Our Seamless Antibacterial Briefs address a key consumer demand for hygienic, no-visible-line underwear that performs well under fitted clothing. The seamless construction eliminates bulky side seams and waistband edges, creating a smooth, invisible silhouette under leggings, dresses, and tailored pants. The shell is made from a 95% nylon and 5% spandex blend for four-way stretch and shape retention, while the crotch area uses 100% cotton to support natural hygiene and breathability. The antibacterial feature helps maintain freshness throughout the day, making these briefs particularly suitable for active lifestyles, long work hours, and travel. The one-size fit and six-color range - black, nude, orange, light pink, light green, and gray-purple - offer broad market appeal across age groups and regional preferences.
With 15 years of manufacturing expertise, our 24,000-square-meter factory employs over 1,000 workers and produces up to 600,000 pieces per month. We have supplied major global brands including UNIQLO, and our dedicated R&D team continuously improves seamless knitting techniques and antibacterial fabric treatments. OEM and ODM services are fully supported, with custom sample development completed in 3–7 days. Free samples are available for qualified buyers. Standard orders ship in 7–15 days, custom orders in approximately 30 days. Every production stage is monitored by quality inspection personnel, and finished goods pass through our independent quality inspection center before shipment.
