They came up with the idea of designing a tee shirt and selling it on the street. At that time they did not know it, but this would turn out to be their first tee shirt collection especially made for the fiestas. Many years have passed since then but their spirit remains the same. The tee shirts continue to cover the drinking costs and just as Sanfermin has its poster, its opening txupinazo rocket and its award-winning bull, so too does it have its special Kukuxumusu tee shirt each year.
Over the years Kukuxumusu has invented the blue bull with yellow horns who passed through the streets displaying its private parts and who even played football, or even found itself being chased by runners in a reverse reproduction of the running of the bulls.
The collection issued each year now includes jerseys, polo shirts, jackets, fans, key-rings or caps and such and they can found at any of the outlets that Kukuxumusu keeps open during the fiestas, for example in their places in Estafeta street. They also have an Online Shop and their own chain of official stores and there you will also find a small corner dedicated to the Sanfermin gear.
