Activewear Manufacturer for $20M to $500M Brands
What to demand from a manufacturing partner at your size, and how we run production for brands that have outgrown their first factory.
Ohzehn is a vertically integrated activewear manufacturer running four factories in Fuzhou, China, with full-package and CMT production, a PVH-accredited in-house testing lab, and OEKO-TEX Standard 100, GRS, and ZDHC credentials. We manufacture for brands including Skims, Victoria's Secret, Calvin Klein, and Tommy Hilfiger, and we build plastic-free performance programs on the OHZEHN-TEX™ platform for brands moving beyond polyester.
What should a $20M to $500M activewear brand demand from a manufacturer?
Four things: vertical integration, in-house accredited testing, verifiable certifications, and a partner who can carry compliance risk instead of pushing it back onto you. At your size, you are past the stage where a trading company or a single sewing factory can serve you, and you are exactly the size where a bad production partner does the most damage. One late core program or one failed chemical test at a major retailer costs more than a year of any per-unit savings.
The brands we work with came to us for one of three reasons. Their factory could sew but could not control fabric, so every quality problem turned into a finger-pointing exercise between the mill and the sewing floor. Their compliance burden grew faster than their factory's testing capability. Or they wanted to develop toward plastic-free performance fabric and their supplier had nothing to offer beyond recycled polyester.
Why does vertical integration matter at this size?
Because at scale, almost every production failure is a fabric failure, and vertical integration puts fabric and garment under one accountable roof. Ohzehn runs four factories in Fuzhou as one group, covering the chain from fabric to finished garment. When the same organization that commits to your delivery date also controls the fabric, there is no gap for problems to hide in.
It changes the money too. One $25M brand consolidated production with us and saved $500k. Not from a cheaper sewing rate, but from what integration removes: the mill's margin stacked on the agent's margin, the air freight that covers for fabric delays, and the re-tests and re-dyes that happen when the mill and the factory answer to different owners. My co-founder JJ Chen runs operations on the factory side; I run the brand side from the US. You get both ends of that in your corner.
Full-package or CMT: which model fits your stage?
Full-package for core programs, CMT where you control a proprietary fabric. That is the pattern across most brands in this cohort, and we run both. The honest comparison:
| Model | Who owns fabric risk | Best for | Watch out for |
|---|---|---|---|
| Full-package (FOB) | The manufacturer | Core programs, replenishment styles, brands consolidating suppliers | Only works if the factory actually controls fabric; ask where the fabric comes from |
| CMT (cut, make, trim) | You | Proprietary or licensed fabrics, brands with a materials team | You become importer of record for materials and own fabric-related defects |
| Trading company / agent | Contractually them, practically you | First production runs, categories outside your core | A margin layer with no factory floor; accountability dissolves when something fails |
| Domestic small-batch | Varies | Speed-to-market tests, made-locally positioning | Capacity ceilings and limited performance-knit fabric options |
| Ohzehn (integrated full-package + CMT) | Us, verified per batch in our own lab | $20M to $500M activewear and intimates brands scaling core programs | We are selective; we build multi-season partnerships, not one-off runs |
Which certifications actually protect you?
The ones you can verify in the issuer's database, held by the factory itself rather than borrowed from a mill. Here is what we hold and what each one means for your risk:
- OEKO-TEX Standard 100, Product Class II. The finished textile is tested against limit values for over 100 regulated substances at the direct-skin-contact class, which is the class that matters for leggings and sports bras.
- GRS (Global Recycled Standard) v4.0, Control Union verified. Recycled-content claims on your hangtags are backed by chain-of-custody audit, not supplier promises.
- ZDHC membership. Wastewater and input chemistry managed to the Zero Discharge of Hazardous Chemicals framework, which your retail partners increasingly require upstream.
- SAC membership. Higg-based facility reporting, the format major retailers ask for during vendor onboarding.
- PVH-accredited in-house testing lab. Our lab is accredited by PVH, the parent of Calvin Klein and Tommy Hilfiger, which is why we can produce for both. In practice it means AATCC and ISO test methods run in-house on your production batches, not just on approval samples: dimensional stability (AATCC 135), colorfastness and pH (AATCC 61, 8, 15, 81, 106, 107), stretch and recovery (ASTM D4964), bursting strength (ASTM D3786).
