Strap & Back Style — What to Choose

Back style affects both support distribution and aesthetic. Lock it in on your tech pack before sampling — it drives pattern and trim cost.

Back style Best for Impact support Notes
Racerback (Y-back) Yoga, Pilates, bralettes Low – Medium Most common; keeps straps clear of shoulder blades
Cross-back HIIT, cross-training Medium Distributes load across upper back; distinctive look
T-back Running, gym Medium – High More open back than racerback; good ventilation
Adjustable straight straps Multi-purpose styles Low – High Metal or plastic sliders; slight trim cost addition
Wide-band / encapsulation High impact, D+ cups High Seamed construction; pairs with molded or cut-and-sew cups

Fabrics & Performance Materials

What to put on a sports bra tech pack

Sports bras are judged on support and on how they hold their shape wash after wash. These six items decide both. No tech pack yet? A reference bra or photo is enough to start.

1. Impact level and cup range

Low, medium or high impact, and the cup and band range the style must support.

2. Construction

Encapsulation, compression or both; seamed or seamless; edge finish such as laser-cut or flat-lock.

3. Padding

Removable pocket, fixed moulded cup or none, and the thickness you want.

4. Fabric and performance

Fibre content or swatch, weight, and any wicking or stretch requirement you work to.

5. Straps and back

Racerback, crossback or traditional; adjusters; pull-over or hook closure.

6. Fit and size chart

Fit model or base size, size range, key measurements and the tolerance you accept.

Everyday bras are on the bra manufacturer page, plus-size and nursing in plus-size and nursing, and OEM vs ODM explains which development route fits you.

How we keep sports bra bulk the same as your sample

A sports bra that loses its underband recovery stops supporting, and that does not show at inspection. We treat it as a separate step.

1

Recovery is tested before we cut

Elastic recovery is wash-tested on the production fabric. The report goes to you before cutting starts. AQL inspection at the end checks visible defects.

2

Elastic from one designated supplier

The spec sheet ships with your goods, so your next reorder can be matched exactly.

3

Same batch as your sample

The elastic in your sample and in your bulk order comes from the same batch and dye lot.

Payment follows inspection: 30% deposit to start production, 70% balance after you approve inspection. How we run QC →

Frequently Asked Questions

What is the difference between encapsulation and compression sports bras?

Compression sports bras press both breasts against the chest as one unit, effective for smaller cup sizes at low to medium impact. Encapsulation bras hold each breast separately in its own cup structure, providing independent support that works across a wider cup range and at higher impact levels. Many of our high-impact styles combine both: compression lining inside an encapsulation outer shell.

Can you make a yoga bra with a seamless or minimal-seam construction?

Yes. Seamless knit styles are available as part of our ODM library. For OEM orders, we offer laser-cut edges and flat-lock seaming to reduce pressure points. Let us know the construction priority, minimal seams for feel, or bonded edges for shape, and we’ll recommend the right method.

Do you offer removable padding in sports bras?

Yes. Most of our medium-impact styles include a pocket for removable foam cups. Padding thickness ranges from 3 mm to 12 mm. For high-impact styles without underwire, we typically go with a fixed moulded cup for structural integrity, but can add a removable pad pocket on request.

What is your MOQ for sports bras?

50 pieces per style per colour, sizes mixed freely.

How long do samples and bulk production take?

ODM samples take 7 to 10 days and new OEM patterns 10 to 14 days. Bulk production takes 30 to 45 days from sample sign-off.

How do I know bulk will match my approved sample?

Elastic recovery is wash-tested on the production fabric and you receive the report before cutting. Elastic comes from a designated supplier, the spec sheet ships with your goods, and sample and bulk use elastic from the same batch and dye lot.

How does payment work?

30% deposit to start production. The 70% balance is due after you approve inspection.

Do you sign NDAs?

Yes. We sign an NDA before spec review, and your design is not shown to other buyers.

Do you ship DDP or FOB?

Both. We quote FOB Shanghai or Ningbo, or DDP delivered to your door, whichever suits your import set-up.

What customisation options are available for sports bras: colours, prints and branding?

Four options at standard MOQ: (1) Pantone solid colour. Performance fabric dyed to any Pantone TPX/TCX code, no tooling cost; (2) all-over digital print (AOP) on nylon / elastane panels before cut-and-sew, unlimited colours; (3) placement print or embroidery for a brand logo on front, back, strap or underband; (4) custom woven label, care label and packaging to your spec. Send your colour references and artwork files with your enquiry and we will include all customisation options in the quote.

Can you make plus-size sports bras, and will the support hold in larger sizes?

Yes. Our standard size range is XS to 3XL, graded in-house on our CAD system. For medium and high-impact styles in larger sizes, we use a wider underband, stronger elastic, and either full encapsulation construction or a combined compression-plus-encapsulation shell. Include your full size run when you enquire and we will confirm grading feasibility and construction recommendation before sampling.

What sports bra styles and support levels can you produce?

We cover all three support tiers. Low-impact: bralette and crop-top styles in stretch fabric, suited to yoga and pilates. Medium-impact: racerback and cross-back styles with a moulded or contour pad, suited to cycling and gym. High-impact: encapsulation styles with underwire and two-part cups, or compression styles with a wide underband and power-mesh panel, suited to running and HIIT. Front-zip, longline and tank-bra hybrids are also available from our pattern library.

What fabrics work best for sports bras?

Nylon-elastane (80/20 or 78/22) is the industry standard: high stretch recovery, moisture-wicking and holds its shape after repeated washing. Polyester-elastane is a lower-cost alternative with good durability but slightly less recovery. For premium yoga and low-impact styles, four-way stretch supplex or recycled nylon (e.g. ECONYL) adds a sustainability story. Power mesh is used for ventilation panels in high-impact styles. Tell us the activity level and price point and we will recommend the right weight and construction.

What Sports Bra Brands Say

“

We sent a fabric swatch and a sketch. They built the pattern, confirmed the elastic recovery spec before sampling, and the racerback held its shape through fifteen wash cycles before we signed off on bulk.

Mia · Soleil Active

Canada · Yoga & Pilates brand · Low–medium impact

Yoga brand

“

High-impact sports bras are hard to source in extended sizes without the support falling apart at XL+. We got consistent compression from XS through 3XL on the first bulk run. The underband recovery report they sent before shipment settled any doubt.

Dan · Apex Athletics

USA · Gym & crossfit brand · High impact

Size-inclusive

“

We needed cross-back construction with a custom print across the panel seams. The print alignment spec was harder to pin down than a plain-colour bra. They flagged the registration issue before bulk and fixed it on the second sample.

We run a boutique studio and wanted branded bras for our members without ordering 500 units. Fifty pieces, two colours, woven label on the underband. We have reordered twice without going back to sampling.
