- Iki - Backpack
The ultimate backpack packed with Japanese technology
“SUI” was shaped over many years from design to manufacturing, and it fully uses Waprolux leather from Weinheimer, a prestigious German tannery used by the world's top fashion houses.
Furthermore, it is a product truly worthy of the name "SUI," completed with an unwavering commitment to every detail through joint development with artisans who produce for renowned domestic brands, taking as much time as needed and making no compromises.
