When you’re searching for the perfect travel sling backpack, you’re likely on the hunt for something that checks all the boxes: versatile, stylish, durable, practical, lightweight, and comfortable. It should keep up with you on every adventure, whether you’re strolling through bustling city streets or exploring nature trails. And, of course, it needs to be secure and weatherproof, because the last thing you want is to get caught in a downpour without proper protection for your essentials.
This bag has to do it all because, without these features, your journey could turn from smooth sailing to a logistical nightmare. That’s why I decided to invest in one of Amazon’s best-selling travel/day bags, the Mosiso Sling Backpack. It’s a multi-functional sling bag that can also be used as a backpack, described as a messenger bag, crossbody bag, daypack, and shoulder bag all in one. With so much versatility packed into one bag, I was eager to see if it lived up to the hype.
Why I bought the Mosiso sling backpack
I’ll be honest—when it came time to replace my trusty old backpack, I was at a bit of a loss. My previous bag was my go-to for both travel and everyday use, offering just enough room for my essentials, including toiletries, a change of clothes, and my laptop. But with my new carry-on bag taking care of the bigger items, I needed something smaller, more versatile, that could serve as both a purse and a day bag.
I was on the lookout for a bag that could carry the necessities—things like a water bottle, umbrella, and a few other items—while still being comfortable enough to wear all day. The ability to switch between shoulders was a must, too, as I didn’t want to be restricted to carrying it on one side.
Ultimately, I wanted something that was compact but could still hold everything I needed without looking oversized or bulky. And, of course, it had to be stylish.
Several of my fellow travelers recommended the Mosiso Sling Backpack from Amazon. They raved about how practical it was, and after reading through the reviews, I decided to give it a shot.
First Impressions: Material and Aesthetics
At first glance, the Mosiso Sling Backpack seemed almost too simple. I wondered if it would really be able to hold everything I needed. But I quickly realized that its minimalist design is actually one of its best features. The sleek, triangular shape is perfect for travel, and despite its compact size, the tailored fit and multiple storage compartments make it incredibly functional.
The Mosiso Sling Backpack measures approximately 12.44 x 10.35 x 3.43 inches and weighs just under one pound, making it easy to carry around all day. While it’s not meant to replace a full-sized backpack, it’s roomy enough for your daily essentials. You can fit your wallet, keys, documents, phone, and even an 8-ounce water bottle in the side pocket. Just don’t expect it to carry much more than the basics—it’s designed to be a lightweight, everyday bag rather than a full-on travel pack.
The exterior is made of durable polyester, which offers protection against the elements and makes it easy to wipe clean. When it came to choosing a color, I initially wanted something vibrant, like red, orange, or yellow. However, I also wanted to blend in while traveling, so I opted for the classic black. It’s versatile, doesn’t draw too much attention, and goes with everything. If I end up loving the bag as much as I think I will, I can always go back and get one in a brighter color.
Smart Storage: The Compartments
One of the most important features of any bag is how easy it is to find what you need quickly. A well-organized bag can make all the difference, and the Mosiso Sling Backpack strikes a great balance with its compartments.
The bag has four main compartments, starting with a flat pouch on the front that’s secured with a silver zipper. This is where I keep my phone and money—items I need quick access to. The pouch also features a cable access hole, which is perfect for those who still use wired headphones.
Behind the pouch is an open area where I stash my cosmetic bag, hand sanitizer, and other small items. This section doesn’t have a closure, so it’s ideal for things you might need to grab in a hurry.
The main pocket is protected by a zipper and includes an inner pocket that perfectly fits my mini iPad. I can also fit my fold-up jacket, tech accessories, and a few other essentials in this space. My 10-inch Samsung tablet also fits snugly, which was a pleasant surprise.
On the sides, you’ll find mesh pockets that are great for holding a water bottle and umbrella. These pockets are sturdy and keep everything in place, which is a big plus when you’re on the move.
Versatility and Comfort
One of my favorite things about the Mosiso Sling Backpack is its versatility. The adjustable shoulder strap is well-padded and about three inches wide, providing comfort even when the bag is fully loaded. You can easily adjust the strap by pulling the string at the buckle’s end, although I do wish the tail end of the strap didn’t dangle after adjustment—it’s a minor flaw, but it’s something that could be improved.
While this bag is designed to hold a decent amount, it can get heavy if you overpack it. Thankfully, the back of the sling and the shoulder strap are both well-padded to help distribute the weight and prevent back strain. Additionally, the bag has two D-rings on each end, allowing you to switch between carrying it on your right or left shoulder.
