Sloan Park Bag Policy 2026: Size Limits, Prohibited Bags & Entry Guide
If you are heading to Sloan Park for Chicago Cubs spring training in Mesa, Arizona, the sloan park bag policy is stricter than many fans expect. Bags smaller than 16″ x 16″ x 8″ are permitted, but backpacks of any kind — including clear backpacks — are not allowed inside the ballpark.
This guide breaks down the official size limits, which bags get waved through fastest, what security screening looks like at the gates, and what to do if your bag is too big. Everything below reflects the Cubs’ published ballpark terms for Sloan Park, checked in November 2026.

Official Policy Verification & Source Check
- Official source: Chicago Cubs ballpark terms for Sloan Park, published through the Cubs’ official game-day information (cubs.com / MLB).
- Source type: Team-published ballpark policy for spring training games.
- Last checked: November 2026.
- Confidence level: High. The size limits below appear consistently across multiple third-party reports quoting the Cubs’ ballpark terms, and they match the Cubs’ Wrigley Field policy wording. Note: the MLB.com Sloan Park pages could not be fetched directly during research, so the figures below reflect the Cubs’ published terms as quoted in third-party coverage — cross-check the ballpark’s A-Z guide before Opening Day.
- Notes on conflicting figures: Some third-party venue pages phrase the limit as a hard “max 16″ x 16″ x 8″” while the Cubs’ terms say bags smaller than 16″ x 16″ x 8″ are permitted — in practice the same rule, and the safest read is to stay under the stated dimensions. Do not confuse this with the Breakaway music festival held at the Sloan Park Festival Grounds, which used a stricter 12″ x 12″ x 6″ clear-bag-only rule (reported by azcentral, April 2026) — that was an event-specific policy, not the Cubs spring-training rule. A 2021 report citing “small bags 9×5 inches or smaller” reflected COVID-era restrictions and no longer applies.
How We Check This Policy: We compare the venue’s or team’s own published terms against secondary reporting and fan-facing venue guides, then flag every mismatch we find. When the official page itself is unreachable, as happened here with the MLB.com Sloan Park pages, we say so plainly and rely on the most consistent quoted figures — in this case the Cubs’ “smaller than 16 x 16 x 8” rule, which is corroborated by the identical wording in the Cubs’ Wrigley Field policy.
What Makes Sloan Park’s Bag Policy Different
Sloan Park follows the Chicago Cubs’ standard ballpark template — the same “smaller than 16 x 16 x 8” limit and the same backpack ban you will find at Wrigley Field. What makes the spring-training experience different is the setting, not the rulebook.
The ballpark leans heavily on its grass berm and open concourse, and gates open a full 90 minutes before first pitch, which spreads the entry crowd out. That generous window means bag checks rarely create the long lines you might expect at a regular-season MLB game.
The bigger practical difference is event variety. Sloan Park doubles as a concert and festival venue, and those events can carry much stricter clear-bag-only rules than Cubs baseball games do. Always check the policy for your specific event — the spring-training bag rules below apply to Cubs games, not to festivals on the Sloan Park Festival Grounds.
Allowed Bags and Size Limits
| Bag Type | Entry Status | Max Dimensions | Conditions |
|---|---|---|---|
| Small purses and crossbody bags | Allowed | Smaller than 16″ x 16″ x 8″ | Subject to inspection at the gate |
| Wallets and wristlets | Allowed | No stated limit | Fastest entry — rarely inspected in depth |
| Drawstring bags | Allowed | Smaller than 16″ x 16″ x 8″ | Subject to inspection |
| Fanny packs and waist packs | Allowed | Smaller than 16″ x 16″ x 8″ | Subject to inspection |
| Lunch bags and soft-sided coolers | Allowed | Smaller than 16″ x 16″ x 8″ | Sealed water bottles and personal food are permitted inside |
| Clear totes | Allowed | Smaller than 16″ x 16″ x 8″ | Not required, but speed up inspection |
| Diaper bags | Allowed with exception | Reasonable size | Child must be present; inspected at the gate |
| Medical bags | Allowed with exception | Reasonable size | Inspected at the gate |
| Backpacks (any kind) | Prohibited | — | Includes clear backpacks |
| Hard-sided coolers | Prohibited | Any size | No exceptions by size |
| Luggage and oversized bags | Prohibited | 16″ x 16″ x 8″ or larger | Must be returned to your vehicle |
Purses, Totes and Everyday Bags
Most everyday purses, crossbody bags, and small totes fall comfortably under the 16″ x 16″ x 8″ ceiling. The rule targets oversized tote bags and full-size backpacks, not normal game-day purses.
