Planning your trip to T-Mobile Park to watch the Mariners? Understanding the venue's bag policy before you arrive will save you time at the gates and help you avoid the disappointment of leaving items behind. The stadium has clear guidelines about what bags you can bring, along with specific rules for food, beverages, and personal items. Whether you're a season ticket holder or attending your first game, knowing these policies inside and out means less stress and more time enjoying America's favorite pastime.
T Mobile Park Bag Policy: Clear Bags and Clutches
The current T-Mobile Park bag policy requires all bags to be either clear or very small. Specifically, you can bring clear bags measuring up to 12″ x 6″ x 12″ or standard one-gallon clear plastic zip-top bags. The key requirement is that security staff must have an unobstructed view of everything inside your bag from top to bottom.
Anything that blocks visibility into your bag, including non-transparent pouches, interior compartments, or items covering the contents, will result in your bag being denied entry. If you prefer not to carry a clear bag, you have another option: small clutch purses or wallets measuring no more than 4.5″ x 6.5″ are also acceptable, regardless of whether they're clear.

T-Mobile Park Purse Policy: Size Matters
The stadium enforces strict dimensions when it comes to purses and small bags. Any purse exceeding 4.5″ x 6.5″ won't make it through security, so it's worth measuring your bag at home before game day. This compact size is designed to hold your phone, wallet, keys, and other small essentials without compromising security screening efficiency. Consider this an opportunity to travel light, you won't need much once you're inside enjoying the game.
T-Mobile Park Water Bottle Policy
Staying hydrated during a game is important, especially during summer day games. T-Mobile Park allows factory-sealed water bottles that are 20 ounces or smaller. The bottle must be unopened when you arrive at security. If you're bringing kids, you'll be glad to know that juice boxes and soft-sided milk or juice containers are also permitted, as long as they're under 20 ounces. This policy helps families save money while ensuring everyone stays comfortable throughout the game.
Exceptions for Medically Necessary Items and Diaper Bags
While backpacks, multi-pocket bags, duffels, and oversized purses are typically prohibited, T-Mobile Park makes reasonable accommodations for guests with specific needs. If you require medically necessary items or equipment, you can bring an appropriate bag to carry them, just be prepared for additional screening. Parents and caregivers can also bring a single-compartment diaper bag when accompanied by a child. These exceptions recognize that some guests need extra provisions, and stadium staff are trained to handle these situations efficiently while maintaining security standards.
