Crafted by Castore, the shirt is engineered with lightweight, breathable fabric to help keep you cool and comfortable whether you're in the stands, on the pitch, or representing Boro around town. A subtle tonal lion graphic pattern adds depth to the design, while the special Middlesbrough FC 150 Years crest sits proudly at the heart of the shirt, celebrating a century and a half of club history.

Finished with Castore branding and sponsor detailing, the Third Shirt is a bold addition to any Boro supporter's collection.
