The Osprey Atmos AG LT 65 backpack has long been a favorite among outdoor enthusiasts. And now, Osprey has introduced a trimmed-down version for 2023 that cuts away weight without sacrificing performance. In this review, we'll take a closer look at the Atmos AG LT 65 and see how it stacks up against the competition.

Carrying Comfort

When it comes to comfort, the Atmos AG LT 65 doesn't disappoint. The AntiGravity trampoline-like mesh backpanel provides excellent support and hugs your body as you wear the pack. The hipbelt and shoulder strap padding offer exceptional comfort, and the sturdy metal frame transfers weight to your hips effortlessly. With a maximum weight capacity of 40 pounds, this pack is solid and can handle even heavier loads with ease.

Weight

Weighing in at just over 4 pounds, the Atmos AG LT 65 is relatively lightweight compared to other backpacking packs in its class. It cuts away a half pound from the standard model, making it a great choice for those looking to shed weight without sacrificing comfort or durability. However, it would be interesting to see Osprey introduce a true ultralight version with even thinner fabrics to further reduce weight.

Organization

The Atmos AG LT 65 features a streamlined design when it comes to storage. It offers two tall water bottle pockets, a large stretchy "shove-it" pocket on the front, and a single zippered access to the lid's expansive space. Additionally, it has two hipbelt pockets, which are great for storing small items like your phone, wallet, or snacks. While the organization is simplified compared to the standard Atmos, it still offers functional storage options.

Ventilation

One of the standout features of the Atmos AG LT 65 is its ventilation system. The AntiGravity suspension, combined with the mesh backpanel and shoulder straps, allows for excellent airflow, keeping you cool and comfortable even during strenuous hikes. The pack stays close to your body, ensuring a balanced and comfortable carry.

Weather Protection

The Atmos AG LT 65 is built to handle light moisture with its durable water repellent (DWR) finish. The pack's fabrics, including the body, base, and accent, are treated to repel water and keep your gear dry. Additionally, it comes with a rain cover that can be easily secured to protect your pack during heavy rain. Leaving the rain cover behind can save you some weight, but it's recommended to carry it if there's a chance of rain.

Build Quality and Durability

The Atmos AG LT 65 is a tough and durable pack that can handle rough terrains and demanding conditions. It features 210-denier (D) nylon fabric on the pack body and an even stronger 500D nylon on the base. This construction ensures the pack can withstand bushwhacking, sharp rocks, and other challenges without showing signs of wear. The build quality is excellent, with sturdy zippers and buckles and robust materials throughout.

Fit and Sizing

The Atmos AG LT 65 comes in two different sizes, and the S/M size offers a great fit for torso lengths ranging from 16 to 21 inches. The pack features adjustable shoulder strap height and hipbelt padding, making it easy to customize the fit to your liking. The shoulder strap padding isn't adjustable, but it doesn't affect the overall comfort. The waist size range is not specified by Osprey, but based on the adjustable padding and the length of the hipbelt straps, it seems to be quite versatile.

Sustainability

Osprey has made sustainability a priority in their designs, and the Atmos AG LT 65 is no exception. The pack is made with recycled and bluesign-approved nylon, ensuring safe materials and practices that are friendly to the environment. The durable water repellent (DWR) coating is also PFC- and PFAS-free, further reducing the pack's environmental impact.
