T-Mobile Park
Seattle, WA · Stadium
T-Mobile Park runs a clear bag policy, so plan on either a clear bag or a very small clutch. A clear plastic bag up to 12 by 6 by 12 inches gets in, and so does a one-gallon clear zip-top bag, with security needing to see all the way to the bottom. The one non-clear option is a small clutch no bigger than 4.5 by 6.5 inches. Backpacks, multi-compartment bags, duffle bags, and purses larger than that clutch are all turned away. Medically necessary items and single-compartment diaper bags with a child present are the exceptions and get inspected at the gate. The Seattle ballpark applies this to Mariners games and to its concerts, though a tour can tighten it, so check your event page before you head to SoDo. Show up with a clear 12 by 6 by 12 bag or a 4.5 by 6.5 clutch and you will move right through.

No bag that fits? Plan ahead
T-Mobile Park does not advertise general bag storage, so a backpack or oversized bag should stay in your vehicle. The Mariners publish a guest services line for bag questions, and arriving with a compliant bag is the smoother play.
Common questions
Does T-Mobile Park require a clear bag?
Yes for anything larger than a small clutch. A clear bag up to 12 by 6 by 12 inches gets in, and the only non-clear option is a clutch no bigger than 4.5 by 6.5 inches.
Can I bring a backpack to a T-Mobile Park concert?
No. Backpacks, multi-compartment bags, duffle bags, and purses larger than the clutch size are all prohibited. Bring a clear bag or a small clutch instead.
Are diaper bags or medical items allowed?
Yes. Medically necessary items and single-compartment diaper bags with a child present are allowed and inspected at the gate.
Is the bag policy different for concerts than for Mariners games?
The clear bag rule is the same for both, though a tour can tighten it for a specific concert. Check your event page before you go.
