For an expedition size pack made with highly durable yet lightweight fabrics the Aether Pro does a good job. The capacity of the pack means that it has to be good for carrying heavier loads and it certainly ticks that box.   

Osprey says:

A tough yet light pack designed for adventures where dependability is key. Completely stripped down, streamlined and svelte, the Aether Pro 70 is made for type-two adventures that span days or months; alpine climbing expeditions with remote basecamps, or boundary-pushing long-distance hikes through unknown landscapes where the only trail is the one you make. With one zipper, minimal fuss and strengthened hardware, this pack provides worry-free dependability in the harshest of conditions.

Stripped down, lightweight for moving fast and getting the job done. The Aether AG Pro doesn’t just carry heavy loads well, it fits bodies of all shapes and sizes. These packs are built for those who appreciate efficiency and create their own specific systems of organization based on their unique needs, whether expedition mountaineer or explorer of points unknown.

Created with NanoFly™ fabric, a tried-and-trusted backsystem and an extremely efficient main compartment design, these packs are built for those who appreciate simplicity and are used to creating a backpacking system to suit their own needs. These are packs for expert backpackers.

Osprey's Aether Pro is a serious 70L expedition rucksack. Designed with lightweight, highly durable fabrics and stripped back to provide exactly what's needed for a long adventure. Obviously, with this kind of capacity the pack has to have a solid structure to make carrying a heavy load as comfortable as possible and it certainly manages this. Compression straps add versatility if you are going out with less kit in good conditions and most of the features are removable to allow you to strip it down further in these cases. 

The fabric used is a mixture of 200D, 210D and 315D which are all amazingly durable yet the pack doesn't weigh as much as you'd expect with this. After prolonged use on numerous expeditions this pack still looks in really good condition - certainly nothing a good clean wouldn't fix. The pack still has everything you'd expect for an expedition ready rucksack. It is hydration system compatible, has stowable ice axe loops, trekking pole attachments, secure rope carry system, removable lid, sleeping pad straps and compression webbing. The hipbelt pockets are large and secure so you can easily keep key items handy.

What A Pack !

This pack is amazing, I'm a bit of a gear junkie, and if I had to pick one from all the packs I’ve ever owned, this beautiful looking work of modern back-packing art stands firmly above the rest. Yeah it looks great, better than the pictures! The red, black and grey, stays on the outside, but of course this is more than just how it looks, the thing just works. Durability wise it's built like a brick sh** house, the main body material has gram for gram (or so they say)12 times the tear strength of steel yet it's very lightweight. Having the stays on the outside of the pack makes them field repairable, not that they will ever need it. Key areas are further reinforced. The only 2 zips on the pack are on the removable (replaceable) lid and removable hip-belt, this is a pack designed to last. There is no faff. Features are limited to keep the weight down, but it still has all the important stuff. I really like the hip-belt pocket, Osprey decided that one should have a zip and one simply cinched, this is a much better place for a water bottle than on the pack itself. The zip pocket also has a piece of plastic reinforced cord for quick stowing of walking poles but you could hang anything there. Nice compression system, removable sleeping mat straps, lash points on the lid, axe loops, there is a top cover if you ever remove the lid. It's all very well thought out, nothing that's going to break, add weight, but everything you need. One thing I've noticed is due to the hip-belt being removable and the lid being removable with both male and female buckle connectors, it's possible to make yourself a lumbar pack like I can with my Crown2. Comfort is the key here, what we are looking at is a 70+ litre pack that can handle 27.3 kg (60lbs). I would never go that heavy, nowhere near, but that's not the point, it's simply very comfortable no matter what you throw at it. Nicely padded, comfy hip-belt that can be heat moulded to your body if you take it to a outlet (time will do this anyway). Great shoulder straps, load lifters that really seem to work well. To sum if up, this pack is more comfortable than a pack I use to love from Lowe Alpine that weighed 3.4kg. This weighs in at just 1.8kg. You can strip it down to 1.5kg, what you are then left with is a bomber big sack with killer support that’s super comfy. I’ve owned so many packs I try not to think about it but I can easily single this out as the best pack I’ve ever owned.
