Rep your San Francisco 49ers in the field-tested knit hat worn by players and coaches. Made as part of the NFL's Crucial Catch initiative, this is the same design seen on the sidelines, giving fans an authentic connection to their favorite players and a way to support a league-wide cancer awareness effort. Warm, durable, and ready for game day, it's a hat that lets you look the part while backing a cause that matters. The NFL does not profit from the sale of Crucial Catch products. Charitable contributions are awarded by the NFL Foundation to the American Cancer Society.
