structure is particularly compact and supple. This makes the rope extremely abrasion resistant despite its small diameter.

A middle mark on a climbing rope is an important an wide spread feature for all climbers. It tells a belayer if there is enough rope left to lower the climber later. Also it helps setting up a rappel with evenly long rope ends.

The problem however, is that over time it wears out or is not very visible on a dark rope.

Our ColorTec provides a rope with a permanent middle marking, by braiding different sheath patterns on each rope half. However, in the past we could not make the difference clear enough.

 

 
 

Both we and Tommy were particularly committed to ensuring that the rope can be produced in as environmentally-friendly and resource-conserving a manner as possible. This made our Eco Dry coating the only choice for finishing the rope. The PFC-free coating does not use any perfluorinated or polyfluorinated chemicals, which are harmful to humans and the environment, and absorbs almost no water (water absorption capacity < 2%, UIAA Dry Standard). Like all our ropes, the TOMMY CALDWELL ECO DRY CT 9.3 MM is bluesign® certified.

Dry Treatment - FAQs

WHAT ARE PFC'S?
The term PFC's used in the outdoor industry refers to Perfluorinated chemicals (PFCs) a group of chemicals with over 800 substances. They were mainly developed to repel oil, grease, and water and were used in many everyday consumer products for decades, such as protective coatings in cookware (e.g. Teflon®), carpet, clothing, paper, and cardboard packaging, as well as in fire-fighting foams.

HOW DO PFC'S WORK?
PFC's are long chains of carbon-flour bonds. They are often referred to by the numbers of carbon atoms in the molecule chain (e.g. C8). The bond between Carbon and Flour is specifically strong. Therefore they have weak attraction forces between two different PFC molecules and thus a low surface tension. Water and oil on the other hand have a strong inter-molecular attraction leading to high surface friction. Liquids are repelled because the attraction force of the liquid molecules is stronger than the treated material and form a droplet.

WHAT IS THE PROBLEM WITH PFC'S?
It has been repeatedly proven that PFC's travel from the product into the environment an onwards into our water and into the human body. It also has been proven that they can pose a significant health risk for all living creatures. These substances are not readily biodegradable and the longer the chain the more stable they are.

HOW MANY MANUFACTURES OFFER PFC-FREE ROPES THAT MEET THE UIAA WATER REPELLENT STANDARD?
There are quite some brands now advertising their ropes PFC-free without having any water repellent treatment. This would be like specifically advertising an apple as "Vegan". So far there are no other brands apart from EDELRID with a PFC-free rope that also passes the UIAA water repellent standard.

THERE ARE MANY APPAREL BRANDS THAT OFFER PFC-FREE WATER REPELLENT CLOTHING: WHY ARE THERE NOT MORE MANUFACTURES THAT OFFER PFC-FREE UIAA WATER REPELLENT ROPES?
That is because dry treating a rope is much more complex then dry treating a fabric! The main differences are:

  1. SHAPE - A fabric is a plain surface that can be easily treated comprehensively – A rope is a 3-dimensional textile object with several individual elements (core yarns, sheath) and many cavities between them where water can get in and hide.
  2. DURABILITY - A dynamic rope is constantly abraised and mechanically stressed. Finding an alternative to PFC's must guarantee a similar durability which is most often not the case.
  3. SAFETY - People depend their life on a rope not a fabric. A chemical treatment can not have a negative influence on the safety characteristics of the product.

This is why alternatives are not so easy to find. They have to tick all those boxes plus pass the UIAA test. Also it has to be said, that for clothing there is no test defining a product as "water repellent" or "not water repellent".

HOW IS THE EDELRID ECO DRY TREATMENT DIFFERENT?
The Eco Dry treatment is based on a chemical substance group called paraffins and a specialized structure these branched-chain hydrocarbons are prepared. Paraffins are also more commonly known as waxes. The trick is to use these hydrophobic chemicals and set them up perpendicular to the surface that is suppose to get protected. With a nano structure like this, one makes use of the so called Lotus-effect – a simple trick of nature. The contact between water and the surface is reduced by the bumpy surface and the water therefore simply form droplets and will not be able to get in.

The challenge to solve for the manufacturer however is to get this treatment stable enough...

WHY DOES EDELRID NOT SWITCH THE WHOLE ROPE RANGE TO THE ECO DRY TREATMENT?
In order to apply our Eco Dry Treatment we had to be inventive and developed extra steps within our production processes. These processes are not fully automated yet to cover large quantities. Also changing big processes in big productions need thorough simulation and validation. For all of this to realize we will need to move step by step and need a bit more time.

HOW DOES EDELRID IMAGINE THE FUTURE OF THE RANGE REGARDING PFC'S?
We strive to have our whole Proline rope range PFC-free by 2026!
