• During a recent trip to Disney, I finally tried using a Loungefly mini backpack as my park bag. 
• I wasn't sure how I'd fit everything I needed in this small bag, but I used it for 10 days straight.
• You can get Loungefly bags directly from Loungefly, in addition to shops like BoxLunch and Disney.

I don't hide the fact that I'm kind of a Disney adult. I follow park blogs, help friends plan trips, and been to the parks a few times. 

If you spend a day in a Disney park, you're likely to see people all over with a huge variety of Loungefly bags, plus more on sale in all the shops. I never fully understood the hype, though — until now.

Aesthetically, the backpacks are all super cute. The brand works with licenses for other major brands like Disney, Marvel, "Star Wars," and "Harry Potter" to create colorful, fandom-inspired mini backpacks, wallets, and crossbody bags.

All of the bags have limited runs, so once they're gone, they're gone, and they typically cost around $75. The backpacks are sold in Disney parks and a variety of online retailers like BoxLunch and 707 Street; in addition to Loungefly's current lineup of products, the brand also works with retailers to release store exclusives. 

Because of its size  — the standard Loungefly backpack is only 10.5 x 9 x 4 inches — I was deterred from the product for a long time. I thought that no matter how pretty some of the designs were, there was no way a bag that small would fit everything I needed. After some convincing by my friends who love theirs, I decided to order my first Loungefly bag: this Marvel Winter Soldier-inspired backpack ($90). 

Everything the Loungefly mini backpack can hold:

I first used my Loungefly bag on a 10-day trip to Walt Disney World. I brought a regular-sized backpack with me as well, because I still wasn't convinced that I'd actually make it through one day with the mini backpack, much less all 10 days of the trip. 

The backpack has a small inside pocket, plus a larger pocket on the outside of the bag. It's made of faux leather that's stiff enough to keep the backpack shape even when nothing is inside of it, but flexible enough to make rummaging around inside easy. One of my favorite aesthetic features is the lining, which is themed specifically to the bag and different with every design. 

I put together all of the things I'd typically put in my backpack for a day in a Disney park: phone chargers, bandaids, a pill case, sunglasses, and a pouch with my cards, medicine, chapstick, and a few other small things. 

After everything was in the bag, I still had some room, so I added a pair of bike shorts and a paperback "Bridgerton" book. 

I was surprised when everything fit, with still some extra space for small souvenirs I bought throughout the day. I ended up using the Loungefly every day of the trip, and it didn't kill my back the way a larger backpack would – there was just enough in it that it didn't feel heavy, but with the extra space in something bigger, I likely would have carried more unnecessary stuff around. 

Cons to consider:

If you're carrying things for more than one person, the Loungefly backpack may be too small to comfortably fit all of the things you need. In my experience, it's also not big enough to use as a carry-on on travel days. 

The bottom line

My recent trip made a Loungefly convert of me. For people like me, who love subtle or not-so-subtle fandom references, Loungefly backpacks are a perfect combination of style and function.
