The football team used nine different football combinations in the 2005 season, but introduced even more combinations in the 2006 season. The new uniforms in 2006 provided 384 possible different combinations of jerseys, pants, helmets, socks, and shoes. A metallic-yellow colored helmet with silver flames, which debuted in the 2006 Las Vegas Bowl, increased the possible combinations to 512. These uniforms were more technologically advanced than other uniforms, 28% lighter when dry, 34% lighter when wet, and greater durability with reinforcing diamond plating patterns at the joints. The Ducks wore the previously announced white helmets for the first time on October 20, 2007 in Seattle, when they played the Washington Huskies. In 2008, during the Arizona–Oregon game, they wore new, all black uniforms nicknamed "lights out", but instead of the typical metal diamond plated shoulder pads, the new uniforms had a wing pattern.
