We maintain long-term partnerships with international brands such as Stanley, Osprey, Musto, Simms, and Hydro Flask, earning a strong reputation through solid craftsmanship and reliable quality.
We have built three factories equipped with advanced high-frequency welding equipment. The sample development and main fabrics are completed domestically, and customers can freely choose factories in China or Vietnam for mass production. The factories in these two places are proficient in both full welding and sewing processes, and the quality is equally excellent. It is worth mentioning that choosing a Vietnamese factory can also help European and American customers save a lot of tariffs, making it more cost-effective.
