The Journey of Our Wool: From California Ranches to San Francisco Sewing

When you slip on a Herderin wool piece, you're wearing a story that begins in Northern California's grasslands and ends in a San Francisco sewing studio—a closed loop of regenerative practice and local craftsmanship that we believe represents the future of fashion in the Bay Area.

Why Wool? Why Now?

As a Bay Area wool brand, we're often asked why we've centered our material strategy around fiber from grazing animals when so many sustainable brands are moving toward plant-based alternatives. The answer lies in understanding regenerative agriculture—and recognizing that well-managed grazing can actually heal degraded land.

The wool in our AW26 collection comes from two distinct sources, each chosen for its regenerative impact: Climate Beneficial™ certified wool from Northern California ranches, and Nativa™ merino wool from US ranchers committed to animal welfare and land stewardship. Both represent a radical departure from conventional wool production, which too often prioritizes volume over ecosystem health.

Northern California's Climate Beneficial Wool

Our Climate Beneficial wool comes from Northern California sheep ranches where grazing is managed to build soil carbon, increase biodiversity, and restore watershed function. These aren't industrial operations—they're multi-generational family ranches working with organizations like Fibershed to prove that wool production can be a climate solution rather than a climate problem.

Climate Beneficial certification means that soil samples are taken annually to verify that carbon is being sequestered in the ground beneath the sheep's hooves. The ranchers we work with practice adaptive multi-paddock grazing—moving sheep frequently to mimic the patterns of wild herbivores. This allows grasslands to rest and recover between grazings, deepening root systems and pulling atmospheric carbon into the soil.

The result? Wool that has a negative carbon footprint. Unlike synthetic fibers derived from petroleum, or even some plant fibers grown with intensive inputs, this wool actively removes carbon from the atmosphere while it's being produced.

For us, this isn't just an environmental calculation—it's a recognition that materials carry meaning. When you understand that your sweater is connected to restored soil, cleaner water, and thriving bird populations in Northern California grasslands, you wear it differently. You care for it differently.

Nativa Merino: US-Sourced, Animal Welfare Certified

Our merino wool comes from Nativa-certified US ranches, primarily in the Mountain West and Northern Plains. Nativa certification guarantees animal welfare standards that go beyond industry norms: no mulesing (a painful practice common in Australian wool production), verification of humane handling, and independent audits of ranch conditions.

We specifically sought US-sourced merino because we wanted to support American ranchers and reduce the carbon emissions associated with importing wool from Australia or New Zealand. Yes, those countries produce excellent wool—but why ship fiber halfway around the world when we have skilled ranchers here?

The Nativa ranchers we work with are managing for ecological outcomes similar to our Climate Beneficial partners: building soil health, maintaining wildlife habitat, and stewarding watersheds. Many are third- or fourth-generation ranchers who've watched their land degrade under conventional practices and are now actively working to restore it.

What makes Nativa merino different from standard merino? The fiber quality is identical—that same incredible softness and temperature regulation that makes merino the gold standard for base layers and next-to-skin pieces. But the production system ensures the sheep producing it are treated with dignity, and the land they graze supports biodiversity rather than monoculture.

From Ranch to San Francisco: The Manufacturing Story

Once the wool leaves these ranches, it's processed at US mills that can handle small-lot production while maintaining fiber integrity. We work with mills that understand the value of traceability—they know which ranch the wool came from, and they can tell us exactly what treatments (or lack thereof) each lot received.

From the mill, greige goods arrive at our dyeing partners. We use three dye processes for our wool pieces:

Botanical Colors plant-based dyes derived from roots, leaves, and food waste. These natural dyes create the subtle, earthy colorways that define our aesthetic—colors that look like they came from the land because they did.

OurCarbon organic waste dyes, which transform food and agricultural waste into permanent, beautiful color. Coffee grounds, avocado pits, onion skins—materials that would otherwise decompose or end up in landfill instead become the rich browns, terracottas, and greens of our collection.

OEKO-Tex certified non-toxic synthetic dyes for colors that can't be achieved through natural dyeing. We're transparent about this—some shades require synthetic chemistry, and when we use it, we ensure it meets the strictest safety standards for both garment workers and end users.

After dyeing, fabric arrives at our San Francisco sewing studio. This is where pattern engineering for tall bodies meets the skilled hands of local sewers who've been working in the Bay Area garment industry for decades. They know fabric—how wool drapes differently than cotton, how to handle the stretch in a merino jersey, how to finish a seam so it lies flat against a torso that's longer than industry-standard patterns account for.

San Francisco manufacturing isn't just about supporting local economy (though that matters). It's about control. When we cut and sew in the same city where we're based, we can ensure the proportions are right. We can adjust patterns based on wear-testing feedback. We can guarantee that the people sewing our garments are paid fairly, work in safe conditions, and have agency in their work.

What This Means for You

When you buy a Herderin wool piece, you're buying a garment with a known biography. You can trace it from specific Northern California grasslands or Western ranches, through US mills, through Bay Area dye houses, to San Francisco sewing studios. Every hand that touched it was paid fairly. Every step in the process prioritized ecological regeneration.

This is what we mean when we say we're a Bay Area wool brand—not just because we're located here, but because we're embedded in the regional textile ecosystem that Fibershed has been building for over a decade. We're part of a network of ranchers, mills, dyers, and makers who believe fashion can be a force for land restoration rather than extraction.

For tall women who've spent years settling for garments that don't fit, knowing where your clothes come from—and that they were made with intention from soil to skin—changes the relationship you have with getting dressed. It's no longer just about covering your body. It's about participating in a system that values both you and the land.

The Future of Regional Wool

We're still a small brand, and our impact is still small. But we're building toward something larger: a viable model for regional textile production that keeps fiber, fabric, and finishing within a few hundred miles of where the final garment is worn.

California produces wool. California has mills. California has skilled dyers and sewers. The infrastructure for a closed-loop system exists—it just needs brands willing to commit to it, even when it would be cheaper and easier to source globally.

As we grow, we're committed to increasing the percentage of our wool that comes from California ranches specifically. We want to prove that it's possible to build a Bay Area wool brand that sources, produces, and sells within the same bioregion.

Because at the end of the day, this is about more than making clothes that fit tall bodies (though that matters enormously). It's about demonstrating that fashion can be rooted in place, accountable to people, and regenerative for land.

The wool you wear can tell a story of restoration. And that story begins here, in Northern California's grasslands, under the feet of sheep whose grazing is healing the earth.
