Lumen Field, home of the Seattle Seahawks and Seattle Sounders FC, enforces a clear bag policy designed to balance fan safety with faster entry processing.
Before you attend any match or FIFA World Cup 2026 event at the stadium, knowing exactly what bags are permitted will save you time, confusion, and disappointment at the gates.
This guide covers the specific rules, exceptions, and practical tips for preparing your bag for your visit.
Lumen Field Bag Policy Compliance Chart
| Bag Type | Size Limit | Material | Status | Notes |
| Clear tote bag | 12″ × 6″ × 12″ | Plastic, vinyl, PVC | ✓ Allowed | Most common choice |
| One-gallon freezer bag | Up to 1 gallon | Clear plastic | ✓ Allowed | Ziploc or similar |
| Clear backpack | 12″ × 6″ × 12″ | Plastic, vinyl, PVC | ✓ Allowed | Max 2 pockets only |
| Small clutch | 4.5″ × 6.5″ | Any material | ✓ Allowed | Bring with clear bag |
| Diaper bag (clear) | 12″ × 6″ × 12″ | Plastic, vinyl, PVC | ✓ Allowed | Subject to inspection |
| Medical bag | Per inspection | Any material | ✓ Allowed | Medical necessity gate |
| Non-clear backpack | Any size | Any material | ✗ Prohibited | Rejected at security |
| Opaque handbag | Over 4.5″ × 6.5″ | Any material | ✗ Prohibited | Use bag check service |
Clear Bag Policy Requirements
You must use clear plastic, vinyl, or PVC bags not exceeding 12 inches by 6 inches by 12 inches.
These dimensions give you enough space for phones, wallets, small cameras, and light snacks, while the transparency requirement lets security staff visually inspect contents without extensive searching.
You can also bring clear backpacks if they stay within the 12″ × 6″ × 12″ limit and have no more than 2 pockets.
Vinyl and PVC create the same transparent effect as plastic while offering more durability. Many attendees mistakenly believe only plastic works, but all three materials pass inspection.
One-gallon freezer bags (Ziploc style bags) offer another option if you prefer a smaller, more portable container. These bags cost less than $1, are disposable, and work perfectly for essentials.
Many fans choose freezer bags as their primary option specifically because they eliminate any concerns about being turned away for non-compliance. Per NFL’s All Clear policy, all NFL venues including Lumen Field enforce these standards uniformly.
Allowed Bag Materials & Types
The material science behind this policy matters more than you might think. Clear plastic is petroleum-based and creates the highest transparency. Vinyl is typically PVC with added plasticizers for flexibility.
PVC (polyvinyl chloride) is a rigid plastic that becomes flexible when modified. All three materials achieve the same transparency that makes contents immediately visible to security staff.

Size Limits: 12″ × 6″ × 12″ Full Clear Bag
You must keep your clear bag within 12 inches by 6 inches by 12 inches. This is the maximum dimension for full-size clear bags at Lumen Field, following NFL security standards adopted across the league and reinforced for international events like the World Cup.
You need to measure correctly to prevent rejection. Many attendees eyeball dimensions and arrive with bags that look small but exceed specifications.
How to Measure Your Bag Correctly
Use a flexible tape measure or ruler and measure your bag when it’s empty and laid flat. Measure the length (longest side), width, and height at their widest points. For bags with curved bottoms or flexible sides, measure when the bag has nothing in it and isn’t compressed.
Your bag is acceptable if it measures exactly 12″ × 6″ × 12″ at the limit. If any dimension exceeds these numbers, you need a smaller option. Round up when measuring. If your width measures 6.1 inches, you’re technically over the limit.
For comparison, a standard shoebox is typically 13″ × 8″ × 5″, so the clear bag allowance is smaller than a shoebox in most directions. This size limit fits a wallet, phone, small camera, water bottle, and light snacks, but not a full day’s worth of items for longer matches or events.
What Fits in This Size? (Example Items)
You can realistically fit several essentials in a 12″ × 6″ × 12″ clear bag:
| Item | Fits Easily |
| Smartphone | Yes |
| Wallet | Yes |
| Small digital camera | Yes |
| Sunglasses | Yes |
| Sunscreen | Yes |
| Light jacket | Yes |
| One-liter water bottle | Yes |
| Tablet | No |
| Laptop | No |
| Book | No |
This size works perfectly for match day when you’re not bringing much beyond tickets and essentials. Most people use this clear bag for two to three hours at the stadium and leave everything else in their vehicle or hotel.
You need this dimension because it creates the fastest screening times. Staff can visually inspect a small clear bag in seconds, moving the queue rapidly.
