Because I'm Yah Fathah That's Why T-Shirt
Product Description
Because I’m yah fathah, that’s why. The Because I’m Yah Fathah That’s Why t-shirt is the warm-weather dad-authority flex for the Boston dad whose reasoning is final, who treats the phrase as a one-line household constitution, and who’d argue the line ends more arguments than logic ever could. Bold no-nonsense lettering on charcoal, soft cotton blend.
Available in classic men’s tee and long sleeve cuts. Light enough for July cookouts, soft enough for the deck chair after — he’ll wear it through every backyard hang and every long Saturday when somebody’s gotta be the bad guy.
