A jacket factory is not a t-shirt factory with a bigger pattern. A technical shell is a shell fabric, a membrane, a lining, an insulation layer, a zipper system and a set of taped seams, and each adds a machine and a skill a general sewing floor does not have. That's why outerwear sourcing follows different rules from every other apparel brief.
Most jackets sold in the United States are imported, so the domestic bench is short. This directory profiles 7 US manufacturers that state on their own websites that they make jackets in American workshops for other brands, teams or businesses, grouped by what they actually build. It's an editorial map built from company websites and public sources, not a roster of factories OneAim owns.
Heads up: We're OneAim, a group of documented United States clothing factories. The companies below are independent US outerwear manufacturers listed on public sources, not members of our group. OneAim's role is separate: we place your production with a documented factory in our group built for your product.
Key Takeaways
- "Jacket manufacturer" is several different businesses. Technical shells, down, heritage wool and leather, and fashion or team jackets need separate machines and skills.
- Seam sealing is a machine, not a technique. A factory without taping or welding equipment cannot make a waterproof jacket.
- Fill power and fill weight are two different specs, and confusing them is the most common down-jacket sourcing error.
- Published minimums are rare. Of the seven makers here, two state a number: around 500 pieces per style at ARGYLE Haus, and 30 or more units for co-branded jackets at Cockpit USA.
- Name your zipper brand on the tech pack, so the hardware that fails first on a jacket can't be quietly substituted.

Why is outerwear a specialist business?
Because a jacket is an assembly, not a garment. A t-shirt is a handful of cut pieces sewn on machines any apparel factory owns. A jacket adds interlinings, linings, insulation, pocket bags, zippers, snaps and, for a waterproof shell, taped or welded seams. A leather jacket needs skiving and heavy-duty machines; a wool varsity body needs a different pressing and finishing routine from a nylon bomber.
The consequence for a brand is that you can't shortlist "a jacket factory." You shortlist a technical-shell factory, a down factory, a leather or heritage-wool workshop, or a fashion cut-and-sew house that has made jackets before. They share a word and not much else.
Down: fill power is not fill weight
Two specs, not one. Fill power measures loft; fill weight measures how many grams of down actually went in. Brands routinely spec one and forget the other. Handling down at all also needs a down-filling room, humidity control and a supply chain for the fill, which is why a factory that lists a dedicated down room is telling you something specific.
How did we choose these jacket manufacturers?
Each company had to pass three checks on its own website: it makes jackets or outerwear, it states that production happens in the United States, and it takes work from outside brands, teams or businesses, through private label, custom collaborations, co-branding or contract cut-and-sew. We left out brand-owned workshops that only make their own line, companies we could only find in directory listings, and companies whose sites describe overseas production for the garment itself. Minimums are quoted only where the company publishes them.
Which US jacket manufacturers make outerwear for other brands?
Better Team USA (Clifton, New Jersey)
A technical and luxury outerwear manufacturer working from a 16,000 square foot facility in northern New Jersey. Its site lists design and development (consultation, pattern making, muslins and prototype samples), a down room, seam tape technology and ultrasonic welding, with sourcing and bulk production under one roof (Better Team USA). An SBA success story describes it as one of the few vertically integrated technical outerwear manufacturers left in the United States, and reports that Ralph Lauren selected it to make outerwear for Team USA's Olympic uniforms (SBA). No minimum is published. Best for taped, welded and down-filled technical jackets.
Golden Bear Sportswear (San Francisco, California)
Established in San Francisco in 1922, Golden Bear makes varsity jackets, motorcycle jackets, bombers and pea coats, handcrafted in San Francisco. The company describes itself as both a premium outerwear manufacturer for other brands and the maker of its own line, and its wholesale page offers full custom collaborations plus access to its archive of designs (Golden Bear). Pricing and delivery are quoted by phone or email; no minimum is published. Best for wool-and-leather varsity jackets and heritage leather styles.
ARGYLE Haus of Apparel (San Fernando, California)
A full-package cut-and-sew manufacturer that says it owns its factory in the San Fernando Valley, with a showroom in downtown Los Angeles. Its outerwear page lists coats, jackets and parkas in down, wool and synthetic fibres, with design, sourcing, technical specifications and quality control in-house (ARGYLE Haus). It states no minimum on design and development, production runs generally around 500 pieces per style or more for e-commerce brands, and 100% American-made production. Those are company claims, not audited figures. Best for fashion outerwear brands moving from development into repeat production.
Lefty Production Co. (Los Angeles, California)
A full-service apparel manufacturer in downtown Los Angeles that says it produces everything locally, in batches large and small, with low minimums for clients who develop their garments with it. Its site highlights bomber jackets made for a band's official tour merchandise and personalised bombers, alongside uniforms for television productions (Lefty Production Co.). No minimum number is published. Best for small-batch bombers and fashion jackets developed from scratch.
