Kering Material Innovation Lab Presents S|STYLE 2025 – Denim Lab
In September 2025, Milan Fashion Week hosted a landmark event in the realm of sustainable fashion: the Kering Material Innovation Lab (MIL) unveiled S|STYLE 2025 – Denim Lab. This initiative brings together a curated selection of emerging fashion brands globally to explore sustainable innovation, with a special emphasis on the future of sustainable denim and the critical issue of water use in the textile industry.

Launched in 2020, S|STYLE Sustainable Style has evolved as a vital platform for responsible fashion. This year’s special edition, SISTYLE – DENIM LAB, is an ambitious project conceived by Giorgia Cantarini. Aimed at engaging young international brands, the lab showcases a unique denim look created utilizing fabrics developed through advanced, sustainable processes, simultaneously showcasing the potential for reduced usage of natural resources. The creative looks designed for this event received technical support and innovative materials from Kering’s MIL, a dedicated hub for sustainable textile innovation.
The theme this year pivots around water, marking it as the most essential resource for the textile industry—particularly denim. This focal point directly aligns with Kering’s newly unveiled Water Strategy, which aspires to achieve a Net Water-Positive impact by 2050. Traditional denim production is notoriously water-intensive; producing a single pair of jeans can require thousands of liters of water due to the processes of cotton cultivation, dyeing, and finishing. Consequently, denim was chosen as the material of focus for this project, serving as both an iconic textile and a symbol of environmental impact and water consumption.





Designers participating in S|STYLE – DENIM LAB faced the challenge to creatively reinterpret denim through a conscious and experimental approach. They employed advanced technologies for dyeing, washing, and finishing that drastically reduce water usage, minimize or eliminate harmful chemicals, and utilize cotton sourced from regenerative farming practices—marking a cutting-edge approach to sustainable natural materials.
Thanks to Kering’s MIL, designers had access to next-generation denim fabrics, developed through advanced sustainable materials and processes:
– Smart Indigo® by Sedo Engineering: This electrochemical dyeing process employs water, electricity, and pure indigo pigment to drastically reduce and recover polluting chemicals. Used by Institution, Gerrit Jacob, Gisele Ntsama, and Macy Grimshaw, this innovative technique highlights the potential for reducing the environmental impact of dyeing.
– D(y)enim® by Sonovia: Utilizing ultrasonic and cavitational dyeing technology, this material reduces water usage by 85%, eliminates harmful chemical products, and cuts CO2 emissions by 79%, while lowering energy consumption by 60%. Designers Jeanne Friot, Nadya Dzyak, Phan Dang Hoang, and Sia Arnika incorporated this revolutionary fabric into their collections.
– Tonello Srl Technologies
– Laser 2.0: This technology eliminates harmful chemicals while enhancing precision and operator safety, speeding up production processes. Used by Gerrit Jacob, Macy Grimshaw, Phan Dang Hoang, Sia Arnika, and Institution, it is a transformative approach to denim finishing.
– EGO: Utilizing ozone as an oxidizing agent for decolorizing indigo, this method conserves both water and chemicals. This technique featured prominently in collections from Gerrit Jacob, Jeanne Friot, Nadya Dzyak, Phan Dang Hoang, Sia Arnika, and Institution.
– NoStone®: By replacing pumice stones with an innovative abrasive coating, this technology mitigates the environmental impact associated with stone extraction and disposal. It was utilized by Jeanne Friot, Nadya Dzyak, and Sia Arnika.
– UP: This system promotes the continuous recycling of wash water, achieving a reduction in water and energy consumption of up to 53%. This technology was embraced by all participating designers.
– Wake: A sustainable dyeing technique utilizing local plants and vegetable waste without harmful chemical additives was featured in the works of Nadya Dzyak and Phan Dang Hoang.
– Tonello Dryers: High-efficiency dryers designed to ensure rapid, uniform drying with lower energy consumption were employed by all designers in the exhibition.
– Regenerative Cotton: Used by all emerging brands, this cotton comes from the Kering
Regenerative Fund for Nature, launched in 2021 in partnership with Conservation International. The initiative promotes farming practices aimed at increasing soil carbon capture, restoring habitats, conserving water, and improving farmers’ livelihoods by eliminating synthetic chemicals.
– Post-consumer recycled cotton fused with regenerative cotton for high-quality fabrics was incorporated by Institution, Gerrit Jacob, Gisele Ntsama, and Macy Grimshaw to enhance their designs while adhering to sustainable practices.

Taking place at the iconic Fondazione Sozzani —a venue synonymous with cultural innovation and circular fashion—the opening of S|STYLE – DENIM LAB was slated for September 26, followed by public access on September 27 and 28.
The exhibition space hosted a site-specific installation by Italian-Argentinian artist Mariano Franzetti, designed to enhance the designers’ creations and transform the exhibition into a fully immersive artistic experience. He used recycled and regenerative denim fabrics provided by Berto, further showcasing how sustainability can harmoniously coexist with creativity.
