What are rules covering what fans can bring into the stadium during games.?

Can bring water as long as it isn't opened

All current information is on Yankees website

Sunscreen in a plastic tube only...no metal or spray can

Best bet is always to either call or check their website

Also have to be in a clear bag

According to their website: Food And Beverage Policy Guests are permitted to bring food into Yankee Stadium for individual consumption. Items such as apples and oranges must be sliced or sectioned. Clear factory-sealed plastic bottles of water, 1 liter in size or smaller, are also permitted.

I was told nothing bigger than a six pack cooler and of course no weapons
