School-day comfy: soft, breathable, tagless feel

What is the origin of Old Daddin’?
Back in 2017, at an ultrasound, Robb (age 40) joked, “What does that make me?” after hearing his wife’s pregnancy called “geriatric.” The tech replied, “You’re an Old Dad.” The name stuck.
In 2024, after a tough stretch, Robb turned that joke into a brand with just a few hundred bucks and a vision. With patches sewn by the neighbor, embroidery by his brother-in-law, and a family-run garage operation, Old Daddin’ was born. Today, it’s more than apparel—it’s a community for dads who wear their status proudly.
