Sisu Running Cap
Choosing to run Dirty 30, one of the toughest 50k’s in the country as your first ultra deserves special recognition. Those who finish the Dirty 30 as their first ultra-running race are inducted into the Sisu Club. Sisu is a Finnish word meaning grit, determination, perseverance, and intestinal fortitude. It takes all this to finish the Dirty 30.
This cap has a velcro size adjuster. Sisu printed across the front, Intestinal Fortitude printed on the bill, and the Dirty 30 logo on the left side. This cap is lightweight and vented on the top.
