The Osprey Aether 70 strikes an excellent balance between lightweight design and load-bearing performance. Ideal for multi-day backpacking trips, the Aether 70 offers 4000+ cubic inches of storage capacity and comfortably carries up to 60 pounds!
Constantly striving to enhance comfort and performance, Osprey has equipped the Aether 70 with a LightWire aluminum alloy peripheral frame and a recycled HDPE framesheet. A single vertical aluminum stay further bolsters the Aether 70's load-bearing capability. This design ensures your balance by effectively distributing weight. A textured, foam Airscape backpanel and IsoForm harness maximize comfort and help to reduce heat build-up between your back and the pack. Further enhancing fit, the revolutionary IsoForm CM hipbelt utilizes an ErgoPull closure that draws tension along the top and the bottom of the belt. A sliding sternum strap and load-lifter straps allow you to fine-tune fit with on-the-go adjustments. Each of four available sizes of the Aether 70 offers torso adjustability. The Small accommodates torsos ranging from 16”-18.5" in length, the Medium accommodates torso lengths ranging from 18"-20.5", the Large accommodates torso lengths ranging from 20”-22.5” and the XLarge is designed for torso lengths that exceed 22".
To further guarantee that the Aether 70 fits like a glove, Osprey offers swappable IsoForm CM hipbelts and shoulder harnesses. The S hipbelt fits waists ranging from 27"-31", the M hipbelt fits waists ranging from 30"-34", the L hipbelt fits waists ranging from 33"-37" and the XL hipbelt is designed for waists larger than 36". The Aether 70's IsoForm CM harness is available in four sizes. Each size of the harness provides a vertical adjustability of 2"-3". NOTE: For most backpackers, the shoulder harness size should match the selected pack size, but for those with wider or narrower shoulders, choose one size up or down for the best fit.
The Aether 70’s packbag is top-loading, but a sleeping bag compartment offers lower, front access. Additionally, a zipper on the front of the pack allows quick access to the main packbag. A large front pocket utilizes welded stretch woven Nylon fabric to serve as a convenient storage spot for layers of clothing or other gear. Elastic side pockets are the perfect place for stashing water bottles or other smaller items. Integrated hipbelt pockets provide a spot to keep essentials close at hand. Integrated hipbelt pockets provide a spot to keep essentials close at hand. Side compression straps enable you to cinch down your pack to keep contents safely and securely in place and also double as lash points for additional gear. Buckled straps that pass over the front of the packbag are designed to further enhance the compressibility of the Aether 70 and provide yet another place to lash gear.
Other features found on the Aether 70 include integrated trekking pole loops and a top lid that is removable for use as a lumbar pack. Removable straps located in front of the sleeping bag compartment securely stow sleeping pads. An external sleeve tucked behind the Airscape backpanel makes the Aether 70 hydration system (sold separately) compatible without eating into any internal capacity.
