This No. 1 bestselling crossbody bag was my travel VIP for 10 days in Italy, and it's on sale for $22

Spring marks the beginning of a busier travel season, and it's time to stock up on essentials that'll help make every journey as easy as possible. I recently embarked on my own adventure across Italy, and during my travels, I was able to test what shoppers have called "the perfect solution" for on-the-go storage: the Waterfly Crossbody Sling Backpack. And readers, I'm here to say that this bag is indeed ideal for day-tripping through theme parks, tourist hotspots and so much more. Right now, the No. 1 bestselling super sling is down to $22, or nearly 40% off.

The Waterfly has a ton of compartments, including a front zipper pocket, a mesh water bottle holder and a shoulder strap phone pocket.

💰 Why is this a good deal?

Right now, you can score this Amazon bestseller for $22, down from $35. I can assure you that it's more than worth it — and we also haven't seen this crossbody marked down any lower since early January. Now's the time to grab one at a savings if you need to prepare for spring and summer travels.

🤔 Why do I need this?

The Waterfly Crossbody Sling Backpack was the only "purse" I brought on our whirlwind trip through Italy — including Rome, Cinque Terre, Florence and Pompeii — and it held up incredibly through our 10-day adventure. That's no small feat: It was fairly drizzly most of the time we were there, and on certain days, we walked 20,000 steps or more. The bag not only had to stand up to wet conditions, but the rigors of heavy use: me constantly putting it on and taking it off, adjusting the strap and opening it multiple times a day. It also had to carry enough items to get me through up to 12 hours of sightseeing.

And folks: It performed marvelously.

The real value here: The level of organization and storage space afforded by such a deceptively sleek, compact bag. There are a ton of compartments: a larger main zipper compartment, a slide-in pocket that clips shut with the bag, a small zipper compartment on the front, two side mesh water bottle holders, a small zipped pocket on the strap and more. With all of these, I was able to stay prepared for anything. Some days I was able to fit a travel umbrella, reusable water bottle, wallet, passport, guidebook (thanks, Rick Steves), snacks, sunglasses, shawl, Kindle, external battery and extra cords, earbuds, iPhone, toiletries and medications, selfie stick and even more. Phew! That's a wild amount considering the bag isn't exactly massive at 15 by 7 by 3.5 inches.

Oh, yeah: It was comfortable. The shoulder strap is well-padded, but if your shoulder ever gets tired, the bag converts into a fanny pack (it's not necessarily made to do this, but it works perfectly well). It also washes easily — my trusty Sugar-Free Red Bull spilled in one of the pockets, but I simply rinsed out the bag at our hotel and let it air dry, and it was totally fine by the next day.

👍 Pros

"I bought this bag for a trip to Universal Orlando with my son for his 11th birthday. This bag was perfect!" raved one shopper. "It held everything we needed: snacks, ponchos, sunscreen, hand sanitizer, wipes, and even water bottles (I used 9-ounce S'Well bottles, which I highly recommend). I even put a pair of plastic Birkenstocks one day for the water rides. The pouch on the strap fit my iPhone 15 Pro as well as my sunglasses."

One Disneyphile shared: "Based off of multiple positive recommendations from various Disney blogs and discussion boards, I bought this for my trip to Disneyland. It was truly the perfect size, with just enough storage to hold everything I needed it to hold. ... You can easily slip it on and off; with a quick change of the clips, you can switch which shoulder it's on. You can wear it across your front or your back. It's sturdy and keeps the contents inside dry in the rain or on a wet ride at a park. ... I highly recommend this pack, and that is from someone who also owns other day packs from Osprey and Camelback."

"As a frequent traveler, especially now in retirement, finding the perfect bag for my needs has been a priority," wrote another fan. "This backpack is impeccably designed, striking the right balance between size and functionality. ... It's a reliable travel companion, making organization and accessibility a breeze."

👎 Cons

One Disney dad gave the bag a five-star rating, but noted some areas where even this fan favorite could be improved: "One: Add a flap, latch, elastic strap or something similar on those outside mesh pouches so that nothing can fall out. Two: Add a second clip (like the one for keys), buried in the 'roof' of the main pouch or elsewhere so I can clip an Apple AirTag to it."

Snag this bag in 20 different colors, from neutral black to pastel purple to neon yellow.
