KINGSOO is a professional period underwear manufacturer in China, specializing in OEM/ODM solutions for brands and wholesalers worldwide. Our reusable period underwear combines advanced multi-layer absorbency technology with eco-friendly materials, delivering reliable protection for light to heavy flow. From plus size period underwear to teen-friendly designs, we offer comprehensive customization services including private labeling, pattern printing, and packaging solutions. Partner with a trusted supplier committed to quality, sustainability, and factory-direct pricing.
As a dedicated period underwear factory with over a decade of experience in reusable menstrual products, KINGSOO delivers factory-tested quality that meets international safety standards. Our production facility specializes in creating leak-proof sanitary underwear using certified organic cotton outer layers, moisture-wicking middle fabrics, and TPU-laminated waterproof barriers. Every piece undergoes rigorous absorbency testing and quality control to ensure consistent, retail-ready performance.
We understand how does period underwear work from a manufacturing perspective: our three-layer construction features a GOTS-certified organic cotton top layer for skin comfort, an 80/20 polyester-nylon microterry core that wicks moisture rapidly, and a 100% polyester TPU-laminated inner shield that prevents leaks. This engineering approach allows us to produce non-toxic period underwear without PFAS or harmful chemicals, making our products FSA eligible period underwear that health-conscious retailers demand.
Building your own period underwear brand requires a manufacturing partner who understands both product performance and market positioning. Our custom design services enable you to create distinctive product lines that stand out in competitive markets. We offer complete customization across multiple dimensions to match your brand vision and target demographics.
We manufacture diverse silhouettes including boyshort period underwear, thong period underwear, and high-waist designs suitable for overnight protection. Our absorbency ranges accommodate every need: light-flow styles for daily comfort, medium-absorbency options for regular days, and heavy period underwear engineered to hold up to 30ml of liquid. For specialty markets, we also produce period underwear for sleep with extended gusset coverage and reinforced leak barriers.
Understanding that period underwear plus size options represent significant market demand, we develop size runs from XS through 5XL with graded patterns that maintain proper fit and function across the spectrum. We also specialize in period underwear for girls and teen-focused designs with age-appropriate coverage and playful prints that make the transition to reusable products easier for younger users.
Transform our proven designs into your branded products through comprehensive private labeling services. We offer custom logo printing, embroidered waistband tags, personalized packaging design, and hang tags that communicate your brand story. Our streamlined order process guides you from initial concept through production, sampling, and final delivery, ensuring your vision becomes reality without manufacturing complications.
Today's consumers actively search for period underwear without PFAS and other harmful substances. Our commitment to non-toxic manufacturing means all fabrics undergo third-party testing for harmful chemicals, heavy metals, and endocrine disruptors. We use only PFAS-free period underwear materials, ensuring safety for intimate daily wear. Our organic cotton shells carry GOTS certification, while our TPU laminates meet OEKO-TEX Standard 100 requirements for skin contact safety.
Sustainability drives our manufacturing philosophy. By producing washing period underwear that lasts 2-3 years with proper care, we help brands offer genuine alternatives to disposable products. This longevity answers the common question "how long does period underwear last" with a concrete value proposition: one pair replaces hundreds of pads or tampons, reducing waste while delivering better economics for end users.
Successful period underwear brands educate customers on proper use and maintenance. Our products support this through thoughtful design that simplifies care. For retailers asking how to wash period underwear, we recommend a simple three-step process: cold rinse to remove excess blood, machine wash on gentle cycle with similar colors, and air dry to preserve elasticity and absorbent fibers. This straightforward cleaning period underwear routine maintains performance wash after wash.
Customers frequently ask "do period underwear work" and "can you wear period underwear without a pad?" Our manufacturing standards ensure affirmative answers. Properly engineered period underwear provides standalone protection for most users during light to moderate flow days. For heavy flow period underwear applications, our reinforced gusset designs with extended coverage deliver reliable overnight protection without backup products.
We structure our wholesale programs to support businesses at various growth stages. Our minimum order quantity (MOQ) starts at 300 pieces per style, making it accessible for emerging brands testing new markets. Established retailers benefit from tiered bulk pricing that improves margins as order volume increases. We maintain ready-to-ship inventory of our core styles in neutral colorways, while custom orders typically require 35-45 days from approval to delivery.
Our period underwear serves diverse B2B channels including sustainable fashion retailers, menstrual health e-commerce platforms, subscription box services, wellness boutiques, and institutional buyers like schools or healthcare facilities. We also support white-label partnerships where established brands expand into reusable menstrual products without building in-house manufacturing capabilities.
Beyond period underwear, KINGSOO manufactures complementary reusable products that allow retailers to offer complete sustainable menstrual solutions. Our production capabilities include cloth menstrual pads, period underwear bags for discreet storage, and wet bags for traveling with used items. This product ecosystem helps brands build comprehensive collections that address customer needs throughout their menstrual journey.
International buyers require documented safety compliance. Our facility holds ISO 9001 quality management certification and produces to CE, CPC, and SGS standards. Individual products can be certified to customer-specific requirements including FSA eligible period underwear documentation for US health savings account reimbursement eligibility. We conduct absorbency testing using standardized methods that measure liquid retention, wicking speed, and leak resistance under simulated wear conditions.
Whether you're launching your first sustainable menstrual product line or expanding an existing catalog, KINGSOO provides the manufacturing expertise, material knowledge, and customization flexibility to bring your vision to market. Our team understands both the technical requirements of period underwear production and the marketing narratives that drive consumer adoption in categories like black period underwear for everyday discretion or overnight disposable period underwear alternatives for eco-conscious shoppers.
We invite wholesalers, brand owners, and distributors to explore partnership opportunities. Our experienced export team handles shipping logistics worldwide, provides comprehensive product photography for marketing materials, and offers ongoing technical support as your business grows.
