Nats Park Bag Policy Guide
Heading to a Washington Nationals game? The Nats Park bag policy is known as one of the strictest in Major League Baseball, and knowing the exact rules is the difference between walking straight to your seat and being sent back to your car. Because stadium entry rules vary by event, gate, and security team, this guide breaks down exactly what you can and cannot bring into the ballpark.
Direct Answer: Nationals Park enforces a strict clear bag policy with an absolute ban on backpacks. The safest choice for entry is a 12" x 12" x 6" clear tote bag. You may also bring a small non-clear clutch no larger than 5" x 7" x ¾". If your bag does not meet these rules or has backpack-style straps, it will be rejected. If this happens, you can rent a Binbox storage locker located just outside the stadium gates.

How We Check This Policy
At BagPolicyGuide.com, we prioritize official league and venue documentation to provide the most accurate entry requirements. We separate confirmed official rules from general stadium practices. Because security procedures can change based on the event or the specific guard at your gate, we recommend using our safest practical recommendation to avoid delays or locker fees.
Official Bag Policy Overview
Nationals Park officially operates under a "No Bag" policy, meaning they strongly prefer fans to enter without any bags at all to speed up screening. However, they do allow standard clear bag rules to accommodate essentials.
You may bring a clear bag up to 12" x 12" x 6", a one-gallon clear freezer bag, or a small clutch. Any bag that does not fit into these strict categories will be turned away at the gate.
What Makes This Bag Policy Different
The single biggest issue fans face at Nationals Park is the absolute ban on backpacks. While other venues like Yankee Stadium or Wrigley Field have their own unique restrictions, Nats Park is incredibly strict about bag styles with two shoulder straps.
Security guards frequently reject bags with a backpack-style design, even if the bag is fully clear and perfectly matches the 12" x 12" x 6" size limit. If you are coming straight from work or school with a laptop bag or backpack, you will almost certainly be forced to rent a locker.
Allowed Bags and Size Limits
Clear bags
Clear totes, plastic one-gallon freezer bags, and clear cinch bags are permitted as long as they do not exceed 12" x 12" x 6". The bag must be transparent on all sides, without large logos or opaque panels that block the view inside.
Small clutches and wallets
You do not need a clear bag if you only carry a tiny purse, wristlet, or clutch. These non-clear bags must be no larger than 5” x 7” x ¾” (roughly the size of an adult hand or a large smartphone).
Backpacks, purses, and crossbody bags
Standard purses and crossbody bags are only allowed if they are clear and within the 12" x 12" x 6" limit. Non-clear purses larger than a 5" x 7" clutch are strictly prohibited. As stated, all backpacks-regardless of material or transparency-are banned.
Diaper bags, medical bags, and ADA exceptions
Nationals Park accommodates families and individuals with medical needs. Bags required for medical necessity (including breast pumps) or manufactured diaper bags (when accompanied by an infant or toddler) are permitted. These exceptions do not have to be clear, but they must fit within a 16" x 16" x 8" footprint. Be prepared for a manual visual inspection at the designated medical/family lanes.
Prohibited Bags and Items
To avoid being turned away, never pack these commonly prohibited items:
- Backpacks of any kind (clear, opaque, leather, nylon, cinch, or drawstring).
- Oversized non-clear bags (purses, totes, or fanny packs larger than 5" x 7" x ¾").
- Coolers (both hard-sided and soft-sided are banned).
- Luggage and large camera bags (suitcases, duffels, and professional camera gear with lenses over 8").
- Umbrellas with metal tips (small, collapsible umbrellas are allowed but must be stored under your seat).
- Glass bottles and metal cans (empty reusable plastic or metal water bottles are allowed).
How Security Screening Works
Nats Park utilizes advanced security screening technology, often walk-through systems like CEIA OpenGate. This allows you to walk through the detectors without removing your phone, keys, or wallet from your pockets.
If you bring a bag, you will be directed to a bag-check lane where staff will visually inspect its contents. If security decides your bag is too large, too opaque, or has backpack straps, you will be directed away from the gate. You can then download the Binbox app, pay a rental fee, and secure your prohibited bag in a locker located outside the Right Field Gate or Left Field/Home Plate Gate.
Packing Strategy for Faster Entry
- Choose the safest bag: A standard 12" x 12" x 6" clear tote bag with shoulder straps is the best way to avoid the backpack debate completely.
- Use small pouches carefully: You can place your 5" x 7" non-clear clutch inside your clear tote for privacy. Do not use multiple oversized opaque pouches, or security will ask you to empty the bag.
- Keep essentials visible: Pack your sealed water bottle and snacks at the bottom, and place your phone and keys near the top for an instant visual check.
- Make a backup plan: If you are traveling via the Metro and bringing a questionable bag, download the Binbox app at home so you don't waste data or time at the gate.
Security Check Anxiety Tips
If you are worried about the strict rules holding you up, preparation is your best defense. Double-check your bag size with a tape measure before you leave the house. Have your mobile tickets open on your phone screen before you reach the front of the line.
If you are carrying a medical bag or a diaper bag and a security guard questions it, stay calm. Politely explain that it is a medical or infant necessity. If the guard still refuses entry, respectfully ask to speak with a guest services supervisor who is trained in ADA and stadium exceptions.
Day-of Entry Tips From BagPolicyGuide
These practical tips help you avoid gate denial and reduce security check anxiety on game day.
- Arrive 45 to 60 minutes early. Security lines peak about 30 minutes before the first pitch. Arriving early keeps you out of the longest, most stressful crowds.
- Avoid the Center Field Gate if crowded. The gate near the Navy Yard Metro gets overwhelmed fast. Walking to the Left Field or Right Field gates often results in much faster entry.
- Screenshot the official policy page. Cell service can drop in large crowds. Having an offline image of the medical/diaper bag rules helps clear up confusion with security.
- Leave the laptop at home. Laptop bags and backpacks are the most frequently rejected items, forcing you into paid locker lines.
- Keep your umbrella small. If rain is in the forecast, pack a disposable poncho or a tiny, collapsible umbrella. Large umbrellas with metal tips will be confiscated.
- Pack one water bottle. You are allowed one factory-sealed, clear plastic water bottle (1 liter or less) to stay hydrated in the summer heat.
Category-Specific Packing Tips: MLB Stadiums
- Sun Protection: Nationals Park can be incredibly hot during afternoon games, and shade is limited in many sections. Pack sunscreen (lotion, not aerosol) and a hat inside your clear bag.
- Save Money on Food: Nats Park allows you to bring outside food as long as it is stored in a clear plastic bag or your 12" x 12" x 6" clear tote. This is a great way for families to save money on stadium snacks.
- Empty Bottles: If you don't want to buy water, bring an empty reusable bottle. You can fill it at water fountains inside the concourse once you pass security.
