The Osprey Atmos AG 65 is designed with comfort as a top priority, making it an ideal companion for long hikes and backpacking trips. Its innovative Anti-Gravity (AG) suspension system is the key to its exceptional comfort. This system distributes the load evenly across your body, making it feel almost weightless and reducing strain on your shoulders, hips, and back.

Additionally, the seamless mesh back panel contours to your body, providing unmatched breathability and support. This design helps keep you cool and dry, even during strenuous hikes in warm weather. Combined with the adjustable torso length, shoulder straps, and Fit-on-the-Fly™ hip belt, the Atmos AG 65 offers a truly customized fit that adapts to your body shape and size.

Tip: For optimal comfort, make sure to adjust the AG suspension system according to your torso length and use the load lifters on the shoulder straps to fine-tune the weight distribution.

Despite its robust construction and numerous features, the Atmos AG 65 remains relatively lightweight. The medium size weighs just 4.56 pounds (2.07 kg), making it a great option for those who want to minimize the weight they carry on the trail without sacrificing durability or functionality.

The Atmos AG 65 achieves this balance by utilizing high-quality materials and a thoughtful design that prioritizes weight savings where possible. For example, the backpack’s frame is made from lightweight aluminum, and the fabrics used are chosen for their strength-to-weight ratio.

A lighter backpack allows you to carry more gear or simply enjoy a more comfortable hike. However, it’s crucial not to compromise on essential features and durability for the sake of saving weight.

Osprey’s focus on providing a lightweight backpack without sacrificing essential features sets the Atmos AG 65 apart from some of its competitors. This balance makes it an ideal choice for backpackers and hikers who want to minimize their load without giving up the functionality and durability they need for their adventures.

Quick tip: When packing your backpack, try to optimize your gear selection to minimize weight. Choose lightweight, compact, and multi-functional items to help reduce the overall load you need to carry.

  • Gregory Baltoro 65: The Baltoro 65 is another well-regarded backpack with a similar capacity. It offers excellent comfort and durability but is slightly heavier than the Atmos AG 65. The Baltoro also comes at a higher price point. Also, don’t overlook our comparison on the Gregory Optic vs Octal.
  • Deuter Aircontact Lite 65+10: This backpack has a slightly larger capacity and comes with a more affordable price tag. However, it lacks some of the advanced features found in the Atmos AG 65, such as the Anti-Gravity suspension system and the Fit-on-the-Fly™ hip belt.
  • REI Co-op Flash 55: The Flash 55 is a lighter and more budget-friendly option. While it lacks the carrying capacity and some features of the Atmos AG 65, it’s a suitable choice for minimalists or those who prioritize weight savings above all else.

As Backpacker Magazine’s gear editor, Eli Bernstein, puts it: “The Atmos AG is the most comfortable pack I’ve ever worn.”
