500 LEVEL makes officially licensed, player-first fan apparel with a design for almost every kind of fan: ultra-soft tees, hoodies, and crewnecks in men's, women's, kids', toddler, and infant sizes. This fall, Milwaukee showed why that matters. As Milwaukee clinched their eighth playoff berth in nine years, 500 LEVEL had shirts ready for the players fans were talking about, and Onward's team put those designs in front of the people most likely to wear them.
Key takeaways

Most fan gear starts with a team logo. 500 LEVEL starts with the people and moments fans actually talk about. Its catalog is organized by player, city, and moment, with vintage-inspired graphics, throwback designs, and tees that read like an inside joke only a real fan would get.
The other difference is licensing. 500 LEVEL says every one of its t-shirts is officially licensed by one of the world's premier player associations, including the NFLPA, NBPA, MLBPA, and NHLPA. That is what lets the brand put current players' names on a shirt and keep pace with the season as it happens.
The shirts themselves are a big part of the appeal. 500 LEVEL describes its apparel as ultra-soft, and its premium tees are designed to be worn well beyond game day.
Milwaukee baseball gave fans plenty to rally around this season, and the 500 LEVEL Milwaukee collection now runs to more than 1,200 listings across players, styles, and fits. Three kinds of designs stand out.
The designs pictured at the top of this post are the core of the collection. Jackson Chourio's "Milwaukee Walk Off" tee puts the player and the moment on the front. The Jacob Misiorowski #32 shirsey carries his name and number on the back with a Milwaukee script on the front, so it reads like a jersey at a fraction of the price. A second Misiorowski design pairs his number with a cleaner Milwaukee Baseball wordmark for fans who want something more understated.
The Christian Yelich and Jacob Misiorowski '26 design borrows the look of a campaign sign, pairing a franchise veteran with one of the club's rising arms. It comes on tees and a hoodie, which makes it an easy pick as the weather turns.

Not every fan wants a single player. "Milwaukee Vs. Everybody" is the city-pride tee, with bold gold lettering on blue in two colorways, and it is also offered in kids' sizes. For longtime fans, the collection also includes throwback designs honoring legends like Robin Yount and Paul Molitor.

Yes, and that range is a big part of the brand's appeal. Across the catalog, 500 LEVEL offers these fits and sizes:
Availability varies by design, so check each product page for the fits it comes in. For families heading to the ballpark or watching together at home, that range means everyone can wear the same player, from the grandparents to the newest fan in the house.
Sports demand is sudden. A walk-off, a clinch, or a breakout start can turn a player into the name every fan in a city wants on a shirt overnight, and the window to sell to that excitement is short. Onward runs 500 LEVEL's paid acquisition as a continuous creative-testing engine, timing assets, offers, and urgency to each sports moment so the team can scale up or pull back while the window is still open.
For Milwaukee, that meant pairing new player designs with fresh ad creative and adjusting spend as the season built toward October. The creative keeps the shirt as the hero: the product sits front and center, set against a ballpark backdrop, co-branded with 500 LEVEL and the MLB Players mark so fans know it is the real thing.

Every decision runs on live data. Onward unified more than nine data sources into one view that updates every minute, and optimizes spend toward contribution margin rather than revenue alone, so budget follows the designs and audiences that actually make money.
Milwaukee is the latest example of a pattern Onward has seen before with 500 LEVEL. When a team gets hot, demand for its players' apparel can jump quickly. After the Stanley Cup, 500 LEVEL saw a 10x lift in team apparel revenue, part of the story told in scaling fan apparel into a growth machine.
Across the business, the same profit-first approach has grown year-to-date revenue 156% year over year and new customers from 6,900 to 19,000. The 500 LEVEL DTC growth case study shows how that growth stayed profitable, with every dollar of spend accountable to margin. It is the same model behind Onward's work as an apparel marketing agency for brands that sell across direct-to-consumer and marketplaces.
The holidays are when fan apparel shifts from something people buy for themselves to something they buy for someone else. A 500 LEVEL tee works well as a gift for a few reasons:
Yes. 500 LEVEL says every one of its t-shirts is officially licensed by a player association. Its Milwaukee baseball designs sit within its MLBPA collection.
Yes. The catalog covers baseball, football, basketball, hockey, soccer, college, wrestling, and more, organized by player, team city, and moment.
500 LEVEL gives every fan, from infants to lifelong season ticket holders, a way to wear the players and moments they care about, in shirts soft enough to wear all year.
