Best all-around hiking backpack

Product Name

Price: 0.00$

Osprey is renowned for making some of the world’s most ergonomic hiking backpacks. In particular, the Aether 55 Backpack speaks to the brand’s greatest strengths. With a 55L carrying capacity, this pack is equally suited to a year-long tramp around the globe as it is to a weekend glamping trip.

Features unique to Osprey, like their custom Fit-on-the-Fly hip belt and shoulder straps, allow for better weight distribution and more stability. This translates to a substantial increase in comfort. The torso length is also adjustable.

A built-in hydration sleeve makes water easily accessible, while a DWR-treated rainfly is always ready for a downpour. The LightWire frame also means a lower base weight, which even ultralighters can get behind. Overall, the Aether 55 Backpack has something for everyone.

As usual, you can expect the ultimate in backpacking comfort and ventilation thanks to Osprey’s patented AirScape back panel. The zippered sleeping bag compartment makes it easy to store and organize your gear for weekend treks, while the integrated, removable rainfly keeps your stuff dry on wet adventures.

Best backpack for minimalists

The Exos 48L is Osprey’s entry into the minimalist backpacking world. What we have here is as comfortable and functional as any Osprey bag, but with fewer frills and a lighter weight. Though the backpack is unisex, women also have the option of a more ergonomic version, embodied by the Eja 48L.

AirSpeed ventilation and an Exoform harness ensure that the pack is sturdy, comfortable, and well-ventilated. The Exos boasts a weight of just 2.5lbs. If 48L is not quite or more than enough, you can opt for the 38L and 58L versions, respectively. As always with Osprey’s packs, both the Exos and the Eja are backed by their All-Mighty Guarantee.

WHAT TO LOOK FOR WHEN BUYING A HIKING BACKPACK

Here we quickly touch on some of the main criteria when choosing the right backpacking pack for your needs. For more in-depth coverage on the topic, check out our article, How to Choose a Hiking Backpack.

Volume Options

Choosing the right pack volume has to do with the remoteness, local climate, carry preferences, and duration of your trip. Nevertheless, here is a hard-and-fast rule to make this choice simpler.

  • 1-3 Nights: 30 – 50 Litres 
  • 3-5 Nights: 50 – 80 Litres
  • 5+ Nights: 70+ Litres

Compartments

Knowing where everything is in your pack and being able to have quick access is a must. Having a well-organized, functional pack comes down to the number and layout of the compartments. Below are some compartment types to look for. 

Pockets

Your hiking backpack itself is like a giant pocket, fit for carrying your gear, food, and anything else that needs to stay dry. A top-lid “brain” pocket is a great place to stash items you frequently use (GPS, map, compass, etc.), while outside pockets are designed to keep your water bottles handy (assuming you don’t have a hydration pocket—see below). Finally, hip belt pockets can be used to conveniently store little items (like a Clif Bar and your phone) on your waist. 

Hydration

Similar to laptop sleeves, hydration sleeves are sewn into the inside back panel of the bag. It’s a long, narrow compartment designed to hold something called a “bladder”. The volume of water a bladder can hold depends on the size of the particular sleeve. A hose connected to the bladder passes through a small opening so you can access it directly. This means you don’t have to stop everytime you want to hydrate.

Detachable Daypack

Detachable daypacks are featured on many larger or long-distance hiking packs. They are part of the main body which, when removed, allows you to ditch your hulking load for a smaller pack. This is useful when you’ve set up a home base and are just heading out for the day, or if you’re summiting a precipitous peak and want to stay light.

Comfort & Support

It’s always best to try out a backpacking pack before buying it. Comfort means you can spend more time enjoying your adventure and less time focusing on that weird new kink in your back. A backpack’s support system translates directly to comfort.

Shoulder Straps

Having a well-padded shoulder strap is important, especially for larger packs and heavier loads. Make sure the straps are comfortably padded and wide enough apart relative to your shoulder width. Otherwise, you might find them chafing your neck and shoulders.

Waist Belt

Waist- or hip-belts are essential to proper weight distribution. A hip-belt should offer good support and padding, so as not to cause excessive chafing and pain. Make sure you can tighten the waist straps adequately. If the hip-belt feels loose at its maximum squeeze, consider sizing down.

Ventilation 

Osprey has led the revolution in backpack ventilation. Their patented AirScape technology incorporates mesh-covered 3D foam-back panels, which allow air to travel between your back and your backpack, helping you stay cool and dry. 

Many other companies have begun to incorporate similar technology into their packs. Just be sure to try the pack on (with a full load) to verify whether the weight distribution is affected by the ventilation gap.

FAQs for hiking backpacks

Q: How heavy should a backpacking pack be?

A: This depends on factors like the fabrics used in its construction, the amount of hardware and features, and the size of the pack: the more frills, the greater the weight. To keep the pack’s initial weight as low as possible, take some time to consider exactly which features you need and which you can do without. If you really want to go ultralight, remember that ultralight backpacks have a lower carrying capacity than their heavier counterparts of the same volume.

Q: What is considered a lightweight backpack?

A: There is no precise answer to this, but when looking for the lightest pack on the market, make sure to only compare packs of the same volume (40L to 40L, 65L to 65L, etc.). As a rule of thumb, ultralight packs tend to have fewer features, less hardware, and a lower carrying capacity.

Q: Can backpacking packs be carry-ons?

A: In general, yes. But it’s always wise to check the weight and size restrictions for carry-ons with the airline before you fly. Also, things like hiking poles and gas canisters won’t be permitted on your flight, so ensure that your bag is free of any prohibited items—otherwise, you’ll have to check it.
