Football wristbands are bands, devices, or bracelets players wear around their wrists during practices or games. They serve multiple purposes, such as managing sweat or providing injury support. These wristbands also contain football play information that players and coaches can reference during a game or practice.

The primary use of football wristbands is communication. They’re essentially cheat sheets for plays and formations – an easy-to-access reference point during a game. It’s not uncommon to see quarterbacks flipping open their wristband to review plays before making that crucial pass or deciding on the next tactical move.
