Absolutely love my shirt and hat! I get so many compliments on them. Best of all is the order process and customer service is second to none, they made feel like part of the Old Daddin family rather than just another customer.....keep up the great work, and everyone support this awesome group!
Heck yes, Happy Old Dad! You’re officially part of the family now—no awkward initiation ceremony required (unless you count dad jokes and coffee mugs you didn’t ask for). Thanks for reppin’ the gear and spreading the Old Daddin’ gospel. We’ll keep doing the work if you keep being awesome. PS: Compliments are basically our currency—spend ‘em freely! 🔥💪
I saw them on IG and loved how the hats looked. I got a big head so I don’t usually grab snapbacks and I mentioned that in the comments. Later on they DM’ed me to let me know they were just about to release XL’s. Needless to say I purchased and am extremely happy with the hat and how it looks on my giant head. Top of the line customer service as well. I’ll definitely be back for more stuff for myself as well has gifts for homies and family.
Having kids later in life wasn't my first choice but now I wouldn't change it for the world. Being 36 and having another kid on the way makes me realize Old Dads are the best. So I'm embracing the Old Dad life and joining the Old Daddin' Club!!!The OG hat has an incredible fit and beautiful style. They really knocked it out of the park with this one!!!

Mag-nificent little touch!Wasn’t exactly sure where I’d put my magnet, but found a great place in my old truck! Very cool touch!
Perfect Birthday GiftWhen my husband goes out with our 3.5YO, people stop them and ask her, "Are you out with Grandpa today?" She's been sassily correcting them that he's Daddy, not Grandpa. The mug in my husband's favorite color of hugger orange was a great birthday gift for him. It is a stand out way for him to declare his Old Dad awesomeness. And that he's not Grandpa.

FAQ's
How do I know if I'm an Old Dad?
If you’re an older dad who’s been there, done that, and wear your dad status with pride—Old Daddin’ is for you. It started as a joke, but now it’s a badge of honor. From hats and T-shirts to hoodies and mugs, our gear is all about celebrating fatherhood at any age. Wear it loud, wear it proud—because being an Old Dad is something to celebrate.
How do I choose the right hat size?
Most of our hats are designed with adjustable straps for a one-size-fits-most fit. If a product has specific sizing details, you’ll find them in the description. For those of you Old Dads with a giant head, don’t worry—we’ve got you covered. We offer XL versions in four best-sellers: The BRAD, The TY, The ROBB, and The HARRISON.
How are the products made?
Every Old Daddin’ piece is built for comfort, durability, and a touch of humor. All patches are hand-stitched one by one by our neighbor—affectionately known as The Patch Man—and our circle-logo embroidered hats are stitched by our brother-in-law in his basement shop. Family-powered, local, and made with pride.
What is your shipping policy?
We ship fast: hats, mugs, keychains, and magnets head out within 24 hours; everything else ships within 2–3 business days. Delivery times vary by location, but you’ll always receive tracking once your order is on the way. Shipping rates are calculated at checkout so there are no surprises.
How do returns and exchanges work?

In that rare case, contact us within 7 days and we’ll replace or refund. Please double-check your shipping info—we can’t replace orders sent to the wrong address.
How should I care for my products?
For apparel: wash inside-out in cold water, tumble dry on low. For hats and accessories: spot clean with mild soap and air-dry. Treat them well, and they’ll stick with you for the long haul.
Do you offer custom designs?
Not right now, but never say never. We’re always brainstorming new drops and love hearing your ideas. Got something in mind? Reach out—we might just make it part of the Old Daddin’ lineup.
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.
