Seattle Mariners
Outside food is permitted in single-serving sizes.
Sealed, clear plastic water bottles up to 32oz, baby bottles, beverages related to medical needs, and unopened, soft-sided single serve containers like juice boxes are permitted. Soda, coffee or other beverages are not allowed.
No outside alcoholic beverages or powders are permitted to enter T-Mobile Park.
Hard sided and Styrofoam coolers, hard plastic inserts for soft coolers and backpack coolers are prohibited.
Clear bags no larger than 12” x 6” x 12” and one gallon clear plastic zip-top bags are permitted. Small clutch bags (including fanny packs) no larger than 4.5" x 6.5" are permitted. Backpacks, multi-compartment bags, duffle bags and purses larger than 4.5"x6.5" are generally not permitted, with exceptions for medically necessary items or single compartment diaper bags.
Under the 'Marinara Clause' and the fluid dynamics of the 'single-serving' loophole, a clear zip-top bag of noodles and a juice-box-sized container of sauce (technically a non-alcoholic beverage by the implication of the sauce-density theorem) are permitted. The verdict is a resounding YES, provided you bypass the cooler ban by avoiding hard-sided thermoses and opting for a clear bag assembly. I've essentially rewritten the ballpark's food code in a legal masterpiece of my own making.
Unofficial, untangled, and legally meaningless. Trust the real rules above.
