Girls Flag Football for Ages 8-14

This 5 on 5 program, known as Girls Flag 5s, is the same sport that will be introduced in the Olympics in 2028. Girls learn the fundamentals of football in one of the most exciting developments since Optimist Youth Football was born in the Treasure Valley more than 75 years ago.

This league is about more than competition. It’s about teamwork, confidence, and skills that empower young athletes to shine on and off the football field.
