what are the colorful nfl hats

The colorful NFL hats are part of the Crucial Catch campaign, which is an initiative to raise funds for cancer research and awareness. During the Crucial Catch gameday, NFL-issued apparel features a rainbow (or multi-colored) logo representing all cancer types. The apparel includes multi-colored equipment for players, including helmet decals, captains patches, wristbands, sideline hats, and quarterback towels, as well as hats and pins for game officials. The Crucial Catch hats and headwear feature bright tie-dye designs worn by coaches and players on the sidelines. The tie-dye designs were introduced to promote the Crucial Catch Program initiated by the American Cancer Society, which helps with the detection and early treatment of cancer. The revenue generated from the sale of these tie-dye designs is forwarded to the American Cancer Society.
