Dad has the answers. Grandpa has all of them.
This grandpa hoodie carries the Dad Knows a Lot, Grandpas Know Everything crown slogan for the man who taught his kids first and now gets to teach their kids too. It's soft and warm for porch mornings and backyard visits, and it lands well as a present from the whole family.
The design: a crown over three generations
The whole print sits on the chest in clean white. At the top is a five-point crown with a little ball on each tip, a playful nod to the head of the family. Below it, DAD stands in big, heavy capitals with KNOWS A LOT tucked underneath, and a thin rule line separates that first verdict from the bigger one: GRANDPAS in large letters, then KNOW EVERYTHING, finished with a small flourish.
Two silhouettes frame the word DAD. On the left, a father walks hand in hand with a small child. On the right, an older man leans down toward a grandchild who reaches up to hold on. Read together, the figures tell the whole joke without a single extra word: the know-how gets passed down, and by the time it reaches grandpa, there's nothing left he hasn't figured out.
It's the kind of line a family repeats at every holiday table, usually right after grandpa fixes something nobody else could. The back of the hoodie is left plain, so the slogan has the front to itself.
Cozy where it counts
- A 50% cotton, 50% polyester blend that feels soft against the skin
- Midweight 8.0 oz/yd² (271.25 g/m²) fabric, warm enough for cool mornings without feeling bulky
- Soft, smooth yarn that resists the little fuzz balls older sweatshirts tend to collect
- A hood made with two layers of fabric and a matching drawcord, for extra warmth around the head and neck
- Stretchy cuffs and waistband with a little spandex that hug the wrists and hips and spring back after wearing
- A front pouch pocket for warming his hands or carrying reading glasses and a phone
Who it's for
Grandfathers who love being the family's go-to fixer, storyteller and advice line, plus the dads who just stepped up to grandpa. He'll wear it to weekend cookouts, the grandkids' soccer games, fishing trips and lazy Sunday mornings in his favorite chair. Kids and grandkids often give it for Father's Day, Grandparents Day, his birthday or the first visit after a new baby arrives.
Quick answers
How do I pick the right size for him?
It's a men's hoodie. Lay a hoodie he already wears flat, measure it from armpit to armpit and from the top of the shoulder to the hem, then match those numbers to the size guide next to the size options.
Is GRANDPAS KNOW EVERYTHING a misprint?
No. The plural is on purpose: it reads as a rule about all grandfathers, set against the single DAD above it. Every word on the print is spelled correctly.
Is anything printed on the back or sleeves?
No. The back and both sleeves are left blank, which keeps the hoodie easy to layer under a jacket while the slogan stays visible up front.
How should it be washed so the white print stays crisp?
Turn it inside out, machine-wash cold on a gentle cycle with similar colors, then tumble-dry low or hang it up. Skip bleach and dry cleaning, and never iron directly over the print.
