Matching Sports Bra and Leggings Set – Product Specification & Description

The Matching Sports Bra and Leggings Set is engineered for high-performance fitness brands, private label importers, and sporting goods distributors. Designed for dynamic multi-directional movement, the set pairs a medium-to-high support sports bra with a high-waisted, squat-proof compression legging.

Manufactured in our 12,000-square-meter facility equipped with automated German seamless knitting and Japanese 4-needle 6-thread flatlock machines, this set delivers consistent stitch density, precise tension control, and reliable batch-to-batch uniformity for B2B partners.

Key Features

Anatomical Compression Fit: Targeted muscle support panels reduce vibration during high-impact training while maintaining full range of motion.

100% Squat-Proof Opacity: High-density interlock knit prevents transparency under maximum elongation and tension.

Moisture-Wicking & Breathable: Hydrophilic yarn treatment accelerates sweat evaporation, maintaining a dry microclimate against the skin.

Friction-Free Seams: 4-needle 6-thread flatlock stitching eliminates chafing and skin irritation during repetitive friction cycles.

Roll-Resistant Waistband: Multi-layered waistband construction with internal elastic retention prevents rolling or slipping during deep squats and flexion.

Materials & Construction

Yarn Selection: Utilizes filament nylon yarn combined with high-modulus spandex core-spun yarn for superior tensile strength and snap-back elasticity.

Knitting Technology: Produced on SANTONI circular knitting machines, minimizing side seams for a clean aesthetic and structural integrity.

Dyeing & Finishing: Eco-friendly reactive dyeing process certified by OEKO-TEX Standard 100 (Tested and verified by independent third-party laboratories such as SGS / Intertek). Anti-microbial and UV-protection finishes applied per client specification.

Reinforced Stress Points: Bar-tacked at high-tension areas including strap anchor points, waistband seams, and crotch gusset intersections.

Sizes & Customization

Size Range: Standard XS to XXL (Based on US/EU body block specifications; custom grading charts and spec sheets accepted).

OEM/ODM Options:

Branding: Custom heat-transfer labels, woven labels, silicone branding, and laser-engraved hardware.
Design Modification: Altering rise height, inseam length, strap configuration (crossback, racerback), and removable cup padding density.
Color Matching: Pantone TCX / TPX lab-dip matching within 3–5 business days (Delta E tolerance <1.0).

Applications

Gym & Fitness Training

Weightlifting, CrossFit, and high-intensity interval training (HIIT) requiring durable, high-tension support.

Studio & Yoga

Pilates, hot yoga, and barre requiring zero-distraction flexibility and moisture regulation.

Athleisure & Retail

Quality Control

Quality control follows a strict 4-stage inspection protocol executed by certified QA inspectors:

01/

Raw Material Inspection: Testing incoming yarn batches for tensile strength, denier consistency, and shade variation.

02/

In-Line Inspection: Monitoring yarn tension, stitch count, and seam alignment during knitting and assembly lines.

03/

Semi-Finished Testing: Dimensional stability testing after heat-setting to strictly control post-wash shrinkage within +/-3%.

04/

Final AQL 2.5 Inspection: Comprehensive audit covering finished dimensions, seam strength, color uniformity, and packaging integrity prior to shipment.

Packaging & Private Label OEM/ODM

Individual Packaging: Recyclable polybag with size sticker and desiccant. Custom zip-lock or biodegradable bags available upon request.

Master Carton: 5-layer export-grade corrugated cartons secured with strapping bands to prevent transit damage.

Private Label Support: Full technical pack development, custom swing tags, branded wash care labels, and barcode (UPC/FNSKU) labeling for Amazon FBA or direct warehouse fulfillment.

Frequently Asked Questions

Q: What is the standard sample lead time for custom designs?

A: Physical samples take 7–10 days after technical pack and fabric confirmation. Digital prototypes or color lab dips are provided within 3–5 days.

Q: Are the fabrics certified for harmful substances?

A: Yes. All fabrics are OEKO-TEX Standard 100 certified, with compliance reports issued by accredited labs (e.g., SGS/Intertek), ensuring they are free from restricted chemicals and safe for direct skin contact.

Q: How do you guarantee the leggings are squat-proof?

A: We use high-GSM interlock knit constructions combined with opaque spandex ratios and conduct strict stretch-opacity evaluations during pre-production quality checks.

Q: Can you produce custom colors outside your standard swatch card?

A: Yes. Provide a Pantone TCX code or physical fabric swatch, and our lab will match the shade within a Delta E tolerance of <1.0.

Q: What is your production capacity for bulk orders?

A: Our factory operates 40 seamless knitting lines and 120 assembly stations, yielding a monthly output capacity of 150,000 activewear sets.

Q: What are your accepted payment terms for bulk orders?

A: Standard terms are 30% deposit via T/T upon contract signing, with the remaining 70% balance paid against the copy of the Bill of Lading or after passing final AQL 2.5 inspection.