- Bureau Veritas third-party verification. Independent verification on top of the in-house lab, so you are not taking our word for our own numbers.
Every certificate above has a number, and we hand those numbers over before any commercial commitment so your team can verify them independently. If a manufacturer you are evaluating will not do that, that is your answer.
How is 2026 compliance changing activewear sourcing?
PFAS bans are now the binding constraint on activewear chemistry in the US market. California AB 1817 bans intentionally added PFAS in apparel and textiles, New York's S6291A does the same, and Vermont, Connecticut, Colorado, Washington, Minnesota, and Maine have bans phasing in through 2029. The EU's universal PFAS restriction under REACH is moving toward a broad consumer-application ban. The practical rule for a national brand: one fabric program has to clear the strictest state, so California sets your floor. Our full tracker is at PFAS Clothing Ban 2026.
Our production is PFAS-free and compliant with REACH, SVHC, POP, and GB 18401. That is not a roadmap item; it is how the lines run today, verified by the lab methods above. When a retailer or a state regulator asks your team for chemical documentation, the answer comes from our lab file instead of a scramble across three suppliers.
Can you build plastic-free activewear at production scale?
Yes, and this is where we are genuinely different from every other activewear manufacturer you are evaluating. Alongside conventional performance synthetics, Ohzehn develops OHZEHN-TEX™, a 99.5 percent plant-derived performance fabric platform with true four-way stretch, offered to brands as a licensed ingredient. Consumer pressure on polyester and microplastics is not slowing down, and the brands that pilot plant-derived performance capsules now will own that story in their category. The full material case is in our plastic-free activewear guide.
What that means operationally: you can run your core synthetic programs and a plastic-free capsule with the same partner, the same quality system, and the same lab, instead of managing a separate experimental supplier for the future of your line.
How do you vet us before committing a season?
Start with paper, then people, then product. Ask for the spec pack and verify the certificate numbers against the issuer databases. Get on a call with me and JJ and ask the operational questions your last factory failed on. Then run a development package: we sample, you test our communication speed and our lab reports against what you get from your current supplier, and nobody commits to a season until the samples and the paperwork have earned it. That sequence protects you, and frankly it protects us too, because we build multi-season partnerships and we would rather lose a deal than start one on unverified claims.
Frequently asked questions
What sets the real minimum order quantity at an activewear manufacturer?
Fabric, not sewing. Sewing lines can run small batches, but knitting and dyeing have physical minimums per fabric and per color, so the dye lot sets the real floor. A vertically integrated manufacturer that controls fabric in-house can flex those minimums across styles in ways a sewing-only factory buying third-party fabric cannot. Always ask how the MOQ is built, not just what it is.
Should a scaling brand use full-package (FOB) or CMT manufacturing?
Most brands between $20M and $500M run full-package for core programs and reserve CMT for styles where they control a proprietary fabric. Full-package puts fabric sourcing, lab testing, and quality liability on the factory, which simplifies your operations and consolidates accountability. CMT gives you fabric control but makes you the importer of record for materials and the owner of fabric-related defects. Ohzehn runs both.
How do I verify a manufacturer's certifications are real?
Ask for the certificate number and look it up in the issuer's public database. OEKO-TEX has a label check tool, GRS certificates are verifiable through the certifying body such as Control Union, and ZDHC and SAC list members publicly. A factory that hesitates to hand over certificate numbers for independent verification is telling you the answer. We provide certificate documentation before any commercial commitment.
Can Ohzehn produce plastic-free activewear at production scale?
Yes. Ohzehn Group manufactures conventional performance synthetics and also develops OHZEHN-TEX™, a 99.5 percent plant-derived performance fabric platform with four-way stretch, offered to brands under a licensed-ingredient model. Brands can run conventional programs and pilot plastic-free capsules with the same manufacturing partner, on the same quality system, with in-house lab verification per batch.
