The Osprey Aether Plus 60 is a men's multi-day pack with 60 L total volume (58 L main compartment), built for longer treks of roughly six nights or more and rated to carry loads up to 27 kg. Its air-channel back system with adjustable torso length combines ventilation with support for heavier loads, backed by an internal frame and a padded hipbelt with pockets.
Main compartment access works three ways — top lid, front J-zip panel, and a bottom entry to a separate sleeping bag compartment — making packing more flexible. The pack has two zippered front pockets, stretch-mesh side pockets, a stow-on-the-go trekking pole attachment, and two ice axe loops, aimed at demanding multi-day routes rather than fast-and-light trips. It's built from durable 210D nylon with bluesign approval and PFC-free DWR, and Osprey backs it with a lifetime free-repair program.
At 2540 g, that's about 42.3 g per liter — the highest ratio in the compared Aether lineup, reflecting a build for long, heavy-load expeditions rather than minimal weight.
