For over 16 years, we have built our company on a foundation of trust, innovation, and a deep commitment to empowering every client’s journey from a single sketch to a thriving brand.

What Our Clients Say

“Starting my brand felt overwhelming until I found Sansansun. Their flexible MOQ for private label was a total game-changer, allowing me to launch with a diverse collection without massive risk. The quality of the workout clothes is incredible, and their team made the entire process seamless. We went from concept to live on our store in record time.”

“After dealing with inconsistent quality from other sportswear factories, partnering with Sansansun was a breath of fresh air. Their technical expertise, especially in seamless and bonding technology, is top-tier. Production is reliable, communication is clear, and every shipment of our gym clothing meets our exact specifications. They are a truly professional manufacturing partner.”

“As a designer, I value a manufacturer who can bring ambitious ideas to life. Sansansun’s R&D team is exceptional. They worked with us to develop a custom fabric for our yoga wear line and flawlessly executed our complex designs. Their selection of performance materials and attention to detail are second to none.”

“Building a sustainable brand is our core mission, and Sansansun has been the perfect partner.
