What Can Buyers Verify About the LJUNDERWEAR Factory?
Buyers can review the Shantou production location, eight-stage workflow, sewing and protective-layer processes, in-process quality checks and private-label packing. Capacity, production-line allocation and inspection records are then confirmed for the specific order.
For brands seeking an OEM/ODM route, the practical advantage is one accountable path from pattern and material review through sewing, QC and pack-out at the Shantou production base. Buyers can start with selected routes from 50 pieces, then confirm the applicable MOQ, evidence and line allocation for the named style.
Review the documented LJUNDERWEAR factory workflow before requesting order-level records.
Product formats / Choose a starting point
Which Sport Period Underwear Formats Can You Develop?
Start with the product your customer will wear: a brief, boyshort, training short or active bottom with built-in protection. LJUNDERWEAR can then adjust the fit, protective-panel coverage and construction for the chosen activity.
Performance brief
A close-fitting base for leggings, uniforms or everyday training. Rise, leg openings and panel position can be adjusted.
Best for: a low-profile starting styleSport boyshort
A fuller-coverage option with more leg length. The fit review focuses on ride-up, edge pressure and panel stability.
Best for: coverage and mixed movementTraining short
A short that can be worn alone or under another layer. Pockets, inseam length and waistband design can be specified.
Best for: gym and outdoor collectionsIntegrated active bottom
The protective panel is built into leggings or shorts. This route needs coordinated pattern, fabric and layer approval.
Best for: one-piece activewear conceptsDance and costume brief
A discreet brief for dancewear and fitted costumes. Coverage and layer edges are reviewed under the intended garment.
Best for: dancewear and fitted costumesUse the current Sport Period Underwear range as a starting reference, then confirm which routes require new pattern and test development.

What Should Buyers Include in a Sport Period Underwear Specification?
Tell us the activity, product format, expected movement, fit, protection goal, materials, sizes, branding, packaging and required evidence. A brief that only says “for sport” is not specific enough for pattern or testing decisions.

Protection map / Control movement
How Is the Protection Zone Kept Stable During Running, Yoga and Cycling?
The pattern, panel shape, attachment method, fabric stretch and elastic tension all affect whether the protective area stays in place. These parts are reviewed together while the garment bends and stretches.
Material system / Balance the trade-offs
Which Materials Work for Sport Period Underwear?
No single fabric package suits every sport or style. A development brief may evaluate nylon- or polyester-elastane body fabrics, polyester or cellulose-based contact and absorbent layers, and a TPU barrier. These are material directions, not a pre-approved recipe: final fibre composition, weight, layer order and availability are confirmed in the project BOM.
Use the Fabric Guide to compare material directions, then validate the selected package in the actual construction.
Validation / Separate observation from claims
How Do You Test Sport Period Underwear for Movement, Sweat and Leakage?
Begin with measurements and basic fit. Next, wear the named sample through a defined movement sequence. Use separate functional and wash tests when the product will carry leakage, absorbency, quick-dry or durability claims.
Measurements and static fit
Record the sample revision, size, garment measurements, rise, coverage, waist and leg balance.
Defined activity sequence
Set the movement, duration, garment pairing and observation areas for shift, friction, damp feel and recovery.
Functional and wash evidence
Name the sample, method, condition, result and acceptance decision for leakage, absorption or durability claims.
| Validation area | Approval question | Evidence record |
|---|---|---|
| Garment measurements | Does the sample match the approved specification? | Measurement sheet and tolerances |
| Static fit | Are rise, coverage, waistband and leg openings balanced? | Fit comments by size |
| Movement stability | Does the garment or insert shift, fold, gape or roll? | Named movement sequence and observations |
| Friction points | Do seams, edges or transitions contact high-movement areas? | Wear-review notes and approved photos |
| Sweat exposure | Do materials change hand, cling or recovery under the condition? | Test condition and observations |
| Functional performance | Does the sample meet the agreed absorption and leakage method? | Method, condition and result |
| Wash durability | Do dimensions, stretch, seams, bonds and layers remain acceptable? | Wash protocol and cycle observations |
Use the running period-underwear development guide for one activity-specific protocol. It does not replace the product-specific sample record.

