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.

Great Fit

Likes: I love the ability of the different sizing options. The pack sits well on the hips and keeps the weight centered.

Dislikes: None so far.

Reviewed by Chris - July 7, 2015

Likes: After a seasons use, I would buy again. Weight distributed nicely on back makes hikes enjoyable. Exterior arrangements allows items to be easily reached hiking or resting.

Dislikes: Doesn't store compacted when not in use perhaps will become easier after many years of use.

Reviewed by Inside Edge M. - March 15, 2015

Likes: I liked the solid constuction, materials & zippers and ability to make adjustments using the multiple straps. However I realized it was too big for my needs and am exchanging it for an Aether 60, which Backcountry Edge promptly shipped to me.

Dislikes: No negatives at all!

Reviewed by Inside Edge M. - January 12, 2015

Likes: Perfect Size for me. I wish I would have got this sooner.

Dislikes: Nothing so far

Likes: Osprey makes amazing stuff and the aether series is the pinnacle of this. Amazing backpack with plenty of space for everything you need plus the durability to stand up to years of abuse.

Dislikes: Nothing

Likes: I love this bag. Its lightweight, and has just enough features. The J shaped access zipper on the front is crucial to get out a clean shirt or socks when my pack is full. Good compression straps, the side mesh pocket straps can be routed through the pocket or outside of it. The floating lid is nice and has a hip belt stashed on the underside so you can detach and take on day hikes. I purchased the Osprey Daylite pack which attaches to the front of the aether when I'm hiking in. This feature alone has been awesome. I even went to my local REI and had them mold the hip belt which has been great for distributing the load better across my hips.

Dislikes: nothing at the moment. In general it would be nice if apacks had more of a structured hydration sleeve. On longer hikes it is a pain getting a refilled bladder back into a full pack.

Reviewed by Fielding H. - June 5, 2014

Likes: I tested this pack on an 11 mile up and back shakedown with a 2000' gain. It is my 6th pack. I am 6'4" and 250 lbs. I carried 36 lbs. up. It was so comfortable, I didn't even drop the back for breaks. It felt like I was only packing 20 lbs.
The belt is amazing. It makes such a huge difference on how the load carries.

Dislikes: Nothing. It is worth every penny.

Dislikes: nothing i dont like about this pack

Reviewed by Anonymous Backcountry Edge Customer - May 12, 2014

Likes: This is one of the most comfortable packs you can get! The harness and hipbelt are second to none. I got the red one and I love the color. It also seems very durable

Dislikes: The one thing I wish it had were a couple more outside pockets for small gear like maps, compass, etc. Other than that, I am completely happy and look forward to hitting the trails real soon with this pack!

Reviewed by Inside Edge M. - March 29, 2014

Likes: The comfort in this backpack is exceptional. From the moment you put it on your ready to hit the trail. I had the generation before this and the upgrades have made it even that much better. Easy access to pockets, convenient trekking pole or ice axe holder to free up your hands, straps are easy to locate and adjust without taking the pack off, and light weight compared to other packs with the same amenities.

Dislikes: Nothing
