Osprey Atmos AG 65 Review

The Osprey Atmos AG 65 revolutionized backpacking comfort with its groundbreaking Anti-Gravity suspension system. This innovative 3D-suspended mesh ventilation creates an almost weightless feeling even with heavy 40+ pound loads, making it our top choice for serious multi-day adventures.

Anti-Gravity Suspension System

The AntiGravity suspension is the star feature—a continuous run of 3D-suspended mesh that seamlessly connects the hip belt, back panel, and shoulder straps. Unlike traditional foam padding, this trampoline-like system distributes weight evenly while keeping the pack slightly off your back for superior ventilation.

Capacity & Organization

With 65 liters of space (available in 62L-68L depending on size), the Atmos handles everything from weekend trips to week-long expeditions. Eight exterior pockets provide excellent organization, including dual side zip access to the main compartment and a top lid that converts to a daypack.

Comfort & Fit

The Fit-on-the-Fly adjustment system allows four inches of vertical shoulder strap adjustment without tools. The hip belt offers six inches of adjustment, accommodating a wide range of torso lengths and waist sizes. Even with maximum loads, the suspended mesh prevents pressure points.

Durability & Materials

Constructed entirely from recycled materials with PFC/PFAS-free DWR treatment and bluesign approved fabrics. The robust build quality includes reinforced stress points and YKK zippers throughout. An integrated rain cover protects against weather.

Load Capacity & Performance

Rated for loads up to 40 pounds, the internal aluminum frame and fiberglass stays maintain stability even when fully loaded. The suspended mesh system actually performs better with heavier loads, as it creates more separation from your back for improved airflow.

Storage Features

Thoughtful details include Stow-on-the-Go trekking pole attachments, internal hydration sleeve, front stretch mesh pocket, and dual zippered hip belt pockets. The sleeping bag compartment with zippered divider keeps gear organized and accessible.
