Of all 32 teams for whom Nike is developing uniforms, the Seattle Seahawks pushed the design elements more than most. It incorporates cultural elements of the Northwest, including horizontal graphics representing the thunderbird totem and colors inspired by the region's environment. On the pants, 12 winged icons down the side reference the 12th man, a tribute to the team's fans. Some teams incorporated all of Nike’s suggestions; others chose minor updates. The NFL line for consumers will be available at the end of April.