Portland Garment Factory (Portland, Oregon)
A creative cut-and-sew and fabrication studio offering custom cut-and-sew manufacturing, product development and prototyping for designers, brands and agencies. Its portfolio includes bomber jackets, tracksuits and lab coats produced for clients (Portland Garment Factory). It doesn't publish minimums. Best for short runs and special projects where development matters as much as volume.
Cockpit USA (New York, New York)
A maker of leather flight and bomber jackets that describes itself as a supplier to the US Government since 1980 and the official supplier of the A-2 leather pilot jacket to the US Air Force. Its site offers personalised existing styles or new special styles for corporate sales and incentive programmes, and its wholesale page states co-branding at minimums starting at 30 or more units with a usual turnaround of 4 to 6 weeks (Cockpit USA). It is a branded maker, so expect co-branded or adapted styles rather than open contract cut-and-sew, and its store lists a separate Made in USA collection, so confirm the origin of any style you adapt. Best for leather and flight-jacket programmes in smaller quantities.
Boathouse Sports (Philadelphia, Pennsylvania)
A custom team apparel maker that says it has produced its clothing in its Philadelphia factory since 1976. Its range includes custom parkas, soft shell jackets and fleece jackets for clubs and programmes alongside team uniforms, and its site says customised team orders can arrive in as little as two weeks (Boathouse Sports). No minimum is published. Best for team and club outerwear with names and logos.

Citation capsule: Jackets for other brands are still made in the United States by a small group of specialist workshops. Manufacturers in Clifton (New Jersey), San Francisco, San Fernando, Los Angeles, Portland, New York and Philadelphia state on their own websites that they make outerwear domestically for outside clients. Only two publish a minimum: around 500 pieces per style for e-commerce brands at one, and 30 or more units for co-branded jackets at another.
Can a t-shirt factory make jackets?
Usually not, and this is the core sourcing risk. A waterproof jacket needs a seam-taping or ultrasonic welding machine. A down jacket needs a down-filling room and humidity control. A leather jacket needs skiving and heavy-duty sewing equipment. Those are separate capital investments a general sewing floor typically doesn't have. Ask to see the machine before you send the tech pack.
Why do tech packs name the zipper brand?
Because the zipper is the most load-bearing, failure-prone component on a jacket. YKK is the default specification in most outerwear tech packs, and naming the brand, the gauge and the slider type stops a factory quietly substituting an unbranded zipper that fails after a season, which is a return no brand can afford. Do the same for snaps, cord locks and seam tape. Our trims and labels guide covers how to specify them.
How do I verify an outerwear factory is real?
Use external evidence, not only the factory's website. Check the business registration and the street address, look for independent coverage such as a government or trade-press profile, and ask for a walkthrough of the floor, in person or on video. A shop that cuts and sews jackets will show you the taping machine, the down room or the leather bench without hesitation.
Then request a paid sample. A factory that can't produce a clean taped seam or a straight zipper setting can't produce a clean run. Our factory vetting checklist lists what to check, and the sample rounds playbook covers how many rounds outerwear usually needs.
Frequently Asked Questions About Jacket Manufacturers
Who makes jackets for other brands in the USA?
The seven manufacturers in this directory state on their own websites that they make outerwear in the United States for outside clients: Better Team USA in Clifton, New Jersey, Golden Bear Sportswear in San Francisco, ARGYLE Haus of Apparel in San Fernando, California, Lefty Production Co. in Los Angeles, Portland Garment Factory in Portland, Oregon, Cockpit USA in New York and Boathouse Sports in Philadelphia. Each suits a different kind of jacket, so start from the construction your design needs.
What is the MOQ for jacket manufacturing in the USA?
Few US outerwear makers publish one. ARGYLE Haus states production runs generally around 500 pieces per style or more for e-commerce brands, with no minimum on design and development. Cockpit USA states minimums starting at 30 or more units for personalised or co-branded jackets. The others quote per project. Ask for the minimum per style and per colour in writing.
What's the difference between fill power and fill weight?
Fill power measures loft, the cubic inches one ounce of down expands to fill, so it tells you warmth per gram. Fill weight is how many grams of down are actually in the jacket. A high fill power jacket with little down is a light layer; a lower fill power jacket with a lot of down is a parka. Specify both, always.
Who makes waterproof technical jackets in the USA?
Waterproof shells need seam taping or welding equipment, which few US sewing floors own. Better Team USA in Clifton, New Jersey lists seam tape technology, ultrasonic welding and a down room among its services, and an SBA profile describes it as one of the few vertically integrated technical outerwear manufacturers left in the United States.
Which US manufacturers make varsity and leather jackets for brands?
Golden Bear Sportswear in San Francisco makes varsity, motorcycle and bomber jackets and pea coats, and describes itself as a premium outerwear manufacturer for other brands as well as its own line. Cockpit USA makes leather flight and bomber jackets and offers co-branded and special styles for corporate programmes and retailers.
