Material Standards

TENDLER prioritizes responsibly sourced materials selected for their quality, longevity, and reduced environmental impact. All fabrics, yarns, and leathers are sourced from Italy.

Knitwear is developed using yarns composed of 95% recycled cashmere and 5% recycled wool, while denim utilizes fabric woven from 100% recycled and certified regenerative cotton. Leathers are sourced from renowned tanneries recognized for their craftsmanship and quality. 

Materials are certified to internationally recognized standards including GRS, ReVerSo, RWS, GOTS, and certified regenerative standards, supporting recycled content, traceability, regenerative agriculture, animal welfare, and responsible sourcing practices throughout the supply chain.

TENDLER views these considerations not as separate from its luxury standards, but as part of the broader pursuit of creating products with integrity and lasting quality.

Measured Impact

TENDLER materials are evaluated through certified sourcing systems and lifecycle analysis, measuring reductions in water use, energy consumption, emissions, and other environmental indicators when compared with conventional materials.

Material Index

Recycled Cashmere

Recycled cashmere begins with the preservation of a fiber too delicate and too rare to be lost. Fine cashmere remnants and loose fibers are carefully gathered; what might otherwise disappear from the cycle of making is treated with the attention it deserves: collected, protected, and prepared for renewal.

Once gathered, the fibers are gently opened and sorted by hand, separating what can be returned to its purest use. The work requires patience — loosening the fiber without diminishing its softness, preparing it without stripping away the natural warmth that gives cashmere its quiet depth.

From there, the cashmere is spun again into yarn, carrying its original tenderness into a new form. The yarn is then knitted slowly into fabric, where density, gauge, and tension determine the final hand: soft but substantial, warm without weight, intimate against the skin. Reviewed through each stage of making, the material becomes a garment defined by preservation — a precious fiber gathered carefully, renewed with discipline, and allowed to continue its life in another form.

Recycled Denim

Recycled denim begins within the making process itself, where fresh cuttings and loose fibers are reclaimed and gathered at their source, while the material is still pure and full of purpose. Nothing precious is treated as incidental; each remnant is preserved for the possibility of becoming cloth again.

Once collected, the cotton is opened back into fiber and prepared for spinning. It is sorted, cleaned, carded, and blended with care, so the material can regain the cohesion denim requires. The work is one of calibration: fiber length, yarn strength, surface texture, and the dry, substantial hand that allows denim to feel structured without becoming stiff.

From there, the cotton is spun into yarn and woven through warp and weft into denim. The twill gives the cloth its diagonal grain; the tension of the weave gives it structure; the finishing gives it depth, touch, and movement. Carried through cutting, sewing, washing, and review, the fabric becomes a garment made to hold its shape, soften at the seams, and gather the marks of wear slowly over time.

Organic Cotton

Organic cotton begins in the soil, where the seed is cultivated without synthetic pesticides or genetic modification. It asks more of the field before it ever becomes fiber: cleaner ground, slower tending, and a closer relationship between the crop and the hands that raise it. Its character is shaped first by the quality of the ground and the patience of the harvest.

Once gathered, the cotton is opened from the boll and separated into its finest fibers. The work is patient and deliberate — cleaning, combing, and aligning the fiber so that its natural softness is preserved from plant to thread. Each passage depends on precision: the handling of the fiber, the care of its preparation, and the quiet discipline required to keep a natural material intact as it begins to change form.

From there, the fiber is spun into yarn, drawn into fabric, and carried through a chain of making watched and reviewed at every stage. For cotton to be GOTS-certified, care must continue beyond cultivation, following the material through processing, manufacturing, and labeling, with environmental and social criteria applied throughout the textile supply chain.

Certifications

TENDLER materials are supported by internationally recognized standards verifying recycled content, organic fibers, regenerative sourcing, animal welfare, chemical safety, and supply chain traceability.
