This project is an internal R&D initiative by KALTE STUDIO, exploring the synergy between two iconic design codes: the premium classicism of Louis Vuitton and the sporting heritage of Lacoste. As part of this tennis case concept, we merged the durability of leather with the distinctive texture of a tennis ball, creating a unified product that reimagines traditional sports equipment as a high-design object. The primary focus was placed on material detailing — from complex monogram embossing to the tactile fuzz of the textile.