OEM/ODM route / Approval before scale
What Is the OEM/ODM Process for Sport Period Underwear?
We start with the activity and fit, then confirm the protective area, materials and sample. Movement checks and required tests come before the pre-production sample and bulk inspection.
For branding and pack-out decisions, review the labels, packaging and OEM control route.

Which Certifications and Factory Records Can Buyers Verify?
Buyers can verify the OEKO-TEX, Eurofins PFAS, GOTS, ISO 9001 and ISO 14001 records by identifier and original document. Each has a different material, sample or management-system scope, and none proves sport performance on its own.
| Record | Reference | May support | Does not prove |
|---|---|---|---|
| OEKO-TEX STANDARD 100 | 26.HCN.12213 Product Class I Valid to 2027-07-31 | Articles and components named in the certificate scope | Every fabric, color, component or finished sport garment |
| Eurofins PFAS report | EFW726020391 Issued 2026-02-06 | Targeted PFAS reported as ND for the submitted TPU barrier-film sample | Absolute zero PFAS, all fabrics or every finished product |
| GOTS scope certificate | BVC-GOTS-BVCN9928-GOTS-2609-50000871-V1.0 Scope Certificate Version V2.0 Valid 2026-09-04 to 2027-09-03 Holder: Shenzhen Ljvogues Sports Fashion Limited | Reusable period panties and tampons listed as 100% organic cotton in the named scope, subject to style-specific review | That every delivered sport garment is GOTS certified; a valid Transaction Certificate is required for delivered goods |

Buyer questions / Direct answers
What Do Buyers Ask About Sport Period Underwear Manufacturing?
Buyers most often ask how the product differs from regular period underwear, how activity-specific fit is approved, which evidence applies and what changes MOQ or sampling time.
What makes period underwear suitable for sport?
The garment must be developed for a defined activity, with fit, waistband and leg control, protection-zone stability, material recovery and functional performance reviewed together. An athletic silhouette alone does not prove sport suitability.
Can one sport period brief work for running, yoga and cycling?
One style may cover more than one activity after review, but the movement, body position and friction pattern differ. Define the primary activity first and validate any broader use on the approved sample.
How do you prevent the gusset from shifting during movement?
Gusset stability depends on the body pattern, panel shape, attachment method, fabric stretch and waistband and leg fit. Review the approved sample through a defined movement sequence in the key sizes.
Can sport period underwear be seamless or bonded?
Seamless-feel, circular-knit and bonded options can be evaluated when the materials, equipment, protective-panel construction and order quantity are compatible. The approved sample still needs checks for edge strength, panel stability and wash durability.
How should sweat and friction be tested?
Define the activity, duration, moisture condition, garment pairing and observation areas before review. A formal quick-dry or chafe claim requires an appropriate method and result rather than a general wear-test comment.
How is absorbency selected for an active product?
Set the intended use, acceptable bulk, coverage and test claim, then evaluate the named sample under an agreed absorption and leakage method. Higher absorbency should not be assumed to improve fit or movement performance.
What is the MOQ for custom sport period underwear?
Current LJUNDERWEAR company information lists selected product routes from 50 pieces. The quotation must confirm how the minimum applies to each style, color and size. New patterns, custom materials, branded elastic, integrated garments, broad size ranges or special tests may require a higher quantity.
How long does sport period underwear sampling take?
Sampling time depends on the tech pack, material availability, construction, sizes and required tests. The quotation should separate the first prototype, fit revisions, movement review, size checks and pre-production approval instead of promising one fixed sampling time.
Can sport period underwear be produced under the GOTS certificate?
Only where the finished style falls inside the named certificate scope. Scope Certificate BVC-GOTS-BVCN9928-GOTS-2609-50000871-V1.0 covers reusable period panties and tampons listed as 100% organic cotton. A sport style must be checked against that scope, and a valid Transaction Certificate is required before any delivered-product claim is made.
