Jason Day is a former world number one. He has won a PGA Championship. He has conquered the most difficult courses on the planet. But in 2024 and 2025, people stopped talking about his ball-striking. They started talking about his pants. Specifically, the jason day pebble beach outfit that effectively broke the golf internet.
If you haven't seen it, picture this: one of the most prestigious, historic, and windy golf courses in the world—Pebble Beach. Now, imagine a man walking those fairways in what looks like he just rolled out of bed to grab a breakfast burrito. It wasn't just a choice; it was a statement.
The Groutfit That Shook the Peninsula
Golf fashion is usually a sea of performance-wicking, slim-fit, tech-fabric boredom. Jason Day, in partnership with Malbon Golf, decided to throw that out the window. During the final round of the AT&T Pebble Beach Pro-Am, Day showed up in a full, monochromatic grey sweatsuit.
Fans on social media quickly dubbed it the "groutfit."
The look featured baggy sweatpants—the kind with the elastic ankles—and a matching grey crewneck sweatshirt. No logos except a small, cursive "M" on the chest for Malbon. It was so jarring that CBS commentator Trevor Immelman actually asked on-air if Day had "lost his luggage."
Day, being the veteran he is, leaned into the joke. He later posted to Instagram with the caption: "Lost my luggage. #teammalbon."
But behind the jokes, there was a genuine friction. Pebble Beach has a notoriously strict dress code. Their FAQ explicitly states that guests cannot wear denim, cargo, or—you guessed it—sweats. Yet, here was a major champion playing a sanctioned PGA Tour event in exactly that.

Is It Fashion or a Performance Hack?
Stephen Malbon, the founder of the brand, didn't back down when the traditionalists started clutching their pearls. He pointed out that as a professional athlete, Day prioritizes comfort. When the wind is whipping off the Pacific at 20 miles per hour and the temperature is hovering in the 50s, a heavy-duty sweatsuit actually makes a weird kind of sense.
It’s about layering. It’s about not feeling restricted by tight, modern "athletic" fits.
Why the Baggy Look Matters
- Mobility: Believe it or not, loose fabric can sometimes offer less resistance during a high-speed swing than ultra-tight "second skin" tech gear.
- Heat Retention: Thick cotton blends trap heat better than thin polyester when the marine layer rolls in.
- Brand Identity: Malbon is trying to bridge the gap between streetwear and the fairway. They want kids who wear hoodies to think golf is cool.
Honestly, the "baggy" trend isn't even new. Day himself pointed out that Tiger Woods was wearing oversized, pleated trousers back in the early 2000s. We just forgot because we got used to everyone looking like they were dressed by a computer algorithm for a decade.
The "Banned" Vest and the Masters Fallout
You can't talk about the jason day pebble beach outfit without mentioning what happened at Augusta National. The Pebble Beach sweatsuit was just the sequel.
A few months later, at the 2024 Masters, Day wore a white sweater vest with "Malbon Golf Championship" written across the front in massive, blocky letters. It looked like a billboard. Augusta National—the most "proper" place on earth—wasn't having it.
Midway through the tournament, officials actually approached Day and asked him to remove the vest.

"They asked me to take it off," Day said later. "Respectfully, you do that because it’s all about the tournament here. I understand that."
This created a massive divide in the golf world. On one side, you have the "Green Jackets" who believe the tournament's traditions are sacred. On the other, you have a growing audience that thinks golf needs to get over itself.
Why This Matters for the Average Golfer
So, why does any of this matter to you? Because Jason Day is essentially a crash test dummy for golf's future.
If he can wear sweatpants at Pebble Beach, maybe you can wear a hoodie at your local club without the starter giving you a lecture. The PGA Tour handbook is surprisingly vague, requiring players to present a "neat appearance" and wear clothing "consistent with currently accepted golf fashion."
The problem? Jason Day is the one defining what is currently accepted.
The industry is shifting. We’re seeing more joggers, more hoodies, and more collaborations between golf brands and street labels like Malbon, Metalwood, and even Adidas. Day isn't just trying to be a "rebel"; he has an equity stake in Malbon. He’s invested in making this look stick.

How to Pull Off the Malbon Look (Without Getting Kicked Out)
If you’re inspired by the jason day pebble beach outfit but don't have the "former world #1" status to protect you from the club pro, you have to be smart about it.
- Vary the Fit: If you go baggy on the bottom, keep the top a bit more structured. Day can pull off the "pajama" look because he’s an elite athlete. For the rest of us, it can just look sloppy.
- Texture is Key: Look for "technical" sweats. Many brands now make joggers that look like trousers but feel like sweatpants. They have belt loops, which is often the "loophole" needed for most dress codes.
- Respect the Venue: If you're playing a municipal course, go wild. If you're playing a high-end private club, maybe save the "groutfit" for the 19th hole.
- Confidence is 90% of the Fit: The reason Day didn't look ridiculous to everyone is that he carried himself like he belonged there. He holed out for eagle from a bunker at Pebble while wearing those pants. Success is the best accessory.
Moving Forward: The Future of the Fairway
The reaction to Day's clothes has been, frankly, a bit much. It’s just fabric. But in a sport that has historically used dress codes as a tool for exclusion, a pair of baggy pants becomes a political statement.
Malbon and Day have succeeded in one major way: they made people look. Whether you love the "Lost Luggage" sweatpants or think they belong in a laundry basket, you're thinking about golf fashion.
The era of the "uniform" golfer is ending. We’re entering an age of individuality where comfort and personal style actually matter. It’s about time.
What You Should Do Next
If you want to modernize your own golf wardrobe without causing a scandal, start by looking for lifestyle-crossover pieces. Look for polos with different collars (like the blade or camp collar) or trousers with a slightly relaxed fit. You don't have to go full "groutfit" on day one. Just try one piece that makes you feel more like yourself and less like a walking mannequin. Check out the latest Malbon or Manors collections to see where the trend is heading before your next round.
