Fans attending home football games at Martin Stadium this season will have to use a clear bag for their belongings due to a new athletics policy.

The new policy states bags must be clear PVC, vinyl or plastic and cannot exceed a certain size, according to a WSU Athletics press release.

Other appropriate bags include one-gallon freezer bags, clear drawstring bags and small clutch bags. The policy comes in an effort to increase safety, Director of Athletics Patrick Chun said in a release.

“The addition of this policy is another effort to enhance the gameday environment and provide the safest experience possible at Martin Stadium,” he said in the release. “This is in line with best practices throughout the country.”

Exceptions may be made in the case of necessary medical items that have gone through an inspection, according to the press release.

The policy also means some items, including purses and bags larger than a clutch, backpacks, cinch bags, coolers, luggage, camera bags, fanny packs and any other large bags, will not be allowed within the venue, according to the press release.

Fans will still be allowed to carry personal items like keys, wallets, cell phone and other thing, according to the release. The first 10,000 fans at the home opener on Sept. 8 against San Jose State University will receive approved clear bags.
