Oregon Fish and Wildlife Commission voted in 2010 to make it mandatory that youth hunters wear hunter orange. This goes into effect August 1st. Youths 17 and under must wear the bright orange known as hunter orange, except during archery season or when hunting wild turkey or migratory birds. They can wear a hat with the orange color, or camo with the orange in it.
Some limited youth elk, bear, and cougar season open on August 1st, but most seasons open in September and October. From The Statesmen Journal .
