The Middlesbrough FC Third Jersey 2026-27 introduces a bold electric yellow and navy colour combination for Boro's new season.

Designed by Castore, the 2026/27 Third Shirt combines a vibrant yellow base with contrasting navy details and a subtle tonal lion graphic inspired by Middlesbrough's new crest.

The result is a modern alternative football shirt that combines Boro's new visual identity with a striking high-contrast colour palette.

Middlesbrough FC Third Jersey 2026/27

The Middlesbrough FC Third Jersey 2026/27 is the club's official third-choice shirt for the new season.

Unlike the traditional red Home Shirt and the predominantly white Away Shirt, the Third Jersey uses a vibrant electric yellow as its dominant colour.

Navy detailing provides contrast throughout the design, while a subtle sublimated lion graphic adds a distinctive connection to Middlesbrough's new club crest.

Castore Middlesbrough Third Shirt

The 2026/27 Middlesbrough FC Third Shirt is produced by Castore.

Castore continues as Middlesbrough's official technical kit partner for the 2026/27 campaign, creating the club's new Home, Away and Third collections.

The Castore branding appears alongside the new Middlesbrough FC crest, giving the shirt a contemporary professional football appearance.

Electric Yellow Middlesbrough Football Jersey

The defining colour of the 2026/27 Third Jersey is electric yellow.

The bright yellow base gives the shirt a powerful and energetic appearance, making it visually different from Middlesbrough's traditional red home colours.

The electric yellow body is balanced by navy blue details, creating a clean two-colour football aesthetic.

Middlesbrough Yellow Navy Third Jersey

The combination of yellow and navy is the central visual identity of the Third Kit.

The yellow base provides the dominant colour across the shirt, while navy elements add contrast around the key design and branding areas.

This colour combination gives the jersey a modern appearance while remaining clearly connected to Middlesbrough FC through its crest and club branding.

Middlesbrough Lion Graphic Jersey

One of the most distinctive elements of the 2026/27 Third Jersey is the subtle lion graphic.

The lion is incorporated into the shirt as a tonal sublimated pattern, creating a textured visual effect without overpowering the main yellow-and-navy colour scheme.

The graphic is inspired by the lion featured in Middlesbrough's new crest, introduced for the club's 150th-anniversary season.

Middlesbrough New Crest Jersey 2026/27

The 2026/27 season marks an important visual change for Middlesbrough FC.

The club introduced a new roundel-style crest for the 2026/27 season as part of its 150th anniversary celebrations, and the new Third Jersey incorporates the lion imagery associated with this updated identity.

This makes the 2026/27 Third Shirt particularly relevant for supporters collecting Boro's new-era merchandise.

Middlesbrough FC 150th Anniversary Season

The 2026/27 season represents Middlesbrough FC's 150th anniversary.

The club's new visual identity and new crest are part of the celebrations surrounding this milestone season.

While the Third Jersey is a standard matchday kit rather than the dedicated anniversary shirt, the subtle lion design connects it with the club's new 150th-anniversary era.

Castore Middlesbrough Football Shirt

Castore's design gives the 2026/27 Third Shirt a modern football silhouette.

The strong yellow base allows the navy details and tonal lion graphic to stand out, while the overall design remains clean enough for everyday football-streetwear styling.

It works naturally as a matchday shirt, supporter jersey or football fashion piece.

Middlesbrough FC Third Kit 2026/27

The Third Jersey completes Middlesbrough FC's standard 2026/27 matchday collection.

The three main designs create clearly different identities:

• Home: Traditional Middlesbrough red with gold detailing
• Away: White with blue and polka-dot inspired detailing
• Third: Electric yellow with navy details and a tonal lion graphic

The Third Kit therefore provides the most vibrant colour option within the standard 2026/27 collection.
