It’s made to be worn on your right shoulder, so bear this in mind if you prefer to wear bags on your left. But aside from that, this is a versatile bag.

Review: This Pacsafe sling is a great option for the security conscious. Aside from being a comfortable and good quality bag, it also comes with multiple anti-theft features including lockable zippers, cut-proof fabric and an RFID safe pocket.

The only downside to the security-focused design is the lack of exterior pockets (just one), so it may not always be the most convenient bag. But, at least you know your things are safe!

Victorinox Altmont Sling Bag

Review: For another top-rated and high-quality option, the Victorinox Altmont is a deceptively spacious bag.

Its sleek, close-fitting design has you fooled into thinking that it won’t hold much, but for most people, it’s more than adequate.

Under Armour Compel Sling 2.0 Backpack

Review: This Under Armour sling offers more of a backpack shape than most slings which is great if you’re looking for something laptop compatible.

The 16.4L capacity is massive compared to most slings which are about half that, so there’s plenty of space for a 15” laptop in the dedicated laptop sleeve.

OutdoorMaster Sling Bag

Review: This bag from OutdoorMaster has loads of great features all available in a high-quality package at a really affordable price.

The highlights include being able to carry a 12” laptop, the ability to switch over the shoulder strap for carrying the bag on either the left or right shoulder, an anti-theft pocket, and a good sized external water bottle pocket on the side.

  • Several compartments.
  • Anti-theft pocket.
  • Water bottle holder.

Maxpedition Sitka Gearslinger

The bag features a main compartment which carries large items like laptops (up to 14.1”) and Ipads.

What is a Sling Bag?

This is a good place to start, because there are actually a lot of different definitions.

For the sake of what is most practical for travel and the purpose of this article, sling bags are considered to be small, narrow backpacks that have just one shoulder strap instead of two.

The strap can be worn over one shoulder or for a more secure and comfortable option, across the body similar to a messenger bag.

But, instead of sitting next to your hip, bouncing while you walk and messing with your posture like a messenger bag, sling backpacks ride in the middle of your back and are comfortable to walk with for longer amounts of time.

But you like messenger bags, I hear you say? Fair enough. There is no one-style-fits-all option when it comes to day bags for traveling.

We have an article dedicated to the best messenger bags for women so head on over there if you think that might be more your cup of tea.

Why the Sling Backpack?

Aside from how hipster they are, sling backpacks have some practical benefits too.

For the lightweight traveler, having a small, comfortable and practical bag for day to day use is pretty important.

Sling backpacks:

  • Make it easy to access their contents without taking the bag off which is a bonus from both a security and convenience perspective.
  • Are cooler to wear in hot weather.
  • Are compact, lightweight and comfortable.
  • Provide just enough room for the essentials without weighing you down.
  • Are the ideal bag to be considered your personal item when flying.

How to Choose the Best Sling Backpack for Travel

But despite their awesomeness, not all sling bags are built equal!

There’s actually a huge variation in design and even definition of what a sling bag is.

So, there are a few things to consider when looking for the best sling backpack for travel.

Which Shoulder?

Most sling backpacks are designed for one shoulder or the other.

Sling backpacks worn over the right shoulder will typically slide around so that the bag can be accessed from under your left arm without having to take it off. Left shoulder sling bags will slide around for access under your right arm.

Which side you prefer will come down to personal preference. But best case scenario, the bag can be worn on either arm.

This means that if you’re carrying more weight and one shoulder starts to get tired, you can switch over.

Pockets and Compartments

Pockets and compartments may sound like an unimportant feature, but the location and number of pockets can actually make or break a bag.

Look for at least one smaller pocket or sleeve for placing small items or valuables so that they are easy to find and keep safe.

Drink bottle sleeves can be useful but are less suited to sling backpacks because the bag will usually be sitting at a diagonal angle across your back. It would have to be a pretty snug fit for your bottle to not be at risk of falling out.

Think about whether you want a separate laptop sleeve, whether you appreciate external pockets or prefer to keep everything safely contained inside the main compartment, and whether a pocket on the shoulder strap (usually for a phone) would be useful to you.

Size and Weight

Sling bags are, by design, usually small and compact. They’re designed to fall somewhere between a small purse and a regular backpack, being just big enough for the essentials.

Think about what the essentials will be for you. If you’re going to want to be able to fit a laptop, this will limit your options as most sling backpacks aren’t big enough.

Bear in mind that since all of the weight is going to be on one shoulder, you don’t want to be carrying too much! And, if you want to use it as your personal item when flying, smaller is definitely better so it doesn’t start to be considered a carry-on bag in its own right.

Teaming up a sling backpack with a wheeled backpack could just be the perfect carry-on combo.

You can wheel your backpack behind you while you wear your sling bag in the airport, and then when you arrive at your destination, you can wear the backpack on your back and the sling on your front!

Alternatively, if you’re looking for one bag to use for carry-on, have a look at our guide to the best carry-on backpacks. The right bag will make a big difference to your flying experience.

Strap Design

Since all of the weight is on one shoulder, you want that shoulder strap to be nicely padded, thick and well-shaped.

Ideally, you want the material to be breathable and soft enough that it won’t irritate your skin if you’re wearing a sleeveless shirt.

Outer Material

Depending on where and when you’re traveling, some water resistance could be useful and give you one less thing to think about if you get caught in the rain.

Also, look for how easy the material is to wash and how durable it is. Machine washable is a huge plus!

Other Options

Despite a good sling bag ticking loads of boxes when it comes to convenience and comfort on the road, I get that they’re not going to be everyone’s bag of choice.

If you know you’re just going to be traveling in urban areas and won’t require all of the practicality of a sling bag, you might consider a travel purse instead.

You’ll blend in with the locals while making the most of some great anti-theft features.

If you know you’re going to be doing a lot of hiking and photography is your jam, I’ll admit, a sling backpack won’t cut it. Check out our guide to the best camera bags for hiking instead.

Why are sling bags popular?

Sling bags have become popular for a number of reasons. Hipsters have a habit of bringing back trends from the 90s, so there’s that.

Are sling backpacks bad or good for your back?

If they’re not too heavy, sling bags are perfectly fine for your back (note: no bag is good for your back exactly).

But overloading your sling bag may affect your posture as all the weight is on one shoulder. So, watch that you keep it to just the essentials.

In saying that, if you already experience back or shoulder pain, you’re probably better off going with something that will keep you more centered right from the start.

We have a list of the best backpacks for problem backs which will help you choose a bag that won’t contribute to your pain.

Are sling backpacks good for hiking?

Sling backpacks are a great choice for summer day hikes when all you need to carry are your phone, wallet, some snacks, water, a warm layer and sunscreen.
