Winning Banner 18 wasn't just another notch on the belt for Boston. It was a massive, city-wide sigh of relief after a 16-year drought that felt way longer than it actually was. If you walked through Faneuil Hall or past the Garden in the days following that Game 5 clincher against the Mavericks, you saw it: a literal sea of green. But more specifically, you saw "the shirt."
The official Celtics championship shirt 2024 became the de facto uniform of New England overnight. Honestly, it’s kinda wild how a single piece of cotton can carry that much weight. We’re talking about a design that Jayson Tatum and Jaylen Brown wore while dousing each other in champagne—the same one fans are still hunting for on resale sites today.
What Everyone Actually Wants: The Locker Room Edition
There is a hierarchy here. If you’re a real fan, you know the difference between a "championship tee" and the official Nike Locker Room T-shirt. The latter is the one. It’s the white tee with the Larry O’Brien trophy front and center, flanked by the bold "NBA CHAMPIONS" text.
Nike kept it pretty clean for 2024. No over-the-top neon, just the classic Kelly green accents and the 18-star motif that represents every title since 1957.
- Fabric: 100% Cotton (Standard Nike fit, which runs a bit slim).
- The Vibe: Authentic, sweaty, victory-parade-ready.
- The Rarity: These sold out in minutes on the NBA Store the night of the win.
If you find one now, check the tags. A lot of knockoffs popped up within 48 hours, but the genuine Nike Dri-FIT versions have a specific shimmer to the trophy print that’s hard to fake.
The Caricature Shirt: A Weirdly Big Hit
Fanatics dropped a "Pull Up Jumper" caricature shirt that features the whole starting five. You’ve got Tatum, Brown, Derrick White, Jrue Holiday, and Kristaps Porzingis looking like cartoon legends. It’s goofy. It’s fun. And for some reason, it became the most popular secondary design of the season.
Aaron Dana, a well-known illustrator in the sports world, is often the mastermind behind these stylized looks. Fans love them because they capture the "personality" of the team rather than just the score of the game. It’s the kind of shirt you wear to a summer BBQ to let everyone know you didn’t just watch the Finals—you lived them.

Why 18 > 17 is the Secret Favorite
There’s a specific sub-culture of Celtics merchandise that focuses entirely on the rivalry with the Lakers. Since this win officially put Boston back on top for the most titles in NBA history, the "18 > 17" shirts became an instant hit.
You won't find these at the official TD Garden ProShop usually—they’re more of a "street vendor" or Etsy staple. But they represent the soul of the 2024 championship. It was about reclaiming the throne.
Where to Actually Find One Now
- The Boston ProShop: Located at North Station, this is the mecca. If they’re out of stock online, they sometimes have physical returns or backstock in the actual store.
- Fanatics & NBA Store: The standard. They restock periodically, but by 2026, you're mostly looking at "Legacy" collections.
- Mitchell & Ness: If you want something that feels a bit more "premium," they released a 2024 Champs "Hardwood Classics" style that uses heavier fabric and vintage-wash screen printing.
It’s About the Memories, Not Just the Cotton
Basically, the Celtics championship shirt 2024 isn't just clothing. It's a timestamp. It’s the memory of Jaylen Brown winning Finals MVP and finally silencing the "can they play together?" critics. It’s Al Horford finally getting his ring after 186 playoff games.
When you see someone wearing this shirt in 2026, you don't just see a sports fan. You see someone who remembers exactly where they were when the final buzzer sounded and the confetti started falling from the Garden rafters.

If you are looking to buy one today, prioritize the "Banner Collection" designs. They have a bit more longevity than the "Matchup" shirts that list the Mavericks. You want the one that celebrates the 18th banner, because that’s the historical fact that will matter ten years from now. Check the stitching on the collar—official Nike gear from the 2024 run has a reinforced neckband that holds up way better than the cheap reprints you’ll find on sketchy Instagram ads.
The best way to verify authenticity is the hologram sticker on the tag. If it doesn't have the NBA's official silver holographic seal, it’s a bootleg. Not that there's anything wrong with a "park street" bootleg, but if you're a collector, the hologram is your best friend.
Actionable Next Steps:
- Check the ProShop Physical Store: If you're in Boston, the physical ProShop at TD Garden often carries "Restock" batches of the 2024 championship line that aren't listed on the website.
- Verify the Hologram: Before buying from a third-party seller (eBay, Mercari), always ask for a photo of the silver NBA holographic sticker to ensure you aren't paying premium prices for a low-quality reprint.
- Size Up: The 2024 Nike Championship tees were notorious for shrinking about a half-size after the first wash; if you're between sizes, go larger to keep that "Parade Day" fit.
