Sports Bra Manufacturer in China: Support Levels, Cups & MOQ
A sports bra is the hardest garment in an activewear line to get right — and the one most brands get wrong. Support, cup structure and fabric recovery decide whether a customer re-orders or quietly switches brands after one wash. Most buyers ask a factory "can you make a sports bra?" when the real question is "can you make the right support level, cup and fabric for my customer, at a workable MOQ?" This guide walks through what to specify, what to ask a sports bra manufacturer in China, and how low-MOQ private label actually works — the same know-how behind our yoga wear manufacturer line and the yoga & activewear collection.
Support Levels: Light, Medium, High
The first decision is how much support the bra must deliver. Get this wrong and a high-impact runner ends up in a light-support bralette, or a yogi gets over-compressed in a high-impact cage. Define the level by activity, not by price:
| Level | Best for | Construction | Compression |
|---|---|---|---|
| Light | Yoga, Pilates, walking, lounging | Unlined or lightly lined, wide band, pullover | Low — holds in place, no squeeze |
| Medium | Gym, cycling, hiking, dance | Underband + racerback, light cup, keyhole | Moderate — reduces bounce ~50% |
| High | Running, HIIT, jumping, court sports | Encapsulation + compression, padded straps, bonded seams | Firm — reduces bounce 70%+ |
Cups: Molded, Sewn-In Pad, or Removable
The cup is where comfort and returns are won or lost. There are three structures, each with a clear trade-off:
| Type | Feel | Best for | Watch-out |
|---|---|---|---|
| Molded (pre-formed) | Smooth, shaping, no pad shift | Medium/high support, premium sets | Needs correct cup size; wrong shell looks bulky |
| Sewn-in pad | Soft, no removal, no lost pads | Light/medium, everyday | Harder to relayer; less adjustable |
| Removable (pocketed) | Adjustable, easy care | All levels, first retail runs | Pads migrate in wash if pocket is shallow |
For a first production run, a removable pad in a deep pocket is the lowest-risk choice: the customer can adjust, and you avoid the returns that come from a molded cup that fits one body shape only. When the fit is proven, move to molded for a premium line.
Fabric: Nylon-Spandex and the Recovery Number
A sports bra lives or dies on fabric recovery — how fast it springs back after a stretch. Write the blend, the GSM and the spandex percentage in the tech pack, because "nylon-spandex" alone tells the factory nothing:
| Blend | Spandex | GSM | Best for |
|---|---|---|---|
| 78% nylon / 22% spandex | 22% | 200–220 | High-support, sculpting, butt-lift |
| 80% nylon / 20% spandex | 20% | 180–200 | Everyday medium-support sets |
| 75% nylon / 25% spandex | 25% | 210–230 | High-impact, fuller-bust containment |
| Modal / Tencel blend | 5–8% | 160–180 | Light-support, heat-prone markets |
Construction Details That Matter
- Underband — the real support driver. Width 3.5–5cm, bonded or double-layered, with a firm elastic core. Too narrow = digging; too soft = bounce.
- Seams — flatlock (four-needle six-thread) sits flat against skin; overlock rubs on a high-impact run. Bonded seams are premium but need the right press.
- Straps — padded and adjustable for high support; racerback or convertible for medium. Thin straps on a high-impact bra = shoulder pain.
- Closures — pullover for light/medium; hook-eye or zip for high support and fuller-bust ease.
- Edge finish — soft encased elastic or laser-cut sealed edge; a raw band rolls and chafes.
Sizing & Fit: Full-Bust and Plus-Size
Sports bras are usually graded in S–XL by bust, but fuller-bust and plus-size buyers need a different approach — band and cup scale at different rates. Grade before the first sample, not after the first complaint:
| Profile | Grade note | Support priority |
|---|---|---|
| Standard S–XL | Band + cup scale together | Balanced, everyday |
| Fuller-bust (DD+) | Wider band, deeper cup, side support | Containment without squeeze |
| Plus-size 1X–5X | Extended grading, wider band | Hold shape, no roll |
Our Africa plus-size manufacturing and Middle East modest wear collection already grade for fuller and extended bodies, so a sports bra for those markets slots into the same size logic. A bra that fits a fuller bust is also the basis for a modest, full-coverage activewear set.
MOQ, Lead Time & FOB
A sports bra follows the same low-MOQ logic as the rest of the catalogue — prove the fit small, then re-order the same programme:
| Parameter | Standard | Note |
|---|---|---|
| MOQ | 100 pcs per style / colour | Bra + coordinating legging = two styles |
| Lead time | 10–15 days | From approved sample |
| Price basis | FOB from $4.08 | China port; freight by your forwarder |
| Re-order | Programme locked | 3rd order matches the 1st |
We quote FOB (China port) only — we do not pretend to be a door-to-door (DDP) shipper. You appoint your own freight forwarder; we prepare the export documents (commercial invoice, packing list, HS code, certificate of origin) so your side clears cleanly at Jebel Ali, Jeddah or elsewhere.
Private Label & Custom
- Custom logo & label — heat-transfer, woven tag or printed care label, your brand not ours.
- Custom packaging — polybag, belly band and mailer box matched to your unboxing.
- Cup & fit — send a reference or target size run; we mould to your cup spec and grade S–XL (and extended plus).
- Tech pack ready — we work from your spec or build the bra from a reference, a support target and a price.
How an Order Flows
- Quote — send a support brief or reference photo; we return FOB per style/colour with fabric and MOQ.
- Sample — we sew one bra, run the recovery and opacity check, ship it for fit approval (10–15 days).
- Bulk — on approval, production slots in; same pattern, same dyed lot, locked for re-order.
- Ship — FOB China port, full export docs, your forwarder takes it from there.
Frequently Asked Questions
What support level do I need for my sports bra?
Match the level to activity: light for yoga, Pilates and walking; medium for gym, cycling and hiking; high for running, HIIT and court sports. The real control is an outcome — "reduces bounce 70% in a run" — not the word "high," because factories interpret support levels differently.
Molded cup or sewn-in pad — which is better?
For a first retail run, a removable pad in a deep pocket is lowest-risk: the customer can adjust and you avoid returns from a molded cup that fits one shape only. Move to a molded cup for a premium line once the fit is proven. Sewn-in pads sit between, soft but less adjustable.
What fabric is best for a high-support sports bra?
A nylon-spandex blend of 75–80% nylon with 20–25% spandex at 200–230 GSM gives firm recovery for high-impact containment. The control number is spandex percentage and GSM, not just "nylon-spandex" — spec it in the tech pack so bulk matches the approved sample.
How is sports bra sizing handled for fuller-bust and plus-size buyers?
Grade for two profiles: fuller-bust (DD+) needs a wider band, deeper cup and side support, while plus-size buyers need extended 1X–5X grading with a firmer band that holds shape. Never scale up a straight-size bra — it loosens the band and shallow the cup so the bra offers no support.
How are shipments priced?
FOB from a China port, from $4.08. We prepare the commercial invoice, packing list, HS code and certificate of origin; your freight forwarder handles international transit and destination clearance. We do not quote DDP or door-to-door, so the landed cost stays in your control.
