An inflatable tunnel or air-inflated tunnel is a tunnel that is inflated by an external cold air inflation fan connected to the tunnel via an inflation tube. Inflatable tunnels are customarily 10' to 30' long when inflated and often attached to inflatable helmets, mascots or team logos.
Inflatable tunnels are typically used by professional, college and high school sports teams and first started appearing in the 1980s. One of the first inflatable team tunnels was used by the San Diego Chargers in 1994. Most NFL teams use an inflatable tunnel for player introductions.
