Balenciaga’s Spring 2026 collection applies bioengineered silk and 3D weaving to retail garments, reflecting broader shifts in material innovation and sustainability across luxury fashion.
Balenciaga’s Spring 2026 ready-to-wear collection includes two garments made with a material that has, until now, remained outside the commercial fashion system. A white collared shirt and a black shirtdress are produced using bioengineered silk protein yarns developed by German biotech company AMSilk, marking the first time the material has been used in retail fashion products sold by a luxury house. The pieces are available in select Balenciaga stores and online.
The silk alternative is created using fermentation rather than silkworms. AMSilk produces silk proteins inspired by spider silk, then spins them into yarns designed to behave like conventional silk in wear and appearance, with added elasticity and resistance to creasing. According to the company, the yarns are microplastic-free, fully biodegradable, and vegan, with approval from The Vegan Society and skin-safety testing conducted by the Hohenstein Textile Testing Institute.
AMSilk says the production process requires 97 percent less water and generates 81 percent fewer carbon dioxide emissions than traditional silk manufacturing, while avoiding animal agriculture and fossil-based inputs. To support commercial supply, the company has expanded its partnership with Evonik, establishing a dedicated manufacturing line at Evonik’s biotechnology facility in Slovakia.
According to AMSilk Chief Executive Officer Ulrich Scherbel, the Balenciaga garments represent a shift from demonstration to deployment. “Seeing our material reach consumers through a global luxury brand is a defining moment for AMSilk. This application shows that bioengineered materials are no longer experimental. They are ready for demanding industrial environments and real market adoption. It reflects years of technological progress and demonstrates how innovation at material level can enable both performance and more resilient production systems,” Scherbel said in a statement.
3D weaving
The Spring 2026 collection also includes tailored garments produced using 3D weaving, a method that forms structure directly on the loom rather than through cutting and assembly after the fact. Developed with textile technology company Weffan, the process integrates elements such as seams, pockets, and sleeves into the fabric during weaving, reducing material waste and streamlining production.
Balenciaga applied the technique to jackets and trousers, allowing the garments to emerge from the loom with much of their shape already established. Parent company Kering has described the approach as compatible with existing industrial systems, addressing one of the main barriers that has historically kept advanced textile techniques from wider adoption.
The result, Kering says, is a “reimagined approach” to suiting, one that’s marked by distinctive 3D-woven seams, integrated pockets, and sleeves. “Beyond aesthetics, the process significantly reduces offcut waste and manufacturing time, while addressing inefficiencies and unnecessary material use at the earliest creative stages,” the house says. Balenciaga positions the Weffan collaboration as future-proof alternative for tailoring within the fashion industry.
By embedding structure during weaving, the method limits offcuts and reduces the number of production steps required to complete a finished garment. Kering has positioned the process as part of its broader efforts to reduce waste across design and manufacturing without altering the visual language of the product.
Balenciaga’s sustainability commitments
Balenciaga’s use of bioengineered silk and woven-in structure aligns with sustainability commitments the house has articulated over recent years.
Material choices remain one of fashion’s largest environmental pressure points. According to data from the Ellen MacArthur Foundation, the fashion industry produces more than 130 million tonnes of fibers annually, with synthetic fibers accounting for more than 60 percent of global production. Textile production is responsible for approximately ten percent of global carbon emissions and consumes tens of trillions of liters of water each year.
Balenciaga’s Spring 2026 materials follow earlier experiments by the house with alternative inputs. In 2022, Balenciaga introduced a mycelium-based leather alternative developed in collaboration with Italian startup Sqim. The material was grown from mushroom mycelium rather than derived from animal hides, reflecting the brand’s interest in bio-based substitutes for conventional luxury materials. The project positioned Balenciaga among the first major luxury houses to test mycelium materials in finished products rather than prototypes, reinforcing a pattern of treating new materials as part of product development rather than conceptual showcases.
The brand also incorporated Bananatex, a fiber made from abacá banana plants, into select accessories, including versions of its Triple S sneaker and bags. Developed by Swiss company Bananatex and produced without chemical fertilizers, pesticides, or irrigation, the material reflected Balenciaga’s interest in plant-based fibers with established durability rather than recycled synthetics alone.
Efforts have also included the elimination of fur and exotic leathers, increased use of recycled and upcycled fibers, and the launch of a resale program designed to extend product life. Balenciaga has also committed to aligning 100 percent of its materials and manufacturing processes with Kering’s environmental standards, which address chemical management, biodiversity impact, and emissions accounting.
