Nestled in your season ticket package is the 2017 scarf, a book introducing you to your Alliance membership and other Seattle Sounders gameday events, and a clear plastic bag with a large Sounders logo on it. That bag is now part of your gameday experience.
This policy was already in place for Copa America Centenario, Seahawks games and other stadium events.
You will still be subject to the metal detectors and search prior to entry to CenturyLink Field. You will no longer be able to carry just any 12” by 12” by 6” bag.
