L&J Down
“Delivering Warmth, Where You Can’t See It”
The Company
L&J Down is a leading supplier of high-quality duck and goose down for the global market, founded on May 2, 2018 in Seoul, South Korea. With our headquarters in Seoul and branch offices in Nanjing and Hong Kong, we’ve built a reliable supply chain backed by over 20 years of industry experience and a deep commitment to trust. Our main business focuses on washed down for apparel and bedding products. With a dedicated team of six specialists, we deliver customer-centered service tailored to the unique needs of each partner.
Guided by our vision — “Delivering warmth where you can’t see it” — we strive to bring genuine comfort into everyday life. We go beyond simple transactions, aiming to build long-term partnerships through ethical and sustainable down sourcing, always delivering products that combine quality and value for consumers around the world.
What makes us different?
At L&J Down, we create distinct value built on quality, trust, and competitiveness.
Our strict quality control system is what sets us apart. We conduct a two-step inspection process: 1. An initial inspection at our partner factories in China, focusing on blend ratio, fill power, and odor 2. A secondary verification in our independent testing lab in Nanjing, minimizing quality variance and ensuring excellence. When needed, we also provide third-party certifications to add objective credibility.
In addition, our stable supply chain is a major strength. We maintain strong partnerships with carefully selected factories across China, securing a consistent supply of high-quality raw materials.
Above all, we prioritize customized service. We listen closely to each customer’s quality standards, volume requirements, and deadlines — offering flexible adjustments and prompt responses to maximize satisfaction.
Mission & Values
Trust and warmth — they’re at the heart of everything we do.
At L&J Down, we believe in delivering warmth where it can't be seen — not just in the products we offer, but in the relationships we build.
The down we provide is more than just filling material; it’s a symbol of the trust we share with our clients.
We bring rigorous quality control and a deep sense of ethical responsibility to every product. Even the invisible details are crafted with honesty and care.
Through ethical, sustainable practices, we go beyond simple business — building long-term partnerships and bringing warmth to everyday life for customers around the world.
