Key Considerations When Choosing Your Pack


Being able to customize your fit is essential for a comfortable hiking experience. Osprey encourages you to measure your torso from the C7 vertebrae to the iliac crest to see what size pack is best for you.

Most packs range from S to XL. From there, you have adjustability in both your shoulder straps and hipbelt to provide the most comfortable fit for long days on the trail. Check out this article for more in-depth info on sizing.


Whether you’re hitting your local trail for a casual day hike, taking on the Pacific Crest Trail, or somewhere in between, you’ll need different features in a pack to perform at your best. Longer thru-hikes require strategic packing and minimal pack weight while shorter treks allow for a little more wiggle room. 


When it’s all said and done, you need to be able to stay organized on the trail. The last thing you want is to have to pull all of your gear out in search of that one elusive item, and then figure out how to shove it all back in.

Utilizing the different pockets on your pack can save some headache, as well as the utilization of stuff sacks. You can utilize stuff sacks, dry bags, and packing cubes to keep your pack organized and your gear neat and easily accessible.

The Atmos and Aura AG are a continuation of Osprey’s bestselling pack series. They’re designed to take on a wide variety of hikes, up to a week or more. Best suited to a wide range of backpackers, this is a great option for the hiker who likes to bounce from casual day hikes to longer adventures and wants a pack that can take on those diverse trips.

These packs utilize the same framing and suspension tech as Exos and Eja, which allows for a two-size-per-gender fit. But the hipbelt construction differentiates the Atmos and Aura AG from the other packs.

The AG technology extends the tensioned back panel into the hipbelt and integrates the hipbelt overlay into the frame to decrease pressure and increase load transfer for a smoother carry. The customizable hipbelt and ErgoPull design provide a proper fit and adjustable weight distribution.

These packs are available in 50L and 65L capacities, giving you room for up to 40 pounds of gear.

Key Features:

Packing Right

Osprey focuses on thoughtful integration of where to place pockets, straps, and various storage solutions in its packs to make organization on the trail easy. A properly packed backpack can make all the difference between an amazing experience and a miserable one, so taking the time to research and practice your packing technique is always time well-spent.

Before you throw things in your pack, it’s best to lay it all out in one spot and run through a backpacking checklist. Once all your gear is ready, then you can concentrate on packing it with weight and accessibility in mind.
