For producing Model K212 we use high quality materials listed below;
Upper Leather: Cow Suede Leather (high quality cow leather). It has privileges against other types of leathers such as:  not loosing the form, color and it has better water repellency.
Upper Textile: As a fabric we use Nylon 6.6 Cordura®  by Invista 1000 DEN. directly from manufacturer. This gives us the authorization to use Brand name Cordura®. The high quality is guaranteed as Cordura® is a high-quality fabric woven with polyamide fibers. This material is very light and breathable. Thanks to its extreme tear and abrasion resistance, Cordura® is very suitable to be an upper material. In addition, it is dirt- and water-resistant and dries quickly.
