San Francisco's longest continuously operating company, Boudin Bakery, makes one of its most iconic foods: sourdough bread. Even the 49ers mascot is named Sourdough Sam.

The designs feature the San Francisco 49ers logo and other images representing the city and team. A more generic version of the swim trunks is also available for a cleaner, more official look.
