This is the official 2024-25 home jersey of Athletic Club Bilbao, manufactured by Puma. The shirt features bold vertical red and white stripes — a classic homage to the club’s iconic identity — with a V-neck collar and short sleeves. Prominently displayed across the chest is the main sponsor 'SIROKO' in black sans-serif lettering with white outline. The club crest, bearing the Basque lion and crown, sits centered above the sponsor. Puma’s black leaping cat logo appears on the right chest, while the left sleeve carries the 'INTER' sleeve patch (likely for Interwetten or a regional partner). A small Puma brand tag is visible at the inner collar, and a LaLiga patch is stitched on the lower left hem. Made from lightweight, breathable polyester with Puma’s dryCELL moisture-wicking technology, it ensures optimal comfort during matches or casual wear. The tailored fit and modern cut blend sport performance with streetwear appeal, making it ideal for fans attending games, training sessions, or everyday casual styling. Perfect for summer and early fall due to its ventilation properties, this jersey embodies Basque pride and contemporary football fashion.
