Hongzhao is a direct bag manufacturer in Shenzhen, not a trading company. Led by founder Bowolf Zeng, we work as an OEM and ODM partner for private-label brands and distributors, developing outdoor, sports and functional bags from a tech pack, a reference sample or a sketch.

Each category has its own construction, material options and branding route. Choose OEM from your tech pack or ODM from our base styles, and see how each category is customized.
