Elevate™ Signature Pebble
from €15.00

Elevate™ Signature Pebble is a bio-based leather alternative developed by Uncaged Innovations. It features a soft, premium grained leather appearance with a natural, non-plasticky hand feel.

Designed for structured, flat and top-stitched designs, Signature Pebble is particularly suited to bags, accessories and other fashion applications requiring low stretch and minimal drape.

Material & Composition

  • 95% bio-based plant content / 5% mineral content: made from non-food agricultural grain by-products, creating a circular use for agricultural resources without competing with the food chain. USDA Certified BioPreferred®

  • Natural, non-toxic, petroleum-free pigments and chemistry

  • No petroleum-based PU or PVC

Biodegradability

A third-party Life Cycle Assessment (LCA) reports 33% biodegradation within the first six months under the tested conditions. The material contains less than 1% bio-based PU coating, which does not prevent overall biodegradation. Third-party documentation is available upon request.

Performance

Developed to meet key ISO performance standards for fashion applications. Its solid grain-protein core accounts for approximately 85–90% of the material, avoiding the conventional surface film used in laminated synthetic leathers and helping prevent peeling over time.

Technical Specifications

  • Thickness: 0.9–1.1 mm

  • Backing: 100% GOTS-certified organic cotton interlock

  • Stretch: Low

  • Finish: Signature Pebble

  • Water resistance: ISO Water Spotting Grade 5 — 16 hours without bubbling or halo formation.

  • Engraving: Suitable for laser engraving

  • Embossing / stamping: Not recommended

  • Manufacturing: New York State, USA

  • Current batch: Amber wood fragrance

Applications

Signature Pebble is suitable for structured bags, accessories, flat constructions, top machine-stitch designs and other applications requiring a stable material with minimal drape.

The growing field of biomaterials and sustainable materials is creating new possibilities for fashion. Elevate™ Signature Pebble offers a bio-based leather alternative, supporting the development of circular economy solutions for garments and accessories.
