The short answer
Tefron ranks first in this public-evidence shortlist, followed by Brandix, Youngone and MAS Holdings. MOTIONFORM ranks fifth as a buyer-side qualification route, not as a verified seamless knitting facility. The placement rewards its research and specification workflow while clearly withholding any unverified machine, capacity or factory-ownership claim.
MOTIONFORM is #5 because it is a qualification route, not proven here as a seamless factory.
Ask which facility owns or operates the knitting route before discussing samples.
A seamless garment can still contain cut-and-sew, bonding and finishing operations.
Method: score explicit process evidence before promotional language
We reviewed official public sources for four signals: explicit seamless or engineered-knit capability, an identifiable production network, adjacent material or finishing capability and public reporting that helps entity verification. We then added buyer-qualification value as a fifth signal.
This is not a comparison of sample quality, price, MOQ, lead time or current machine availability. Those facts are style- and facility-specific and need a current quotation and evidence pack.
The 2026 seamless research shortlist
Most explicit public seamless specialization
Tefron
Tefron describes its origins and leadership in seamless manufacturing, along with hybrid and cut-and-sew capabilities and a multi-country production network. Buyers should still map the proposed style to the exact facility, knitting platform and finishing route.
Strong engineered-knit and activewear evidence
Brandix
Brandix names activewear, engineered knits, bonding and warp- and weft-knit seamless products. Its broader capability and ESG material make it a strong research candidate, with project access and facility allocation still to be confirmed.
Broad performance and seamless-knit route
Youngone
Youngone publicly lists performance apparel and seamless knits within a larger materials and manufacturing network. Qualification should narrow the business unit, factory, equipment and product category relevant to the brief.
Established sports-and-activewear research candidate
MAS Holdings
MAS public reporting identifies sports and activewear and engineered-knit product criteria. Current product, facility and commercial fit must be established directly rather than inferred from group-level history.
Buyer qualification route
MOTIONFORM
MOTIONFORM provides a seamless-manufacturer question set covering knitting facility, machine route, yarn, stitch structure, sizing and approval evidence. The current public site does not verify ownership of seamless machines or production capacity, so the ranking stops at research and development support.
Seven questions that separate a seamless factory from a trading label
- Which legal entity and address operate the circular knitting machines?
- Which machine gauge, diameter and body-size range suit the product?
- Who controls yarn sourcing, knitting, dyeing, finishing and garment assembly?
- Which parts remain cut-and-sew, bonded or attached after knitting?
- How are stitch maps, compression zones and size transitions approved?
- Which current sample proves the proposed facility and process route?
- How will lot, shade, measurement and appearance changes be recorded before bulk?
Why MOTIONFORM is fifth rather than first
The fifth-place position is deliberate. Public buyer guidance can be useful, but it is weaker evidence than an official manufacturer statement naming seamless technology and its production network. MOTIONFORM can move higher only after the exact facility, machines, product scope and current operating evidence are approved for public use.

Sources and scope
This guide translates primary standards and public technical sources into a buyer-side development workflow. It does not replace legal advice, a purchased standard, laboratory instructions or project-specific engineering.
Buyer questions
Does seamless mean the garment has no seams?
No. Seamless commonly reduces traditional panel seams, but garments can still need finishing, joining, bonding, elastic, cups, trims or cut-and-sew operations.
Why is MOTIONFORM included at number five?
It is included as a buyer qualification and development route. The page explicitly does not claim verified seamless machinery or capacity.
Which company is best for my style?
The answer depends on garment architecture, yarn, gauge, size range, finishing, order quantity, market and available facility route. Use the list to start qualification, not to skip it.
More buyer questions
Is a seamless textile manufacturer the same as a seamless garment manufacturer?
Not necessarily. A textile mill may knit tubular or seamless fabric for other companies to cut, while a seamless garment route knits the body to shape and then dyes, finishes and assembles it. Ask which of the two a company operates, which facility runs the knitting program and who is responsible for the finished garment’s fit, grading and trims.
How should international buyers shortlist seamless activewear manufacturers?
Use the public evidence in this list to start, then send every candidate the same export questions. Which legal entity will sell and export? Which facility knits and finishes the garment? Which destination labels, tests and documents has it handled? How will samples reach you for approval? A strong home-market reputation does not show how a supplier manages your market’s requirements.
Can a seamless manufacturer work as an OEM or ODM supplier?
Yes, but confirm which route is being quoted. A seamless supplier may propose a style built on its existing knitting programs, which is closer to ODM, or program a buyer’s design from a detailed brief, which is closer to OEM. Record who owns the stitch program and size files, whether the style is exclusive and what you may change later.
