Women's Seamless Sports Bra Medium Support
Women's sports bra in 60% Nylon, 32% Polyester, 8% Spandex, with medium support build, knitted seamlessly in Yiwu and produced to order from 300 pieces per colour.
Product Overview
Women's Seamless Sports Bra Medium Support is a women's sports bra made at Tanbei's own factory in Yiwu, Zhejiang. The fibre content published for this style is 60% Nylon, 32% Polyester, 8% Spandex. The body is built by seamless circular knitting, and the construction detail that defines it is medium support build. Nothing about the style is fixed: the fabric, the colour, the trims and the labelling are all developed for the brand placing the order, so the sheet below is a starting point rather than a catalogue item.
Key Benefits
- Produced in Tanbei's own Yiwu factory, so the sampling team and the production line are the same people
- Knitted in one piece on seamless machines, so there is no side seam to chafe under a waistband or a pack strap
- The medium support build is run in-house on the same order rather than sent out to a finishing house
- Minimum 300 pieces per colour, negotiable when several styles share one fabric and colour
- Fibre content is quoted as the mill supplies it, not rounded into a marketing description
- Samples in about one to two weeks, with written comments answered on the next round

Use Guide
- Send a reference garment or a tech pack and the sample room works from it directly
- Confirm the fabric first: it decides the hand feel, the price and the lead time
- Approve a lab dip before bulk, because colour is the most common reason a shipment is rejected at retail
- Add styles in the same fabric and colour to bring the minimum per style down
Quality Control
- Fit and appearance checked against the approved sample before the line runs
- Written comments on every sample round are checked one by one on the next round
- The factory has passed a BSCI audit and buyers are welcome to visit during their own production
Materials
- Main fabric: 60% Nylon, 32% Polyester, 8% Spandex
- Fabrics are sourced through Tanbei's own sourcing team, which works with mills close to the Yiwu factory
- Sustainable fabric options are sourced on request as part of the company's published sustainability commitment
- Trims are developed for the order: aglets, zippers, drawcords and tapes
Manufacturing Process
- Fabric development and colour approval with the sourcing team
- Seamless knitting of the body in one piece
- Sewing and linking at the Yiwu factory
- Applied finishing: medium support build
- Inspection, pressing, folding and packing to the brand's artwork
Certification And Audit
Production runs in a BSCI audited factory in Yiwu, Zhejiang. Which compliance documents a shipment needs depends on the destination market, so certificates are sent per order rather than posted publicly. No other certification is claimed here, because the manufacturer publishes none.
Customisation Options

- Trims developed for the order: aglets, zippers, tapes and drawcords
- Neck labels, care labels, hang tags and polybag artwork to the brand's design
- Fit and grading adjusted by the technical team before production
- Applied finishing changed or removed: this style currently carries medium support build
How It Compares With The Alternatives
A construction comparison against the other ways of solving the same brief. Nothing here is a performance claim against a named competitor.
| Against the same garment made cut and sew | A seamless body has no side seam and repeats its compression from the knitting programme; a cut and sew body can carry linings, pockets and structured panels a knitting machine cannot. This style is seamless. |
| Against buying it from a trading company | The price here comes from the factory that makes it, so a question about why a fabric costs what it does has an answer. The sample room and the production line are the same people in Yiwu. |
