Sling Bag vs Crossbody vs Messenger: Which Should You Buy?
25 min reading time
The three names get used for the same bag so often that the labels alone will not help you choose. Shops call a bag a sling in one listing and a crossbody in the next, and a small messenger can look like either.
This guide to sling bag vs crossbody vs messenger sorts them by what matters in use: how the bag sits on your body, how much it holds and what it is awkward at.

What is a sling bag?
A sling bag has one strap and is designed to sit snug against your chest or back. You swing it round to the front to open it without taking it off.
Because it sits high and close, a sling is the most secure of the three in a crowd and the least likely to bounce when you walk fast or cycle.
Choose a sling if you carry only the essentials and want your hands free.
Skip it if you need to carry a tablet, a water bottle and a sweater. It will not fit.
One example is the Men's Brown Leather Sling Bag (SN-18), CA$69.99. It is cowhide, with a main zip compartment, a quick-access front pocket and a back pocket for a phone or passport. The listing notes it can be worn as a chest pack, a back sling or a crossbody. For a black option, see the Men's Black Leather Sling Bag (SN-11), CA$89.99.
What is a crossbody bag?
A crossbody bag hangs at your hip on a long strap that runs from one shoulder across your body. The term describes how the bag is worn more than its shape, so crossbody bags range from small pouches to structured handbags with a long strap.
A crossbody spreads weight better than a shoulder bag and is easy to reach into while you walk.
Choose a crossbody if you want one bag for errands, travel days and evenings out.
Skip it if you carry paperwork or a laptop. Most are too small.
A messenger bag is the largest of the three. It is wider than it is tall, closes with a flap or zips, and is built to carry flat items such as documents and a tablet.
It is also worn across the body, which is why the terms overlap. The difference is purpose. A messenger is a work bag.
Choose a messenger if you carry papers, a tablet, a charger and your daily items together.
Skip it if you carry very little. A half-empty messenger is bulkier than you need.
Add sunglasses, a small umbrella or a book: crossbody bag.
Add a tablet or paperwork: messenger bag.
Add a laptop every day: a messenger or laptop bag that states its laptop size.
If you are between two, choose the smaller one. A bag that is slightly too small makes you carry less. A bag that is too big fills up.
Decide by how you get around
Transit and crowds. A sling worn on the chest keeps zips in view.
Walking long distances. A sling or a light crossbody puts the least strain on one shoulder.
Cycling. A sling stays put. A messenger works if it has a snug strap.
Driving. Any of the three works. A crossbody is the easiest to take on and off.
Winter coats. Thick layers shorten the usable strap. Check that it adjusts long enough to go over a parka.
Leather sling bag for men, crossbody bag for women?
That is how the styles are often marketed, but it is not a rule. Slings and messengers are sold mainly to men and structured crossbody bags mainly to women, yet plenty of bags in each group suit anyone.
Choose by size, strap length and how the bag sits on you. Several bags in our collections are listed for both men and women.
Comfort and care
All three styles load one shoulder. Switch sides from time to time and avoid overfilling.
Leather is not waterproof. After rain or wet snow, wipe the bag with a soft dry cloth and let it dry at room temperature. Our guide on whether leather bags are waterproof has more on care.

Frequently asked questions
What is the difference between a sling bag and a crossbody bag?
A sling bag sits tight against the chest or back on a single strap and is usually small. A crossbody bag hangs lower, at the hip, on a longer strap and comes in more shapes and sizes. Many bags can be worn both ways, so the names overlap.
Is a sling bag or a crossbody better for travel?
A sling worn on the chest is more secure in crowds and stays in place when you move quickly. A crossbody usually holds more and is easier to open while it hangs at your side. For a passport, phone and wallet, a sling is enough.
Can a messenger bag replace a backpack?
For a light load, yes. A messenger carries documents, a tablet and daily items and is quicker to open than a backpack. For heavy loads or long walks, a backpack is more comfortable because it spreads the weight across both shoulders.
