Quick answer

For most convention-goers, a 20–30L backpack with a padded laptop sleeve, lockable main compartment, and water-resistant zippers is the best bag for cons. If you carry a lot of pins or small merch, add a dedicated pin display or organizer. Vendors should size up to 30–40L with reinforced straps and a separate cash pouch. The right gaming convention bag balances capacity, comfort, and security for your specific role.

You have your badge, your schedule, and your comfy shoes. But the wrong bag can turn a great convention into a day of shoulder pain and lost merch. This convention bag guide cuts through the noise with concrete decision rules so you can pick a bag that actually works for how you con.

We will cover capacity, carry comfort, security, and organization—then give you a fit guide for day-trippers, cosplayers, and vendors. Along the way, we will point out a few small merch items that pair well with a con bag, like pins and socks, so you can carry your fandom without overpacking.

Rule 1: Match capacity to your con day

Capacity is the first decision because it dictates everything else. For a single-day attendee, 20–30L is the sweet spot: enough for a water bottle, snacks, a light jacket, a portable charger, and a small merch haul. If you are a vendor or carry camera gear, look at 30–40L with compression straps to keep the load stable.

Do not default to the biggest bag you own. Oversized bags are heavier, harder to maneuver in crowded aisles, and more likely to be flagged at bag check. Measure your typical load: a 15-inch laptop, a switch, a couple of art prints, and a plush. If it fits in 25L, stop there.

  • Day-tripper: 20–25L backpack with a laptop sleeve.
  • Vendor or press: 30–40L with reinforced straps and a separate cash or battery pouch.
  • Cosplayer: 15–20L sling or small backpack for repair kit, makeup, and phone.

Rule 2: Prioritize carry comfort over extra pockets

You will wear this bag for 8–12 hours, often while standing in lines. Padded shoulder straps and a ventilated back panel matter more than a dozen tiny pockets. Look for a sternum strap if you walk a lot; it keeps the load from shifting when you bend down for a dropped pin.

If you are between sizes, choose the bag with the more adjustable harness. A bag that sits too low will pull on your shoulders; one that sits too high can bump your head. Adjust the straps so the bag rests in the middle of your back, and test it with weight before the con.

  • Look for breathable mesh on the back panel—it reduces sweat between panels.
  • A hip belt helps only if the bag is 30L or larger; on small bags it just adds bulk.

Rule 3: Security features are non-negotiable

Con floors are busy, and a bag with easy-access pockets is an open invitation. Choose a bag with lockable zippers on the main compartment, or at least zippers you can clip together with a small carabiner. A hidden back panel pocket for your phone and wallet is worth more than a fancy front organizer.

If you carry collectible pins, keep them in an interior pocket or a pin display that zips shut. Losing a limited pin hurts more than losing a granola bar. For extra peace of mind, use a small lock on the main compartment when you set the bag down at a demo station.

  • Test zipper pulls with gloves—you may be wearing cosplay gloves or it may be cold.
  • Avoid bags with open side pockets for water bottles; choose a zippered or elastic-secured pocket.

Rule 4: Organize for quick access and merch protection

A cluttered bag wastes time and risks damage. Use a simple system: one pocket for essentials (badge, phone, wallet), one for gear (charger, cables, snacks), and one for merch. If you buy art prints, carry a rigid folder or tube to prevent bending. For pins, a small pin bag or a dedicated pin display keeps backs from scratching.

Small items like socks or a pin can be tucked into a side pocket so they do not get crushed. If you plan to buy a plush, leave a little empty space—or bring a compressible tote as a backup.

  • Pack a small pouch for pin backs and tools; loose backs disappear in bag lint.
  • Keep a folded tote in your bag for overflow merch so you do not overstuff your main compartment.

Decision rules for your con bag

  • Capacity first: Choose 20–30L for a standard day, 30–40L for vendor or heavy gear. Do not size up unless you have a specific need. Pack your typical load and measure it before buying.
  • Comfort beats pockets: Prioritize padded straps, a ventilated back panel, and a sternum strap over extra compartments. Wear the bag for 10 minutes with weight before the con.
  • Security is a feature: Look for lockable zippers, a hidden back pocket, and zippered side pockets. Keep pins and small merch in a closed interior pocket. Use a small carabiner to clip zipper pulls together.
  • Organize by role: Essentials up front, gear in the middle, merch in a protected compartment. Add a rigid folder for art prints. Do a dry run packing your bag the night before.

Small merch that works with your con bag

  • Five Nights at Freddy's - Character Pixel Knee Socks: These knee socks feature pixel characters from Five Nights at Freddy's and are made for wearing, not just displaying. They add fandom to your con outfit without taking up bag space, and they are easy to swap if your feet get hot.
  • Shovel Knight - Specter Knight Collector's Pin: This official Shovel Knight pin is a small collectible that can be attached to a bag strap or a pin display. It lets you show off a favorite character while keeping your hands free, and it is light enough to carry all day.
  • Rain World - Survivor Looks to the Moon Foil Art Print: This foil art print measures a standard size and is printed on foil material, so it needs protection from bending. If you buy art prints at a con, carry a rigid folder or tube in your bag to keep them flat and uncreased.

Find your fit

Best for

  • Day-trippers who carry a water bottle, charger, and a small merch haul
  • Cosplayers who need quick access to a repair kit and phone
  • Vendors who need a 30–40L bag with reinforced straps and a cash pouch

Not for

  • Attendees who only carry a phone and wallet—a sling or fanny pack is lighter
  • Collectors who buy large art prints and need a dedicated portfolio case
  • Anyone who prefers a rolling case and does not want to carry weight

Choose your gaming convention bag by capacity, comfort, security, and organization—in that order. A 20–30L backpack with lockable zippers and padded straps will serve most con-goers well, while vendors should size up. Pack it once before the event, and you can focus on the fun instead of your shoulders.
