MIRUM® delivers the appearance of premium coated leather with a natural, non-plasticky hand feel and no noticeable odour. Best suited for structured bags, small leather goods, belts, and accessories with top machine stitch. Due to its thickness and stiffness, it is not recommended for garments or designs requiring significant drape, heavy pleating, or high seam tension.

Biodegradability: Fully biodegradable.
Petroleum Content: Free from petroleum-based PU and PVC.
Durability:ISO durability testing is not currently available. However, MIRUM® has demonstrated strong durability in commercial use and has been successfully adopted by multiple brands, supported by consistently positive long-term user feedback.
Water Resistance: Water-resistant.
Chemistry: Made using natural, non-toxic, petroleum-free pigments and ingredients.
Manufacturing: Produced in Illinois, USA; supplied from a warehouse in Germany.
Smell: Neutral, natural scent with no plasticky odour.
Technical Specification: Thickness 1.2 mm; backing: Lyocell jersey.
Colours / Finishes: Olive Pebbled & Cognac Pebbled.

SUBSTANZ IS THE OFFICIAL MATERIAL SUPPLIER & CONSULTANT TO MORE THAN 20 BRANDS & INSTITUTIONS
CONSULTANCY
Sustainable materials strategy for fashion brands
From material selection and sourcing to prototyping and production, we help brands make better material decisions and build more reliable supply chains.
-
We review every material in your current supply chain against origin, composition, and certification standards. You get a clear report flagging risk areas — greenwashing exposure, unverifiable claims, missing documentation — before a regulator or customer finds them first.
-
We trace your materials from raw input to finished product, documenting every supplier, processor, and transport step along the way. The result is a visual map you can hand to buyers, auditors, or your own team — no more scrambling when someone asks "where does this actually come from."
-
EU textile and packaging law is moving fast — VerpackDG, Digital Product Passport, upcoming Green Claims Directive. We assess where your current setup falls short, prioritize what needs fixing first, and help you build a compliance timeline instead of reacting to deadlines one at a time.

Frequently Asked Questions
-
Substanz connects fashion brands with verified sustainable materials and circular economy suppliers — from vegan leather alternatives to bio-based fabrics. You request materials through us, and we handle the sourcing and vetting; the manufacturing relationship stays direct between you and the supplier.
-
Browse our source materials to see what's currently available, or book a consultation if you'd rather talk through your project first. Most brands start with a short call so we can point them to the right materials from day one — no generic catalog browsing required.
-
Every material in our network is vetted for origin, composition, and circularity before it reaches a brand. We don't just list suppliers — we understand how each material performs in real production, which is where most self-sourced projects run into trouble later.
-
Both. We've worked with material R&D companies developing exhibition pieces, independent designers sourcing fabrics for a single collection, and established brands building full circular economy supply chains.
-
A first conversation covers what you're building, what materials you're considering, and where your current sourcing or compliance gaps are — from EU regulatory readiness to supply chain mapping. From there we scope what makes sense for your project.
-
This is exactly the gap we exist to close. Every material we work with goes through origin, composition, and certification review before we recommend it — the same audit process we offer as a standalone service if you want to check materials you've already sourced elsewhere.
