This crossbody is pretty much the perfect size you need for your theme park adventures — and it’s definitely the first thing you need. So one big mistake I see people make at the park is one of two things: either bringing an oversized backpack packed to the brim with things, or not bringing any bag at all. Now, I know most people’s first instinct is to bring the largest backpack they own, but frankly, those people quickly realize how big of a mistake it is after their first day of walking all day long in the Florida heat carrying wayyyy too many pounds on their shoulders. Plus, huge backpacks are super annoying to bring onto rides, since at Disney you need to place the bag at your feet (large items will not fit comfortably), and at Universal you need to place any bag into a locker (which are pretty small and only fit small bags, like this one). 

This bag is pretty much the perfect size because it can comfortably slip into a Universal locker, and it’s a good size to place at your feet on a Disney ride without getting super annoyed midway through the coaster. It’s large enough to hold all your essentials — and has a space for your bottle and umbrella (both are must-haves in Florida). 

Promising review: “This bag was helpful during our trip to Disneyland. We put our super important things, like phones, wallets, keys, etc., in the bag and left our diaper bag with our stroller while we went on rides. It gave us peace of mind knowing we had our important items with us and that they were secured on me. The bag was super comfortable to wear and easy to take on and off. And knowing I can use this bag again for similar situations makes me even happier I bought it. If you’re on the fence, buy this bag! You won’t regret it!” —HalesComet

Promising review: “Bought this before going to Universal Studios Orlando and the Theme Parks with the purpose of utilizing this to hold extra power banks, water, and other small items such as a poncho, beanie, and snacks. Let me tell you – it is definitely a must-have. Got to wear it on most rides, instead of placing it in the lockers, saving valuable time.” —Abbas Qureshi
