Featuring a very outstanding design, the Kappa Betis 20-21 fourth shirt combines a teal base with white sponsor logos an...d white / black trim at the collar that gets repeated at the sleeve cuffs. The striking element is a massive 'K' on the body that is outlined with 1 black and 1 white line. The raglan sleeves are held in the darker shade.
This design is a direct callback to their 96/97 away shirt https://www.footballkitarchive.com/real-betis-1996-97-away-kit/
