The best way to ensure your gear does not get damaged in transit or in storage is by having a dedicated paintball gearbag, these are typically large roller gear bags that are specifically designed to be large enough to hold all of your gear including multiples of certain items. Some bags will feature an expansion flap that lets them expand to a larger size if needed, others may have a variety of compartments to help you stay organized, others may be completely open inside, allowing you to stack all your gear however it may fit, maximizing how much can go in it.
Gear bags for paintball can be mostly divided into 3 main categories, Backpacks, Duffel bags, and Roller Gear bags. The backpack style is great for anyone who has one full setup and gear that they are taking to the field, these bags are easy to store, transport, and can typically be used as a great carry-on bag while traveling. The Duffel style bags are exactly as the name sounds, a lightweight duffel bag that usually is going to have one large open compartment, and sometimes a side pocket or two, these are usually best used in addition to another bag, as the shape of them limits how much storage they have. If you are using a duffel bag, it is recommended to have additional cases to protect your gear inside as this offers little protection against things banging into the bag or even items in the bag shuffling around. Last but certainly not least, the Roller gear bags are a large specialty bag designed just for paintball. Depending on the style, these feature wheels suitable for dirt, gravel, turf, grass, mud, or whatever terrain you may encounter at the field, a collapsible pull handle, and they may include a lot of compartments meant for different types of gear such as goggles, tanks, hoppers, swabs, ect. Others may have one large open compartment but may feature additional compartments on the sides. All roller gear bags are designed to protect your gear in transit and storage, so these will typically have more overall protection than other bags.
