This is the official 2023–24 third football jersey of AS Saint-Étienne, manufactured by Hummel. The shirt features a bold geometric pattern in varying shades of green (from forest to mint), creating a dynamic diagonal grid effect across the front and sleeves. Prominently displayed in white sans-serif typography is the sponsor slogan '—SMART GOOD—THINGS', positioned centrally below the club crest and departmental logo 'Loire LE DÉPARTEMENT'. The Hummel bee logo appears on the right chest, while the ASSE crest sits on the left. The collar is black with white piping, and the shoulders feature Hummel’s signature white chevron stripes. Short sleeves end with white trim, enhancing contrast. Made from lightweight, breathable polyester performance fabric, it offers moisture-wicking properties ideal for matchday or casual streetwear. The design merges contemporary street aesthetic with traditional football heritage, making it suitable for fans, collectors, and fashion-forward sportswear enthusiasts. Ideal for summer wear due to its ventilation and vibrant colorway.
