The team, ranked No. 2, is also sporting pink Nike Vapor Talon Elite cleats, pink Nike Vapor Carbon Elite socks and pink Vapor Jet gloves in combination with their black Nike Pro Combat uniform system.
On goducks.com, the team writes, "The pink helmets worn by the Oregon Ducks pay tribute to those who have been affected by women's cancers."
Starting October 19, five helmets a day will be auctioned off for five days. Each helmet will open at $14, and the proceeds will go to "aid in the fight against women's cancers."
The Ducks take on the Washington State Cougars on Saturday.
