Since 2001, we have focused on the research, development, and production of seamless underwear, serving clothing brands, startups, and sourcing companies worldwide. Our seamless bras are engineered for comfort, fit, and performance, with a strong emphasis on sustainable materials and traceable supply chains.
We supply a complete range of seamless bras, including everyday bamboo viscose bras, sports and running bras, racerback sports bras, and spaghetti strap camisoles. Each product is designed to meet the demands of modern consumers who expect invisible lines, breathability, and durability. Whether you need a custom design, private label, or bulk production, our factory provides end-to-end support from fabric selection to final packaging.
Our Product Range
Bamboo Viscose Everyday Bras
Ideal for daily wear, offering a smooth, gentle feel against the skin. The seamless construction conforms to the body, allowing free movement without restriction. Safe, eco-friendly, and perfect for reducing visible lines under clothing.
Sports & Running Bras
Designed for active lifestyles, these bras provide medium to high impact support. They feature moisture-wicking fabrics, breathable mesh zones, and compression or encapsulation designs to minimize bounce during running, HIIT, or gym workouts.
Racerback Sports Bras
A versatile style that offers a full range of motion, making it suitable for yoga, Pilates, and everyday wear. The racerback design distributes weight evenly across the shoulders, reducing strain during movement.
Spaghetti Straps Camisoles
Lightweight and stylish, these camisoles work as loungewear or as a layering piece. They provide light support with a seamless finish, ideal for casual or sleepwear collections.
Application Fit & Material Considerations
Seamless bras are engineered to eliminate seams that cause chafing and visible lines. We use high-performance yarns such as bamboo viscose, recycled nylon, recycled polyester, and spandex blends. Bamboo viscose is naturally soft, breathable, and moisture-absorbing, making it ideal for sensitive skin. For sports applications, we incorporate moisture-wicking and quick-dry properties to keep the skin dry during intense activity.
When selecting materials, we consider the intended use: everyday bras prioritize softness and comfort, while sports bras require higher elasticity and support. Our R&D team continuously tests fabric blends to optimize stretch recovery, durability, and colorfastness, ensuring that the final product meets your brand's quality standards.
Critical Specifications & Performance
Our seamless bras are produced with precise knitting technology that creates a single-piece construction, eliminating side seams and underarm bulges. Key specifications we control include:
- Fabric weight: Typically 160-220 gsm depending on style and support level.
- Elasticity: Spandex content ranges from 10% to 20% to ensure a snug yet comfortable fit.
- Moisture management: Treated with wicking finishes for sports styles.
- Breathability: Mesh panels or perforated zones in high-sweat areas.
- Dimensional stability: Tested for shrinkage and stretch recovery after repeated washing.
We also offer a range of customization options, including different cup shapes, padding (removable or fixed), underwire or wire-free, and adjustable straps. Our factory can accommodate sizes from XS to XXL, with grading rules based on your target market.

Quality Assurance & Acceptance Testing
Every order undergoes rigorous quality control at multiple stages: incoming material inspection, in-line production checks, and final random sampling. We test for fabric integrity, colorfastness, shrinkage, and stitching strength. For sports bras, we also evaluate support and elasticity to ensure they meet performance expectations.
Before shipment, we can provide pre-shipment inspection reports or arrange third-party inspections as required. Our goal is to deliver products that meet your specifications and pass your own quality checks.
