The Custom Sports Bra Manufacturer’s Support System: Three Tiers, Three Constructions
Most factories cut two compression pull-over blocks and outsource anything structured. As a custom sports bra manufacturer we build every support tier in every construction, so your full bra range ships from one floor.
Soft compression bralette, pull-on, removable pads.
Light molded cup, soft band, wire-free shaping.
Compression shell with a light cup for a clean line.
Firm racerback pull-on with power-mesh back.
Shaped molded cups, structured band, defined C–D support.
Compression plus cups plus power-mesh, no hook-eye.
Maximum compression, high neck, wide locked band.
Full molded, underwire-channeled cups, hook-eye band.
Compression, encapsulation, and adjustable hook-eye together.
All nine cells run on our own cut-and-sew, molded-cup, and channeling lines — one dye batch across the range, no subcontracting, no cross-supplier color drift.

The Cup and Band Build Behind Our High-Impact Sports Bras
The cup, pad, strap, and band are the buy decision for any high impact sports bra manufacturer. Here is every build we tool and sew in-house — not a “fully customizable” line, an actual capability list.
Cup & pad
- Molded contour cup — heat-shaped, holds its form wash to wash.
- Removable-pad pocket — sewn-in retention opening, no curl.
- Sewn-in spacer pad · wire-free support across every tier.
- Underwire channeling — encased, no poke, for high-impact encapsulation.
Strap systems
- Racerback · cross-back · classic adjustable · convertible.
- Wide cushioned straps — large-cup load spread.
- Reinforced strap anchor — no dig under high impact.
Band, closure & seams
- Pull-on band · structured underband · multi-row hook-eye.
- Power-mesh side panels and wings — large-cup stability.
- Flatlock · bonded heat-weld · coverstitch seams, no chafe.

Match my support tiers to fabricReal Band×Cup Grading for Wholesale Sports Bra Sizing
A 32A and a 38DD are not a small and a large of the same block. We grade band and cup as two independent axes, so your large cups fit like the sample instead of a stretched medium.
| Band \ Cup | A | B | C | D | DD |
|---|---|---|---|---|---|
| 30 | 30A | 30B | 30C | 30D | 30DD |
| 32 | 32A | 32B | 32C | 32D | 32DD |
| 34 | 34A | 34B | 34C | 34D | 34DD |
| 36 | 36A | 36B | 36C | 36D | 36DD |
| 38 | 38A | 38B | 38C | 38D | 38DD |
| 40 | 40A | 40B | 40C | 40D | 40DD |
| 42 | 42A | 42B | 42C | 42D | 42DD |
Two axes, graded separately
Band circumference is graded on one axis — underband length, wing depth, and closure rows. Cup volume is graded on a separate axis — cradle width, cup depth, and apex position.
- Proportional regrading of cradle, underband, wing, and strap anchor per cup size, not a single linear S–XL rule.
- Large-cup treatment (D, DD): wider wings, power-mesh side panels, wider cushioned straps, reinforced strap anchor.
Linear-grading a 38DD from a 34B block gives a gaping band, cup spillage, digging straps, and a rolling underband — the failure that concentrates returns in exactly the sizes a size-inclusive brand promises.
Fabric and Support Specs — From Seamless to Compression Sports Bras
From a seamless sports bra manufacturer’s circular-knit to a compression sports bra supplier’s power-mesh, every impact tier is mapped to its fabric, GSM, stretch, and support build — measured before the first bolt is cut.
| Impact tier | GSM | Spandex | 4-way stretch | Support construction | Power-mesh panel | Fabric | Wicking |
|---|---|---|---|---|---|---|---|
| Low | 200–240 | 10–14% | 55%+ | Compression / light molded | Optional | nylon-spandex, recycled-poly elastane | High |
| Medium | 220–260 | 14–18% | 60%+ | Compression / combination | Back panel | poly-spandex, power-mesh | High |
| High | 260–320 | 16–20% | 65%+ | Encapsulation (molded + channeled) / combination | Side panels + wings | poly-spandex + power-mesh, bonded | High |
| Seamless | 220–250 | 16–20% | 70%+ | Molded one-piece, bonded edges | Knit-in | nylon circular-knit | High |
GSM, stretch elongation, and compression retention are read per fabric lot before cutting. Color held to ΔE ≤1.5 per fabric lot; recycled (GRS) and brushed options available on request.

Sports Bra Manufacturing — Questions Buyers Ask
The support tiers, minimums, sampling, grading, and reorder answers that decide whether we are your factory.
Do you make high-impact encapsulation bras in-house, or just compression pull-ons?
Both. We build all three support tiers on our own floor — compression pull-ons, combination bras, and full encapsulation with molded cups, underwire channeling, and hook-eye bands. Cup tooling and channeling are in-house, so your whole bra range runs through one dye batch with no subcontracting and no cross-supplier color drift.
Do you grade real band×cup sizes, or only S–XL?
Real band×cup. We grade band 30–42 and cup A–DD as two independent axes, with proportional cradle, wing, underband, and strap-anchor regrading per cup volume. Large cups get wider wings, power-mesh side panels, and wider straps, so a 38DD fits like the sample instead of a stretched medium.
Are longline and racerback bras made in-house?
Yes. Longline, racerback, strappy, seamless, high-neck, zip-front, encapsulation, and nursing are all cut and sewn on our own floor. Seamless runs on a circular-knit line; the structured styles run on cut-and-sew with molded-cup tooling — all under one roof, one dye batch.
How do you build the cup — molded, removable pad, or underwire?
All three. We tool molded contour cups, sew removable-pad pockets with retention openings, and channel underwire for high-impact encapsulation. Wire-free support is available across every tier. Tell us the support level and we recommend the cup build, or build exactly to your tech-pack.
What does MOQ 300 mean for a structured bra — per size or total?
Total. MOQ is 300 pieces per style, size-split across your band×cup range as you choose, not 300 per size. A structured encapsulation bra carries the same 300 MOQ as a simple bralette — the cup tooling does not raise the minimum.
How fast is a sample, and what does it cost?
A sample is 1 piece at USD 45, ready in 5 working days when the fabric is in stock, or 12 working days for to-order fabric. You approve support level, cup build, fit, fabric, and color on the sample before any bulk is cut.
How consistent is color across reorders?
We hold Pantone color to ΔE ≤1.5 and read a spectrophotometer value per fabric lot in your pre-shipment package. Your reorder black matches your first-order black — and matches the legging you ordered in the same batch, so a coordinated bra-and-legging set stays consistent.
What is the private label minimum for sports bras?
Private label runs on our existing bra blanks across the three support tiers at a lower entry than full OEM, with your woven label, hangtag, and packaging. It is the fastest route to a first PO; send us your label kit and target support tiers to confirm.