A clear tote is the single best choice if you carry a lot. It is not required by the Cubs, but security staff can see inside instantly, which moves you through inspection noticeably faster on busy weekend games.
Diaper and Medical Bags
Diaper bags are permitted when you are accompanied by a small child, and medical bags are permitted for guests with medical needs. Both are inspected at the gate, so build in a few extra minutes if you are entering with either one.
Keep diapers, bottles, and medical supplies in one easy-to-open bag. The quicker staff can see the contents, the quicker you are through — and the Cubs specifically direct these exceptions through standard gate inspection rather than a separate lane.
Security Screening: How Entry Actually Works
Gates at Sloan Park open 90 minutes before the scheduled first pitch of spring training games. Arriving early is the easiest way to skip the pre-game rush, especially for weekend matchups and split-squad days.
Every bag is subject to inspection by ballpark staff or security at the gates. Expect a visual check of the interior and possibly a handheld wand or pat-down in line with standard MLB spring-training screening.
Tickets are mobile-only through the MLB Ballpark app, so have your phone charged and your tickets loaded before you reach the gate. You do not need to empty your pockets of phones or keys during screening.
On-Site Bag Storage
The Cubs do not offer large bag or luggage storage at Sloan Park. If your bag fails the size check at the gate, your only option is to take it back to your vehicle.
Parking lots surround the ballpark, but the walk can be long on a hot Mesa afternoon — one spring-training guide warns that fans have been sent on a lengthy trek back to their cars over a purse that was two inches too big. Measure your bag before you leave the hotel, not at the gate.
Food, Beverage and Other Prohibited Items
Sloan Park is friendlier than most ballparks on outside food and drink. Factory-sealed water bottles and outside non-alcoholic beverages are permitted, and outside food is allowed when carried in a clear bag.
That said, the food rules can shift by season, so treat sealed water as the safe bet and check the current ballpark guide before packing a full picnic. Outside alcohol is never permitted.
Prohibited Items
- Backpacks of any kind, including clear backpacks
- Hard-sided coolers, regardless of size
- Any bag measuring 16″ x 16″ x 8″ or larger
- Weapons and fireworks of any kind
- Outside alcoholic beverages
- Glass containers
- Laser pointers and noisemakers
- Drones
- Professional camera equipment used for commercial purposes
- Smoking outside designated areas
Packing Strategy for Faster Entry
- Measure before you go: Lay your bag next to a tape measure at home. Anything at or above 16″ x 16″ x 8″ stays in the car.
- Go clear if you can: A clear tote under the size limit is the fastest bag through the inspection line.
- Skip the backpack entirely: Even a small or clear backpack is turned away — redistribute into a tote or fanny pack instead.
- Consolidate into one bag: Fewer bags mean fewer inspections. One compliant tote beats a purse plus a lunch bag.
- Keep tickets ready: Load your mobile tickets in the Ballpark app before you reach the gate to avoid holding up the line.
Category-Specific Packing Tips
Families with kids: Bring one diaper bag per child and keep it packed light for inspection. Strollers are permitted, and the berm gives kids room to spread out — pack sunscreen and sealed water.
Berm and lawn sitters: You will be sitting on grass in direct Arizona sun. A small soft-sided cooler (under the size limit) with sealed water bottles plus a blanket covers most of your needs.
Autograph seekers: Practices on the back fields start around 9 AM on most days. Travel light with just a fanny pack — you will move between fields and the ballpark, and a small bag keeps you mobile.
Photographers: Non-professional cameras for personal use are fine, but camera bags and bulky equipment cases count against the size limit. Bring the camera on a strap rather than in a dedicated bag.
