About Harvest & Mill

Harvest & Mill is partly sustainable on materials: our scan of all 135 styles found 72.7% plant fibre (27.3% synthetic, 0% animal). Documented facts: 100% U.S.-grown organic cotton; all spinning, knitting, finishing and sewing done in the USA (Bay Area sewing within ~15-20 miles of the Berkeley studio); PETA-approved product line; Fibershed membership; use of plant-based/low-impact dyes; compostable/recyclable packaging; and carbon accounting via Green Story with Gold Standard/CDM/Climate Action Reserve-verified offsets. These
Harvest & Mill garments are made entirely in the USA “from seed to stitch”: organic cotton is grown on U.S. organic cotton farms, then spun, knit and finished at American (“heritage”) mills in the USA, and all sewing is done in independent, family-owned factories in Oakland, Berkeley, San Francisco and Emeryville, all within roughly 15 to 20 miles of the brand’s Berkeley studio. Low-impact black is dyed with fiber-reactive dyes in the USA and natural-dye pieces are colored by dye artists/farmers in Indiana and California. This all-domestic supply chain is stated on the brand’s own site and corroborated by Fibershed and independent press.
Harvest & Mill is an independent organic cotton clothing company founded in 2012 in Berkeley, California by Natalie Patricia, who began by sewing custom clothing one piece at a time before building it into an American “seed to stitch” apparel brand. No parent company or corporate owner is documented; independent journalism (Berkeleyside) and Crunchbase both list Natalie Patricia as founder. One source (Berkeleyside/CommonShare) also references Paul Wallace in connection with the brand’s early organizing, so a co-founder role for Wallace is mentioned in secondary sources but Natalie Patricia is the consistently attributed founder/owner. The brand remains privately held and independent as of 2026.
Harvest & Mill is a real, currently-trading legitimate business as of July 2026: its website (harvestandmill.com) is live and fully operational for e-commerce, carries a “© 2026 Harvest & Mill” notice, has working product pages and cart, and the brand has publicly stated plans to release new natural-dye collections in 2026 (with Botanical Colors). It is listed by Fibershed, Bay Area Made, and multiple independent ethical-fashion directories, and has been covered by independent press (Berkeleyside). This is the Berkeley, California organic-cotton clothing brand, not a similarly named business in another industry (e.g. mattresses).
Harvest & Mill is a slow-fashion, small-batch brand, not fast fashion: it produces a limited line of organic cotton basics and loungewear (tees, sweatpants, shorts, joggers, socks) sewn in small local Bay Area factories, emphasizes zero-waste and limited domestic runs, and operates on a “seed to stitch” model rather than high-volume seasonal turnover. Its scale, U.S.-only supply chain, and made-to-limited-quantity approach are the opposite of the fast-fashion model.
Harvest & Mill is largely non-toxic: 72.7% of its range is plant fibre that breathes and biodegrades, with 27.3% plastic-based synthetics that can shed microplastics. Certifications: Harvest & Mill states on its own pages that its “entire product line is PETA-approved” and that it is a member of Fibershed (a nonprofit for regional fiber systems); it also reports carbon footprints via Green Story using Life Cycle Assessment methodology with offsets verified by Gold Standard, the UN Clean Development Mechanism, and the Climate Action Reserve. GOTS (Global Organic Textile Standard) certification is widely stated by third-party retailers and blogs (e.g. Q for Quinn, ethical-clothing.com) but is NOT documented on Harvest & Mill’s own certification/sustainability pages, so it should be treated as an unverified third-party claim rather than a brand-confirmed certification. No OEKO-TEX, Fair Trade, B Corp, or European Flax certifications were found for Harvest & Mill..
Harvest & Mill holds these certifications: Harvest & Mill states on its own pages that its “entire product line is PETA-approved” and that it is a member of Fibershed (a nonprofit for regional fiber systems); it also reports carbon footprints via Green Story using Life Cycle Assessment methodology with offsets verified by Gold Standard, the UN Clean Development Mechanism, and the Climate Action Reserve. Our scan of 80 Harvest & Mill styles found 100.0% is 100% plant fibre, the measurable fact behind Harvest & Mill’s claims.
Our scan of all 135 Harvest & Mill styles found 72.7% of the range is 100% plant fibre, with 0% animal fibre, 27.3% synthetic and 0% semi-synthetic. That composition is the measurable fact behind what Harvest & Mill is made of, so check the specific Harvest & Mill label for any individual piece.
How we scan. Every figure on this page comes from the Throne Standard scan: we read the fibre composition off each live product on the brand’s own site, style by style, and count only single-fibre plant cloth (cotton, linen, hemp) as natural. Animal fibres such as wool, silk and cashmere and plastic-based synthetics such as polyester, nylon and elastane sit outside the plant-fibre figure, and regenerated fibres such as viscose, bamboo, modal and Tencel are counted as semi-synthetic. Percentages are calculated over the styles that state a composition; anything unlabelled is shown separately.
