The 2025-26 Real Betis Third Shirt by hummel features a bold and modern design predominantly in black with striking mint green accents on the collar, shoulders, and sleeve cuffs. A standout feature is the sublimated graphic pattern across the front and lower back, showcasing a mint green tiger-stripe motif that gradually fades into the black base. Constructed with breathable fabric and mesh side panels for ventilation, the jersey includes rubberized 3D silicone applications for the club crest and hummel logo. A unique cultural touch is found inside the collar with the inscribed phrase En la noche quejío y quiebro, drawn from the club's anthem.
