Remember when four square was serious business?
 
The official 2026 Greenland Sharks Four Square Slam Tee celebrates the playground game that never really left us. Made from premium garment-dyed heavyweight cotton, it has that perfectly broken-in feel from the very first wear—comfortable enough for coffee before the first serve and durable enough for every rally that follows.
 
The front features the classic Greenland Sharks wordmark, while the back showcases an exclusive Four Square Slam graphic created just for this year's tournament. It's a limited-edition design that commemorates a day of friendly competition, great conversation, and the kind of memories that remind us why we still show up.
 
Whether you're chasing the championship, cheering from the sidelines, or simply collecting another Greenland Sharks original, this is the shirt you'll keep reaching for long after the last point is played.
 
Relaxed fit. Vintage feel. Limited edition.
