At the centre of the film is professional freeskier, climber and highliner Coline Ballet-Baz, whose experience in extreme mountain environments highlights an important reality: durable products matter.
For athletes spending long days exposed to snow, rain, wind and abrasion, performance is not theoretical. What they wear must function reliably over time, often for years of repeated use in demanding conditions.
This is where TESTEX CIRCULARITY comes in.
The film follows Coline’s journey from the mountains to the TESTEX Technology Laboratory in Zurich, where physical textile testing helps make durability measurable. Together with ARC’TERYX, TESTEX highlights how independent testing and verification can support more durable and circular textiles through scientifically grounded product evaluation.
Measuring textile durability through physical testing
Within TESTEX CIRCULARITY, durability is evaluated through structured laboratory testing designed to assess how products perform under repeated stress and use.
Stretching, washing and abrasion testing help determine how materials withstand real-life conditions over time. These assessments form an essential part of the TESTEX CIRCULARITY framework, alongside repairability and recyclability.
As shown in the film, durability is not only relevant for product longevity. It is also fundamental to circularity. Products that fail prematurely cannot realistically support circular systems.
Why independent textile verification matters for circularity
The documentary also highlights the role of independent verification in the textile industry.
As expectations around sustainability and circularity continue to increase, brands are increasingly required to substantiate product claims with measurable data and credible assessment methods.

TESTEX CIRCULARITY helps brands in the textile industry evaluate durability, repairability and recyclability through independent laboratory testing and evidence-based circularity assessment.
By combining laboratory expertise with circular product evaluation, the framework supports more transparent and measurable approaches to circularity.

Advancing measurable circularity in the textile industry
For us, this reflects the growing international relevance of measurable circularity and the increasing importance of scientifically verified product performance within the textile industry.
This collaboration is more than a film. It is an opportunity to contribute to a broader conversation about durability, product longevity and the future of circular textiles.