Per NFL security documentation, the 12″ × 6″ × 12″ standard reduces average entry screening time by 40% compared to larger bag options.
The Small Clutch Exception (4.5″ × 6.5″)
You can bring one non-clear bag measuring 4.5″ × 6.5″ or smaller, along with your clear bag. This exception exists for practical reasons: wristlets, small wallets, and handheld purses don’t require transparency if they’re small enough that prohibited items can’t fit inside.
This exception bridges the gap between security requirements and personal preference. You can carry a designer clutch instead of a clear bag if you prefer. You can use a small leather wristlet over transparent plastic. The constraint is size, not material.
Common Clutch Types That Work
You can bring designer wristlets from brands like Coach, Tory Burch, or Fossil if they measure under 4.5″ × 6.5″. These clutch styles typically meet requirements:
- Small leather pouches sized for credit cards and cash
- iPhone-sized clutches designed specifically for phones and IDs
- Wristlets with single zippered compartments
- Hand-held wallets with card slots only
- Mini crossbody bags less than 5″ wide
You need to size-check crossbody bags marketed as “mini” before you arrive, even though they feel small when worn. Their actual dimensions might be 6″ × 7″, which gets rejected.
You should only bring bags that genuinely fit essentials: phone, ID, cards, keys. If a bag comfortably holds your full wallet, large sunglasses, and a snack pack, it’s too large for the clutch category.
Medical & Diaper Bag Exemptions
Lumen Field permits exceptions to the clear bag policy for medical necessity and infant care. You can bring equipment or supplies that require additional space and cannot fit into standard bags.
Caregivers traveling with infants should know that you can bring diaper bags as long as you submit them for inspection at designated gates.
The inspection process adds 5-10 minutes to your entry time, but the bag gets tagged and permitted. It’s not a rejection; it’s additional screening to ensure compliance with prohibited items lists.
Medical Bags (Medications, Supplies, Assistive Devices)
You can bring medications, insulin pumps, EpiPens, inhalers, and other medical devices beyond the standard clear bag limits.
You don’t need to hide these in a transparent bag. Instead, enter at the medical/accessibility gate where security personnel can visually inspect the bag and its contents, then tag it for entry.
You should bring identification or documentation of medical need if possible. While Lumen Field doesn’t require prescriptions or doctors’ notes, having them prevents confusion at the gates. Label medications clearly and explain any unusual-looking medical devices.
Mobility aids like canes, walkers, or crutches are separate from the bag policy and permitted without restrictions.
According to Lucas Oil Stadium’s medical exemption policy, most major venues process medical bags through designated gates to minimize screening delays while ensuring thorough safety checks.
Diaper Bags & Infant Care Items
You can use standard diaper bags without converting to clear bags. The policy exists because infants require immediate access to diapers, wipes, formula, and other supplies that genuinely fill more space than the 12″ × 6″ × 12″ limit.
Diaper bag inspection takes extra time because security must check the bag’s contents, but you won’t face rejection. Many stadiums see heavy infant attendance during early-season matches and weekend games, so security staff are accustomed to this process.
You should pack your diaper bag normally and bring it to the medical gate. Expect a thorough inspection of bottles, food containers, and anything that could be prohibited. Once cleared, your bag receives a tag and entry is permitted.
Bag Check & Storage Options
If you arrive with a non-compliant bag or decide you want to bring more than the policy allows, you can use bag check services. Understanding these options prevents the frustration of arriving prepared to enjoy an event only to discover your bag doesn’t meet requirements.
Walker’s Lockers is the primary bag check service at Lumen Field. It’s not a stadium-operated service, but a private partner that operates left-luggage facilities near major venues. You drop your bag off, receive a claim ticket, and pick it up after the event.
Walker’s Lockers Bag Check Service
You pay approximately $8-$12 per bag depending on size and event type. The service operates at designated locations around Lumen Field’s exterior.
You don’t need to reserve lockers in advance. Walk up, pay the fee, drop your bag, and receive a claim ticket. The service is secure with surveillance and attended personnel. You’ll retrieve your bag after the match.
During high-capacity events (concerts, major matches), locker availability sometimes runs out. You should arrive early if you plan to use bag check. Don’t wait until 15 minutes before gates open hoping a locker is available.
Do You Need to Pre-Check Your Bag?
You don’t have to pre-check your bag before stadium entry. You can carry your clear bag through security, then drop your larger bag at Walker’s Lockers if you’re staying for several hours and bought merchandise or picked up items at concessions.
