The empty shelf above Supima.
American extra-long-staple cotton is the best fibre grown anywhere, and almost nobody has built a premium bath or intimates brand on it. The fibre premium is real but tiny at retail. The domestic capability to convert it is thinner than it looks — and thinner in towels than in lingerie.
Where this actually starts
There is no prior Supima work to continue. The memory corpus, the product board (11 families, 54 products) and the supply-research corpus (44 sources — logistics, tariffs, margins, lithium, cobalt, nickel) hold nothing textile. The design-to-market engine’s live pilot is a sonic massage hairbrush.
The sovereign index is blind here too: a supima query returns three results, none of which contain the word. Every fact below comes from open-web research, not from the estate.
Competitor landscaping cannot ride the existing index. Either this runs on external search, or the crawler is seeded with the textile and home-goods domain first. Cheap to take the first path now and the second later.
What survives of the domestic chain
“From the first bit up” means the fibre-to-finished-good ladder. Each rung either exists in the US at commercial scale or it does not. This is the constraint that decides everything downstream.
Supima ELS grown CA / AZ / NM / TX. ~400,000 bales, down 11% on the year. Licensing now free to mills, funded per-bale on the end user.
Ring-spinning operating in Georgia and North Carolina. Not a bottleneck.
1888 Mills closed its Griffin, GA terry plant April 2024 — ~50 looms, ~180 jobs, the last big one. A premium weaver remains in Georgia. Single point of failure.
Bleach, dye and finish running in South Carolina, tied to the Georgia greige supply.
Deep in Los Angeles for intimates: MOQ 25–500 per style, some at zero. Seamless knit needs 500+. Not a launch-scale constraint.
No US narrow-lace capability at quality. Calais and Caudry, Korea, or China. The one component that breaks a 100%-domestic claim on lingerie.
I first read the 1888 Mills closure as forcing a greenfield build, then corrected to “a contract call, since Authenticity50 clearly has a Georgia weaver.” Both were wrong, and the operators say so themselves.
Authenticity50, in their own 2024 and 2025 year-in-reviews: “we weren’t able to get our weaving program up and running with our manufacturers… there’s been a lot of turmoil lately in the domestic terry industry.” Two consecutive years. They are not sold out — they have nowhere to weave.
Red Land Cotton is the decisive account: “Our original towel manufacturer, 1888 Mills, closed their plant in Griffin, Georgia, in January. We quickly pivoted to American Merchant in Bristol, Virginia, only for them to close their doors in the fall of 2024… At that point, we honestly didn’t know where to turn.” They found “maybe two other mills in the United States still making terry cotton towels” — neither had capacity available, and their business models did not fit a small brand. They eventually partnered with an unnamed South Carolina facility and resumed production in summer 2025. That mill is the phone call, and it replaces the unidentified Georgia weaver as the target. (Ruled out: Fancy Terry of Inman, SC weaves jacquard only — golf, beach, throws — not plush bath terry.)
The asset nobody bought
Two domestic terry mills closed in 2024. One of them is complete, six years old, and for sale — and the seller intends to ship it overseas.
| American Merchant · Bristol, Virginia | Detail |
|---|---|
| Status | Final production run Oct 2024; touring with buyers |
| Footprint | 260,000 sq ft + 60,000 warehousing |
| Looms | 18 bath + 4 hand + 2 wash — Toyota |
| Wet processing | Reactive jet dyeing, water reclamation |
| Finishing | Automatic side-hem and end-hemming |
| Certification | OEKO-TEX Standard 100 |
| Sunk investment | > $24,000,000 |
| Staff at closure | 48 employees + 5 managers, one shift |
| Seller | Loretta Lee Ltd (Hong Kong) — Maxwell Bleakie, director |
Bleakie’s stated preference is “a buyer from India or Pakistan,” and his thesis for making it work is adding 24 more looms running imported yarn under a Made-in-USA label.
That is a commodity thesis, and it is exactly why the mill died. It does not describe a $70 Supima towel — which clears 74% gross margin at $18.15 landed, with 54% cost headroom before it reaches the category floor.
The asset is priced for a business that cannot work in America. The premium position has entirely different unit economics. Demand exists and is unserved; supply exists, sits idle, and is for sale. The gap between them is capital and an operator — which is precisely where state and federal partnership has leverage. Virginia steered 400+ jobs into that plant once, and Bristol lost them.
