MLB Store Online is an online fan-apparel retailer within the “Is That a Hoodie” brand ecosystem, focused on custom-designed hoodies and sweatshirts inspired by Major League Baseball teams. Its products combine casual streetwear styling with team-themed designs, and many options can be personalized with a name and number. The collection covers numerous MLB clubs, including the Boston Red Sox, Chicago Cubs, New York Yankees, Los Angeles Dodgers, and Toronto Blue Jays. The store also lists hoodies for other sports and leagues, including the NFL, NBA, NCAA, NHL, and soccer, as well as wearable blankets.

The brand emphasizes comfort, warmth, and durability, with apparel offered in adult and children’s sizes. Customers can browse best sellers, team collections, and discounted closeout items, including waffle and quarter-zip hoodie styles. MLB Store Online reports worldwide shipping, secure payments, affordable pricing, and 24/7 customer service, and provides order tracking and customer support. It describes itself as powered by fellow fans rather than the official MLB store, and says its distinctive designs are created with design and production partners such as Printful and Dreamship.
