In an effort to keep up with security measures at stadiums around the country, Aloha Stadium is beefing up its screening and security standards.

According to KHON2, Aloha Stadium previously did not restrict the number or size of bags brought into the stadium, and large strollers were allowed. Moving forward, however, stadium-goers may each bring one bag into the stadium not exceeding 12” by 6” by 12”.

“Each gate will have a box. If your bag fits in the box, you’re eligible to come inside the stadium,” says Ryan Andrews, deputy manager for Aloha Stadium, the largest outdoor arena in Hawaii.

Stadium visitors are also allowed to carry in a blanket, poncho, jacket and seat cushion, and strollers must fit under the seat.

The changes come before three massive Bruno Mars concerts in November, which are expected to attract 100,000 people spread over three nights.

In addition to these changes, Aloha Stadium will follow inter-league policies by no longer allowing high school football game tailgating.
