There are many options for purchasing official League of Legends merch, including shirts and hoodies. If you'd prefer to avoid paying for an item created by Riot Games, you can also find unofficial League of Legends merchandise on sites such as Etsy. Etsy is full of individual sellers and small businesses selling League of Legends-related items. Although these options may not be the most convenient, they will at least give you the option of purchasing items made by people who love the game.