The towel field
Two axes matter: fibre provenance and where it is made. Almost everyone premium is imported Turkish or Egyptian. The Supima-and-domestic corner has two occupants, both small.
| Brand | Fibre | Made | GSM | Bath towel | Read |
|---|---|---|---|---|---|
| Authenticity50 | Supima pile, US base | USA | 800 | $179 / set | The direct incumbent. Seed-to-stitch story, currently sold out. |
| Onsen | Supima | unclear | waffle | — | Owns “Supima waffle.” Narrow construction niche, not plush terry. |
| Red Land Cotton | Alabama upland | USA | — | — | Farm-owned, woven in SC. Domestic story without the ELS fibre. |
| Matouk | Giza (Egypt) | import | 600–800 | $40–80 | The quality ceiling. Zero-twist, OEKO-TEX. Sets $150–300+. |
| Brooklinen | Turkish | import | 770–820 | $24–35 | The value wall. Most cotton per dollar in the category. |
| Parachute | Turkish | import | ~590 | $50–60 | soft Mid-weight at a luxury price. The exposed flank. |
| Imabari (JP) | various | import | — | — | Not a brand — a certification. The only published pass/fail quality standard in the category. |
Read the table as a gap map. Nobody is selling a plush, high-GSM, all-Supima, US-woven terry towel at scale. Authenticity50 is closest and is running out of stock rather than expanding. Onsen holds waffle, not terry. Everyone above $50 is imported.
The intimates field
The cutesy Asian segment is two distinct waves that want opposite things. Conflating them is the main way to get this wrong.
Ubras — one-size seamless, wire-free. Outsold Uniqlo to become Tmall’s No. 1 underwear brand on Singles’ Day within two years.
NEIWAI — raised $100M, 260% H1 sales growth, 70–100% CAGR over three years, 100+ owned stores in 26 cities, over 50% annual repurchase.
Data-driven sizing plus social commerce beat Victoria’s Secret on its own turf. Comfort is the product; the aesthetic is quiet, not cute.
MOEFLAVOR, Risette, Peiliee, Cuconé (Japan). All small, indie, mostly dropship or micro-batch.
The engine is TikTok — Lana Del Rey, Sabrina Carpenter and Marie Antoinette imagery, descended from Japanese Lolita and amplified by K-pop styling.
Nobody is executing it at quality. The aesthetic is downstream of costume; the materials are polyester. Real fibre in this silhouette is unoccupied.
That second panel is the opening. Cotton is native to the cutesy silhouette — ribbed bralettes, gingham, bows, soft cups — but the brands serving it compete on print, not on hand-feel. A Supima-cotton cutesy line is differentiated on the one axis the incumbents have conceded, and LA cut-and-sew can produce it at 50–300 units per style with no mill relationship.
Lace. There is no US narrow-lace source at this tier. Either the line is designed around trims that are domestically available — ribbed knits, jersey, picot edges, bows, elastic — or “Made in USA” becomes “Made in USA with imported lace.” Design around it and the claim stays clean.
The ruler nobody owns
Every US towel brand competes on GSM because it is the only number a shopper sees. GSM measures mass, not performance — a heavy towel can be slow to absorb, and a reviewer measuring Brooklinen’s published 770 got 740. There is no published, falsifiable quality standard in the American market.
Imabari has had one for years. A 1 cm² swatch is cut from every production batch and floated, unwashed, on soft water. If it does not begin to sink within five seconds, it is not an Imabari towel. Four criteria gate the mark: 100% cotton, absorbency, durability, safety — plus colourfastness, strength and dimensional stability in the lab.
Adopt a published absorbency standard, run it on every batch, print the result, and run it on competitors too. It costs almost nothing and converts an unfalsifiable “luxury” claim into a measured one — on an axis where a 590 GSM towel priced at $60 cannot follow.
Why the fibre premium is nearly free
Supima costs 30–60% more per pound than upland cotton — roughly $4.00/kg in 2025, and falling: prices slid 6.76% from November 2024 through October 2025 as ELS demand cooled. That premium sounds like a margin problem. At retail it is not, because fibre is a rounding error in a finished towel.
Two percent of retail buys the strongest fibre claim in the category and a domestic-origin story no Turkish or Egyptian competitor can answer. Against a category where median DTC gross margin is 57%, premium bedding brands hold 60%+ on DTC and 30–35% on wholesale, and healthy operators run contribution margin above 35% with LTV:CAC between 3:1 and 5:1 — the fibre is not what threatens the margin.
Domestic conversion cost, not domestic fibre. 1888 Mills closed Griffin citing rising operational costs, not raw material. Weaving and finishing is where a US-made towel loses to Turkey — which is why pricing has to sit at Matouk’s altitude ($60–90) rather than Brooklinen’s, and why the measured-quality claim in section 05 has to carry that price.
