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. 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.

The Osprey Aether 70 is available in your choice of size and color options.

Love this Backpack
Reviewed by Erin B. - May 7, 2017

Likes: very comfortable and easy to carry. holds a ton of gear but sits well on your hips and doesn't pull on your shoulders.

Dislikes: nothing so far

Very nice pack but to heavy
Reviewed by Michael B. - April 4, 2017

Likes: Very nice pack with lots of storage area. Has a really nice harness system.

Dislikes: It was bigger than I expected.

Great classic design pack; buy it, you won't be disappointed!
Reviewed by Steve F. - February 1, 2017

Likes: The Osprey Aether 70 is a classic design pack that will last season after season and works well in pretty much any backpacking stituation you find yourself in. Sure it's not the lightest pack in the world but things like the light wire peripheral frame and robust 4 point tightening belt system will carry loads heavy to light and never sag on you. The materials used to make this pack are all very high quality and are known to perform well.

Dislikes: There are minimal dislikes in my opinion. I do wish the hip belt pockets were bigger and that the stretch mesh side pocket were a little bit easier to access for the use of water bottles. I find them less than easy to access. But outside of that this pack is amazing.

Very good quality pack, the weight is great for a 70L load hauler pack. Very comfortable once you get the pack adjusted for your body...this pack seems to have a "sweet spot" that you must find. Very supportive structure that allows you to walk upright

Great over-night to week long pack
Reviewed by Joshua B. - July 14, 2016

Likes: The Osprey Aether 70 is designed to be a highly adjustable pack and Backcountry Edge is the only online or in-person store that will allow you customize the hipbelt and shoulder harness without buying additional parts. I am between sizes and originally bought a large pack at REI. After many adjustments I finally returned that bag and bought a medium with large waist and shoulder harness from Backcountry Edge. While some claim a larger pack, for those of us between sizes, helps with heavier loads. I feel the exact opposite. I have a few herniated discs in my neck and lower back and was able to comfortably carry a 50-60 lb pack as it felt more like a 25 lb pack. The pack is comfortable and transfers the weight directly to your hips without much, if any, stress to your shoulders. The pack is made from fairly durable material, my dog dragged it across some rocks during a break and the only thing that tore was the side mesh pocket, and that was minor. The pack is roomy, after taking it on an overnight family camping trip I wished I would have bought the Aether 60, so keep that in mind. I can fit everything I need inside of the pack (as well as my 7 year old daughter) to include: 2 sleeping bags, 2 sleeping bag liners, 2 sleeping mats (one horizontal on provided straps and one vertical), 3-person Kelty tent, Optimus crux and terra weekend cooking set, 6 packs of freeze-dried meals, Katadyn vario water filter, 4 shirts, 6 pairs of socks, and 2 pair of pants. The top is floating so you can use it to strap down overstuffed loads equally. The load lifter straps are great at pulling the weight close to your body to keep the pack balanced. It runs right against you back and the foam keeps you cool. The hipbelt pockets allowed me to hold snacks, chapstick, knife, and multi-tool. This is my first internal frame pack. I originally set out to buy a Kelty redwing 50 or coyote 80. What sold me on the Aether (no matter the liter size) was the comfort of the pack once it was on. While the Kelty promotes their PerfectFit system, I never seemed to be able to find a perfect fit. Price considered, on a tight budget the Kelty would be a great option, but it just doesn't carry the weight like the Aether pack seems to do. This pack will compress if you lighten your load during your trip.

Dislikes: No enclosed side or front pockets for organization. For me, enclosed side pockets similar to military packs are standard. I like having them for easy access to socks without having to dig through the pack. I think this was done on purpose to push you toward buying the Osprey Daylite Daypack. I almost bought one, but I had trouble attaching the daypack to the Osprey Aether in the store and opted to not get the extra bag. The top pouch could have more than one compartment. It is touted as a removable waist pack but lacks the organization I want in a waist pack. The J-shaped zipper on the front could be improved to a U-shaped zipper allowing easier access to the inside of the bag. I needed something that was close to the bottom and couldn't find it, partially because the front zipper doesn't open completely. The sleeping pad straps are rather short and I had to roll my military style sleeping pad tightly to get it attached. No daisy chain loops on the front. On my trip in the pack did slip some because I was sweating, it was 100+ in Texas. On the hike out I did not have this problem. Most of these dislikes are missing from the Aether 70 to save on weight and I can live without them.

A good, versatile pack
Reviewed by Chris H. - June 29, 2016

Likes: Multiple access points into main compartment. Hip belt is interchangeable for different sizes. Good pack size and weight for multi-day trips.

Dislikes: Several of the straps installed seem to be a bit longer than necessary. Might need to trim them a bit to keep them from being annoying. Just a nitpick, since you asked.

Great Fit
Reviewed by Chris - July 7, 2015

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 Inside Edge Member - March 15, 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 Member - January 12, 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!
