Brand Story
We started Alter Ego to craft hats that aren’t just functional, they mean something. As brothers, we left our corporate careers to chase a vision of premium gear with personality. The Go USA Collection is a nod to the pride we feel seeing athletes represent our country and the unity that sports inspire.
That pride runs deep. Growing up on military bases, raised by the military, we developed a true appreciation for the sacrifices of the men and women in uniform. USA pride is close to our heart, and this collection honors that legacy with designs that stand for performance, resilience, and community. Learn more about our journey in this Alter Ego Brand Story.
