Mushroom Leather and the Future of Bags
Hermès, Stella McCartney, and Adidas have all released mushroom-leather products. Here's what mycelium leather actually is, how it performs, and what it signals for the next decade of luxury bags.

Hermès released a mushroom-leather bag. Stella McCartney built a luxury sustainable label around it. Adidas tested it in sneakers. Here's what mycelium leather actually is and why luxury houses are betting on it.
What mushroom leather actually is
Mushroom leather is a bio-based material made from mycelium — the root network of mushrooms. Mycelium is grown on a substrate (often agricultural waste) in controlled conditions over 1 to 3 weeks, then harvested as sheets, tanned, and finished into a material that looks, feels, and performs like animal leather. Two leading companies dominate the category. Bolt Threads makes Mylo, used by Stella McCartney, Adidas, and Lululemon. MycoWorks makes Reishi, used by Hermès for the Victoria handbag and Ligne Roset for furniture. Both processes are patented; both produce materials that approach the hand-feel and performance of mid-grade animal leather.
- 01
Source: mycelium (mushroom root structure), grown on agricultural waste substrate.
- 02
Production time: 1 to 3 weeks from inoculation to harvest.
- 03
Tanning: low-impact, no chrome required, often using bio-based tanning agents.
- 04
Finishing: can be embossed, dyed, and treated to mimic various leather types.

Why luxury houses are investing
When Hermès released the Victoria bag in Reishi leather in 2021, the fashion industry took notice. Hermès is the brand most associated with traditional leather quality — when they release a mushroom-leather product, it signals that bio-leather has crossed the credibility threshold for luxury applications. The luxury investment thesis is straightforward. Animal leather has serious environmental and ethical problems that aren't going away. Younger luxury buyers (the under-35 demographic that drives most growth) increasingly value sustainable practices and are willing to pay for them. Mushroom leather solves the ethical concerns without compromising quality at the luxury tier — making it the most credible alternative for high-end brands.

How mushroom leather actually performs
Performance is where mushroom leather has surprised skeptics. Independent testing and multi-year owner reports suggest the material is comparable to mid-grade animal leather across most metrics: tear strength, abrasion resistance, water resistance with finishing, and aging characteristics. Premium animal leather (full-grain calfskin) still outperforms on multi-decade durability, but the gap is smaller than initial assumptions suggested. The key advantage beyond ethics: mushroom leather can be tuned during growth. Producers can adjust density, thickness, and surface texture by controlling growing conditions. This gives designers more flexibility than working with the natural variability of animal hides.
- 01
Tear strength: comparable to mid-grade calfskin.
- 02
Abrasion resistance: 80 to 95% of comparable animal leather.
- 03
Aging: develops a soft patina with use, though less dramatically than traditional leather.
- 04
Water resistance: requires finishing (same as animal leather); finished products handle light rain well.
- 05
Customization: thickness, density, and texture can be tuned during growth.
Price and accessibility today
The honest assessment: mushroom leather is currently concentrated at the luxury tier because production scale is still small. A Hermès Victoria bag in Reishi costs roughly the same as the calfskin equivalent (low five figures). A Stella McCartney Mylo Falabella costs $1,500 to $2,500. Mid-range and mass-market mushroom-leather products exist but are limited. This will change. Bolt Threads and MycoWorks have both scaled production significantly through 2025 and 2026. Industry estimates suggest mushroom leather prices will fall 50 to 70% as production reaches industrial scale, bringing the material into mid-range bags and accessories within the next 3 to 5 years.
What to expect in the next 5 years
Mushroom leather is poised for significant expansion through 2030. Three trends will drive the category: production scale increasing prices to fall, mainstream brands beyond luxury adopting the material, and consumer acceptance crossing the credibility threshold as more people own bio-leather products and report positive experiences.
- 01
By 2028: mid-range bags and accessories (Coach, Polène, Cuyana) likely to release mushroom-leather lines.
- 02
By 2030: mass-market products (Madewell, Everlane) likely to include mushroom-leather in basics.
- 03
Luxury innovation continues: expect more Hermès collaborations and Stella McCartney expansion.
- 04
Competing bio-leathers (cactus, pineapple, apple) will continue to grow alongside mushroom leather, not be replaced by it.

Questions, answered.
Is mushroom leather worth the luxury price?
If you'd otherwise buy luxury leather and care about the ethical and environmental dimensions, yes. The materials perform comparably to mid-grade animal leather at the luxury tier. For shoppers who prioritize price, more affordable bio-leathers (cactus, pineapple) make better entry points.
Will mushroom leather replace animal leather?
Probably not entirely, but it will replace meaningful market share — especially in mid-range and mass-market categories. The highest-end luxury segment will likely continue using traditional leather for the foreseeable future.
How long does mushroom leather last?
Quality mushroom leather products from premium brands are expected to last 5 to 10 years with normal care, similar to mid-grade animal leather. Long-term durability data beyond 10 years isn't yet available since the material is too new. Early signs are positive.
