The 2025-26 Rayo Vallecano Home Shirt by Umbro maintains the club's iconic identity with a clean white base featuring the striking red lightning bolt across the front. This season's design introduces vibrant yellow accents that outline the lightning bolt and detail the collar and cuffs, adding a fresh and energetic look to the traditional kit. The Umbro double diamond and sponsor logos are rendered in black, providing a sharp contrast against the white and red background. This jersey combines modern technical materials with a classic aesthetic, celebrating the deep connection between the club, the Vallecas neighborhood, and its passionate supporters.