However, if you’re arriving with only a non-compliant bag and no clear bag backup, you must use locker service before security gates. Make this decision before you get in the security line, not during it.
Is the Bag Policy Strictly Enforced?
Yes. Lumen Field enforces the clear bag policy consistently across all attendees. You won’t find flexibility, exceptions for almost-compliant bags, or grace periods for first-time violators. This consistency is actually good news because it means everyone receives equal treatment.
Real attendee experiences from social media and travel forums consistently show that security staff follow the rule exactly as written. You’ll face rejection if your bag is over-sized by half an inch. You’ll face rejection if your bag isn’t fully transparent. Enforcement happens at every entrance and every event type.
What Happens If Your Bag Doesn’t Pass Inspection?
Security will stop you before you enter the security line and explain that your bag doesn’t meet requirements. You have three primary options:
- Return the bag to your vehicle
- Throw it away
- Pay for bag check service if available
Most attendees choose to walk the bag back to their car rather than throw away a personal item or pay storage fees. This means you’ll need to arrive 20-30 minutes earlier than planned to handle non-compliant bags. It’s entirely preventable with proper preparation.
If you drove to the stadium, this inconvenience is manageable. If you took public transportation or rideshare, throwing away your non-compliant bag becomes your only option. This is why you should check bag requirements before event day.
Real Attendee Experiences (Enforcement Stories)
Social media posts from Seattle Sounders matches consistently show that fans with non-compliant bags face rejection without exception.
One Reddit thread from a 2024 match described a woman arriving with a popular fashion brand’s handbag that exceeded the 4.5″ × 6.5″ clutch limit. She got rejected and missed the first 15 minutes of the match walking back to her car.
Another attendee reported arriving with a frosted clear bag they purchased online that was marketed as “clear.” Security rejected it because the frosting created visual obstruction.
The attendee didn’t get angry at the staff. They acknowledged the rule was fair and returned with a fully transparent bag.
These aren’t horror stories meant to scare you. They’re straightforward examples showing that the policy works as intended. The staff isn’t being difficult; they’re following a specific rule consistently.
According to FIFA World Cup 2026 security guidelines, all venues hosting international matches enforce entrance security with the same rigor.

Water Bottles & Other Beverages
You can bring a reusable water bottle into the stadium if it’s empty at entry. Once inside, you’ll find free water stations and fountains available throughout the facility.
You can save money by bringing an empty water bottle. Stadium beverages cost $5-$8, and refilling your bottle from water stations costs nothing.
Many attendees bring lightweight collapsible water bottles specifically because they fit in clear bags and take up minimal space.
Can You Bring a Water Bottle Into Lumen Field?
Yes, but you must have it completely empty when you pass through security. You cannot bring glass bottles. You can bring metal water bottles.
You can bring plastic bottles. You can bring insulated bottles with lids. The only requirement is that the bottle passes through security empty.
You cannot bring bottles with sports drinks, juice, or any pre-filled beverages. You can buy drinks inside the stadium after clearing security, but you cannot bring outside beverages into the venue.
Per U.S. Bank Stadium’s water policy guidelines, most major venues allow empty reusable bottles to encourage sustainability while maintaining security standards.
Hydration Stations & Refill Options
Lumen Field has water fountains and refill stations distributed throughout the stadium. You don’t have to search hard to find one.
Concourse areas near restrooms typically have fountains. Premium club seating has dedicated hydration stations.
Outdoor events in Seattle generally mean mild temperatures, so you won’t need hydration as critically as at indoor events or venues in hot climates.
But you can refill your bottle once or twice during an event to stay comfortable throughout the match without expensive concession purchases.
Preparation Tips for FIFA World Cup 2026
If you’re attending FIFA World Cup 2026 matches at Lumen Field, you’ll face heightened stadium security beyond standard match day protocols. You’ll encounter longer entry lines and stricter enforcement of all policies.
Follow this pre-event checklist to ensure smooth entry:
- Measure your bag width, length, and height against the 12″ × 6″ × 12″ limit
- Choose clear plastic, vinyl, or PVC material for your main bag
- Verify that any backpack has no more than 2 pockets
- Test that your bag is fully transparent with no frosted sections or tints
- Check your small clutch dimensions against the 4.5″ × 6.5″ maximum
- Identify which entrance has the medical/accessibility gate if needed
- Plan your arrival time 30-45 minutes early for heightened security
- Download the Lumen Field app for real-time updates on bag policy changes
The bag policy itself won’t change for the World Cup, but enforcement resources will increase.
This benefits you because it means shorter security lines despite larger crowds. The stricter initial bag check prevents problems deeper in the security process.
