Our Grey Marle Seamless Racerback Sports Bra is made to order in Bangladesh for activewear brands, gym and studio ranges, sports retailers and private label fitness labels in the USA, the UK, Germany, Canada and Australia, and for growing programmes in Sweden and Poland. As a clothing manufacturer, supplier, wholesaler and exporter working from Bangladesh, we build this style to your size chart, your label and your packing spec, with a seamless body knitted in one piece, a racerback and a wide knitted in ribbed underband.
A sports bra is judged on its band and its seams, so this style is patterned on a proven block, sampled in the real knit and checked against the size chart and the shade standard before a single bulk panel is cut. It is cut and sewn in our own unit, finished by hand and checked piece by piece before it is folded.
Buyers usually look at this style alongside the burgundy strappy back sports bra, olive mesh panel sports bra and the sports bra. The full range sits on our products page.
- Seamless body knitted in one piece, with no side seams.
- Racerback cut with a bound scoop neckline.
- Wide ribbed underband knitted in as part of the body.
Grey Marle Seamless Racerback Sports Bra: Design and Construction Detail
The grey marle sports bra is knitted as one piece on a circular machine, so the body has no side seams at all: the scoop neckline, the racerback and the wide ribbed underband all come off the machine as a single garment shape, with the rib of the band knitted in tighter than the body above it. The neckline and armholes are finished with a clean bound edge, and the marle face gives the whole piece its soft heathered texture.
Seamless knitting moves the discipline from the sewing line to the machine programme: the stitch density, band depth and racerback shape are set in the programme and checked on the first pieces off the machine, size by size. The bound edges are applied under a guide so they sit at an even width, and every piece is checked at the neck, armholes and band before folding.
Grey Marle Seamless Racerback Sports Bra: Fabric, Fit and Comfort
The cloth is a nylon elastane knit with the grey blended as a marle before knitting: light and dark grey yarns feed the machine together, so the heathered texture runs through the whole garment and cannot wash out. The body knit is smooth and even, the band is a firmer rib, and both read clearly in the fabric view.
The fit follows a close athletic block with a racerback that narrows between the shoulders, graded across the women’s size run by the knitting programme so the band depth and neckline stay in proportion at every size. One size chart and one fit approval cover the whole order, and the marle standard is held for repeats.
Seamless styles reorder on comfort of make as much as on looks: there is nothing inside the garment to rub, and buyers in Sweden and Poland run this marle racerback as their seamless core for exactly that reason. The yarn blend, the machine programme and the size chart are held on one file, so the piece a customer buys this spring is knitted the same way next spring. The marle ground does the quiet work of keeping the shade even under studio light, and every piece is checked at the band and the bound edges before it is folded.

Pattern Making and Size Grading
A good Grey Marle Seamless Racerback Sports Bra starts with the pattern and the band. The block is drafted to your size chart with the cup, band and strap set first, then graded across the full size run so the neckline and armhole stay in proportion at every size. A pre-production sample is sewn first and checked flat, worn and measured, and small corrections are made before the bulk markers are laid.
Private Label and OEM Production
Private label is where this Grey Marle Seamless Racerback Sports Bra becomes unmistakably yours. The woven main label sits at the back band, size and care labels follow your market rules, and swing tags, stickers and polybag print carry your artwork. Neckline shape, strap layout and band depth can all be set to your house pattern at the sampling stage, so bulk matches the approved sample exactly.
Bulk Production and Quality Control
Bulk production runs on a shade banded cutting spread, so the front, back and band of one piece always come from the same cloth length. Each bundle passes through inline checks at the band, the straps and the armholes, and a final audit sample is measured against the size chart before cartons are sealed. Faulty pieces are pulled at the line, never packed and hoped for.
Fabric and GSM Options
The cloth story matters as much as the cut. This style uses seamless nylon elastane knit with a marle face, and the same pattern can be sewn in a plainer knit or a marle when your range needs a step across the season. Buyers in Sweden and Poland often take one block in two colourways as a core and a statement colour, sharing a single size chart and fit approval across the whole order.
Print, Embroidery and Branding Methods
The grey marle seamless bra takes branding the activewear way: a small printed or embroidered mark on the band or the chest where the design leaves room, and your woven label at the back. Every branding element is sampled on the real garment first so placement and size are approved before bulk, and your labels and tags finish the private label build.
Packing, Dispatch and Lead Times
Finished pieces are pressed, folded and polybagged one piece per bag unless your spec says otherwise, and mixed size ratios can be packed against your list. Cartons are marked by size and colour with a packing list inside. Lead times are confirmed at order stage and held with weekly production updates until the goods leave Bangladesh.
Pricing and How to Get an Exact Quote
An exact quote needs four things: the fabric and weight, the strap and band work, the size ratio, and the delivery point. With those fixed, pricing is firm and itemised, covering cloth, trims, packing and finishing. Two builds of the same style can price quite differently, so we always quote the build you approved, not a generic rate.
Why Buyers Choose Siatex Bangladesh
Buyers choose Siatex because the same factory team handles sampling, bulk and finishing under one roof in Bangladesh, and because the Grey Marle Seamless Racerback Sports Bra they approve is the one that arrives. Programmes running into the USA, the UK, Germany, Canada and Australia are reordered season after season on that simple basis: honest fabric weights, measured samples and cartons that match the packing list.
Frequently Asked Questions
What does seamless mean on the grey marle sports bra?
The body is knitted in one piece on a circular machine, so there are no side seams to sew, rub or show through a top. The underband rib and the racerback shape are knitted in as part of the same piece, not added afterwards.
Is the racerback bra knitted or sewn from cut panels?
Knitted. Only the bound edges at the neck and armholes are sewn on after knitting. The cup area, body and band come off the machine as one garment, which is why the marle texture runs unbroken around the whole piece.
Will the grey marle shade stay even across sizes?
Yes. The marle yarn blend and the machine programme are held on file, and first pieces of every size are checked against the standard before the run continues, so the full size run arrives as one even shade family.
Does the underband carry any lettering?
No. The knitted in underband is plain rib with no words or logos worked into it, so your own woven label at the back band and your artwork on the tag and packing carry the branding.
