Rukka is one of the brands belonging to Luhta Sportswear Company, based in Lahti, Finland. Sintra šport, s.r.o. is the official representative of the Rukka brand in Slovakia, the Czech Republic, Hungary and Romania.

In the product development process, Rukka works closely with various research and development institutions to create the perfect product. In active cooperation with suppliers such as Gore and DuPont, new materials are developed and their suitability for functional clothing is tested.

From the planning phase to the final product, Rukka makes no compromises in achieving the best possible results. Each material is tested several times by the supplier and Rukka before being used in production. The production process itself is also subject to constant evaluation. In the final phase of development, professional testers and experienced sports enthusiasts examine the functionality of prototypes in field tests. Findings from countless tests during cold and warm weather, rain and snow are also taken into account before the product is approved for large-scale production.
