Going to an NFL game this fall? Leave everything at home.

Especially if you’re a woman. That’s the upshot of the NFL’s new security policy, which will restrict the size and types of bags that fans will be permitted to bring into stadiums. The new policy, which is effective with preseason games, was unanimously recommended by the NFL’s Committee on Stadium Security.

“Our fans deserve to be in a safe and secure environment,”Jeffrey Miller, the NFL’s vice-president and chief security officer, told NFL.com. “Public safety is our top priority. This will make the job of checking items much more efficient and effective. We will be able to deliver a better and quicker experience at the gates and also provide a safer environment. We appreciate our fans’ cooperation.”

Here’s what is allowed:

Only clear plastic, vinyl or PVC bags no larger than 12 inches by 6 inches by 12 inches;

One-gallon clear plastic freezer bags;

Small clear plastic bags roughly the size of a hand and with or without a strap or handle.

Each fan will be allowed one of those clear bags and a small clutch bag roughly the size of a hand.

Binoculars, cameras, and smartphones will be permitted.

It’s a policy that isn’t going to be terribly popular with women because “prohibited items include, but are not limited to: purses larger than a clutch bag, coolers, briefcases, backpacks, fanny packs, cinch bags, seat cushions, luggage of any kind, computer bags and camera bags or any bag larger than the permissible size,” the league said in a statement.

The NFL increased security at the draft in April, roughly two weeks after the Boston Marathon bombing, but said this move was unrelated.

“We had been discussing a new approach to bag restrictions before the Boston Marathon incident,” the league’s statement said. “We have come up with a way to do it that will actually make access more convenient for fans than it has been. We think the fans will embrace and appreciate it.”
