Main Differences Between the Osprey Aura and Ariel

Even though both Ariel and Aura came from the same company, they differ in certain aspects in order to fit the different needs of various consumers. Here are some of the main differences between Ariel and Aura.


The suspensions of Ariel and Aura are actually very similar to each other. Both of them are incorporated with Osprey’s anti-gravity technology. It comes with a mesh panel and wireframe that effectively hugs your back from top to bottom. Their main difference when it comes to suspension is their hip belts. Ariel comes with an IsoForm 5 CM hip belt, while Aura has a fit on the fit-on-the-fly hip belt, which we will discuss later.


Two very convenient things about the Osprey Ariel pack is its access zipper on the front and its removable daypack that attaches to the top lid of the pack. Meanwhile, Osprey Aura comes with an additional pocket. However, in terms of easier access, Ariel beats Aura regardless of the latter’s extra pocket.


The Osprey Aura is applicable for a wide range of outdoor trips. This makes Aura more versatile, especially since it can carry both light and heavy loads comfortably. On the other hand, Ariel is more suitable for long and heavy load trips, which include trips with children, alpine expeditions, and thru-hikes.

When it comes to the comfort factor, Osprey Aura is a little bit better than Osprey Ariel. The Aura is about a pound lighter compared to Ariel. And this weight difference is very crucial, especially during strenuous backpacking trips. Additionally, even though they are both incorporated with Osprey’s prominent anti-gravity technology, Ariel has a much bulkier suspension system, which makes it a little less convenient.

In-Depth Comparison – Osprey Ariel vs. Aura

Osprey Ariel

The Osprey Ariel backpacks are designed for people who are fond of extreme adventure trips. The Ariel series is perfect for alpine expeditions and trips that last more than a week. It has a heavy and durable design to help you bring all your gears.


What sets Ariel apart from most backpacks is its top lid and the front access zipper that can be converted into a day pack. Aside from having access to the main compartment from the top, it also comes with zippered access from the front or from either the sides of the backpack. Its top lid can be changed into a day-lite backpack so you can leave your hefty pack at the camping area and do some hiking throughout the day with your smaller backpack.

Anti-Gravity Suspension Technology

Osprey Ariel’s anti-gravity suspension technology has a larger frame and bulkier mesh in order to accommodate much heavier loads. With a wireframe that balances and lightens your pack and a mesh that hugs your entire back, it will feel like the backpack has a few fewer pounds.

Size Options

The Ariel series also comes in a wide variety of sizes. There’s a 75-liter, 65-liter, and 55-liter that comes in sizes medium, small, and extra-small. Ariel backpacks can carry heavier loads because of these higher capacity options. With a little bit more capacity options than Osprey Aura, you’ll have the right size for your adventures. Osprey Ariel also comes with very similar features, just like Aura, but with a few extras. These include:

  • An internal water reservoir sleeve

Osprey Aura

Similar to Osprey Ariel, Aura is also known as a universal backpack specifically crafted to fit women comfortably. This backpack is also famous for being one of the least straining and most breathable backpacks on the market.

Suspension System

Its best feature is its suspension system. Osprey thought of the anti-gravity technology over a decade ago, and the brand has been improving this technology since. This backpack is renowned for being the most ventilated pack in the market incorporated with a mesh back, which is suspended from the pack with a wireframe. This feature also makes the Aura feel more balanced and lighter.

The 65-liter pack weighs around 4.2 to 4.4 pounds, and the 50-liter pack is around 4 to 4.2 pounds. The weight will depend on the size you’ll get, which are medium, small, and extra-small.

Can the Osprey Ariel or Aura Fit As a Carry-On on a Flight?

Unfortunately, not all sizes can fit as a carry-on. In particular, the Osprey Aura 50-liter will surely fit as a carry-on pack on a flight. However, the Ariel 55-liter may not be able to do so because it’s a heftier pack compared to Aura. Regardless, you can try and check the dimensions with your preferred airline to see if you can fit your pack as a carry-on on a flight.

Are These Packs Safe to Check As Luggage On a Flight?

Of course, you can check any size of both Osprey Ariel and Aura, but make sure you are careful with your pack’s buckles and straps. We suggest getting the Osprey Airporter so you can cover your bag during flights and to prevent your pack’s buckles and straps ripping off in airport machinery.

Why Is It Called “IsoForm 5” Hip Belt?

Unlike the fit-on-the-fly hip belt, the IsoForm 5 is an older technology. It’s a detachable hip belt that can be replaced with a standard-sized hip belt. IsoForm 5 hip belts also adapt to the user’s body shape by being heated up in a certain oven at your local Osprey shop and buckled around the waist while they are cool.

Is There a Rain Cover Included In Ariel and Aura Packs?

Rain covers are not included upon purchase. However, you can buy the right rain covers separately by heading to Osprey’s website. You can also find some in your local Osprey dealer.

Are Osprey Ariel and Aura Packs Waterproof?

Both of these packs are not completely waterproof. They are only water-resistant since they are made of Nylon. The contents of your pack should remain dry if it only gets a splash of water. However, your gears might get wet if too much water gets on you while hiking or camping.
