Underdog was born from our dog’s journey.

His start in life was anything but easy. Right after he was born, the future looked uncertain. The beginning gave little reason for hope. But he showed character.

Day by day, he overcame challenges, rose above difficulties, and walked beside us for sixteen years. His circumstances were never easy. But he kept going.

That is where Underdog began.

As golfers, many of us recognize the same feeling. On the course, uncertainty is part of the game. Shots fail, scores fluctuate, and sometimes the whole game feels heavy.

Still, we keep coming back.

Underdog represents resilience without the pressure to be perfect. The willingness to keep moving forward, even when things do not go as planned. To be kind to yourself — yet never give up.

Our dog taught us that the journey does not always follow the straightest path. But it can still be meaningful and worthwhile.

That same idea lives within Underdog.

This is for those who keep going. Round after round. Season after season.

For golfers who understand that the real question is not always about winning — but about refusing to quit.

Built for the long game.

Meet the Founder
ARI TULONEN — Creative Director & Founder

Golf has always been more than a game to me — it’s a mindset. Every round teaches patience, focus, and the courage to keep going when things don’t go as planned.

That same spirit is what built Underdog. It’s not about chasing perfection, but about embracing resilience and staying true to the long game.

I’m Ari, the founder of Underdog. This brand was born on the fairway — from a desire to create something real, something that reflects the quiet determination behind every swing.