Authenticity50 has already found the cost lever: Supima in the loops, commodity American cotton in the ground weave. The pile is what you touch and what absorbs; the base is structure. All-Supima is a cleaner claim, Supima-pile is a better cost structure, and the difference is invisible in use.
Two lines, two clocks
Towels and lingerie look like one business and behave like two. The asymmetry should drive sequencing.
Gate. One mill relationship. If the Georgia weaver will not take the work, there is no second domestic call to make.
MOQ. Loom-scale — thousands of units and a real deposit.
Time to first unit. Quarters.
Moat: high. Scarce capacity is the barrier, and the same scarcity that makes entry hard makes it hard to follow.
Gate. None structural. Multiple LA shops, one vertically integrated for cotton knits under one roof.
MOQ. 25–300 per style; 500+ only for seamless knit.
Time to first unit. Weeks.
Moat: low on supply, real on taste. Anyone can make it; the aesthetic and the fibre standard are what hold.
The obvious sequence is intimates first. It de-risks nothing about towels, but it produces revenue, audience and fit data while the mill conversation runs on a slower clock. Starting both on day one is fine; starting towels alone means a long silent period gated on one phone call.
What to do next
- Confirm the Georgia weaver. Identify the mill behind Authenticity50 and establish whether it takes contract terry at emerging-brand volume, at what MOQ and lead time. Everything on the towel side is downstream of this answer.
- Open the Supima license. Fees were removed and the programme moved to per-bale funding on the end user, with digital traceability through SupimaAqre. Low cost, and the traceability is itself collateral.
- Write the quality standard before the product. Define the absorbency and durability test the brand will publish, source the lab, and run it on the competitor set first — that baseline is the launch asset.
- Sample the intimates line at three LA shops. Cotton-forward silhouettes, domestic trims only, 50 units per style. Fit and hand-feel data in weeks, not quarters.
- Seed the crawler with the textile domain. The index cannot see this category. Fixing that turns competitor tracking from a manual session into a standing instrument — pricing, GSM claims, review mining.
Which line leads, and on what capital envelope? Is “domestic” a hard constraint or a strong preference — because lace decides that for lingerie? And is there an existing entity, or is this from zero? The landscape holds either way; the build plan does not.
Measured, not estimated
Section 06 argued the fibre premium is trivial at retail. That argument is now priced through the sovereign cost engine rather than asserted. Duty inputs are the real ones: 9.1% MFN on HTS 6302.60.0020, 7.5% Section 301 (List 4A) for China, plus the 10% Section 122. Run at 5,000 units, $70 retail.
| Corridor | FOB/unit | Landed/unit | Duty burden | Gross margin |
|---|---|---|---|---|
| China | $7.00 | $9.70 | 270‰ | 86.1% |
| Turkey | $9.00 | $11.57 | 195‰ | 83.4% |
| USA | $18.00 | $18.15 | 0 | 74.0% |
| USA break-even | $27.80 | $27.95 | 0 | 60.0% |
Domestic clears the 60% premium-bedding floor with $9.80 per unit of headroom — a 54% cost-overrun cushion on the conversion estimate. Margin is not what stops these being made in America. Mill access is.
⚠The FOB figures are declared assumptions, not quotes; everything downstream of them — duty, MPF, HMF, break-even — is computed. Per-corridor FOB is the one input a real mill conversation replaces.
The jobs and security case
Priced separately, because border cost knows nothing about jobs. Modelled on the 180 jobs 1888 Mills eliminated in Griffin, Georgia, at a $52,000 wage with 40% benefits against a $230,000 median home.
| Measure | Domestic restart | Turkish import |
|---|---|---|
| Domestic content | 957‰ strong | 258‰ exposed |
| Weighted supply risk | 11 | 11 |
| Jobs | 180 | 12 |
| Annual compensation | $13.10M | $0.87M |
| Home affordability | 4× income | 4× income |
The supply risk came out identical — 11 either way. Domesticating onto a single mill buys no risk reduction: the origin advantage is exactly cancelled by the single-source flag on terry weaving. That is the post-1888-Mills situation stated numerically, and it is the strongest argument for treating the second weaver as part of the plan rather than a later problem. Reshoring onto one supplier is not de-risking.
So the trade is legible: 168 jobs and $12.2M a year in local compensation, for 9.4 margin points — with the margin still comfortably above the category floor.
