Aether Pro 70L Backpack

Conquering steep rocky pitches on day two of your solo-backpacking trip into the Cascades might be daunting to some, but with your know-how, strength, and Osprey Aether Pro 70 Backpack you feel downright unstoppable. This pack falls as far into the "featherweight" category as a 70-liter can, weighing in under 4lbs (size medium), so you can pack in all of your necessities without being weighed down. It features the newly reworked back panel and Lightwire Suspension system that makes heavy loads feel more manageable while you dive deeper into the backcountry by using a lightweight aluminum frame to transfer your load to your hip belt, alleviating pressure on your shoulders and back while you pick your way through overgrown trails to the next valley where you'll spend the night.

To make sure you're fully prepared for whatever adventure you choose, the pack is equipped with ample straps for carrying sleeping pads, trekking poles, and ice tools, so you're not limited with your choices. An internal pocket offers space to add up to a 3-liter reservoir for added hydration, and pockets at the hip belt give you quick access to your maps and snacks. On back you can add an additional Osprey Daylite pack or Alpine Pocket, so you can go for quick out-and-back day hikes once you've set up your base camp, without the need for lugging your whole pack along on the trip. If you're going for streamlined, the Aether has the answer for you with a removable top lid, removable ice tool loops, removable side compression straps, and removable sleeping pad straps, so you can shed weight as needed, while still carrying the gear you need for an overnighter or weekend expedition.

  • A light and fully loaded pack for backcountry excursions
  • Lightwire suspension transfers weight to hip and breathes
  • Let fresh air in to keep you cool with Airscape back panel
  • Isoform4 harness and hip belt molds to your body for comfort

  • Compression straps on side and back slim down your load

Pro- level minimalism

I've used it once or twice and have initial impressions

I stripped this pack down to the bones for an overnight trip attempting to summit a peak near SLC. One of the great things about this pack is your ability to remove the hip pockets, brain, and hip belt. I kept the hip belt, but removed everything else, I was only going on an overnighter and wanted to be able to move fast and light through winter conditions. This pack was perfect. It shed snow easily, was comfortable the entirety of the trip, and offered plenty of space for the winter gear I took. There are a bunch of minimalistic lashing and attachment points on this bag. I used them for an Ice axe, a small daypack, and trekking poles, while my buddy had a z-pad and tent on the outside. The design would have allowed either of us to add many more tools and gear to the outside if needed.

Simplicity is key.

I've used it several times

This pack is great. Some of it's best features are the ability to shed the top and side pockets/pouches. The belt and frame are also extremely simple and easy to use, although the pack on it's own seams to be a little heavy for a pack without AG. The extra lb of the pack is definitely made up for by the level of comfort it provides when the pack is loaded heavy, and the compression straps work so nicely. The adjustability is fantastic in the pack, and it's nice to be able to have organization without all the bells and whistles. I think I'd have to say my one concern is that the pack is pretty tall, and there is only one opening at the top. Otherwise, it's amazing!

Everything you need. Nothing you don't

Chck it out - a phenomenal, strippable load hauler for the pro (or those of use who want to be one!). Leta Osprey Rep

Fits Amazingly

I've used it once or twice and have initial impressions

I loved how well this pack fit and how easily it would conform to my body just minutes into the hike. We did 40 miles in the Wing River Range and this pack made the hike seem easy! After throwing the pack on and starting the hike this pack would adjust to my body and made the heavy load ride really well. The different ways it can adjust and the simplicity of the design made it easy to adjust on the fly. It also packs really efficiently. Several times on the hike i was complimented on the pack and how well "stacked" it seemed to be. Overall loved this pack and have been recommending it to everyone who's in the market for a sweet pack that can carry larger quantities and still fit comfortably.

Minimalist and durable pack

I've used it several times

The Aether Pro won't be the pack for those just getting into backpacking but for the seasoned Pro who doesn't need or want all the bells and whistles, and weight associated with them. It's top load only which very few pockets. That keeps the weight down. The Aether Pro is the Men's, the Ariel Pro is the Women's version of this pack. Want all the bells and whistles? Go for the non-Pro Aether or Ariel instead. There are plenty of straps and attachment points to add additional gear to the outside. In the photo I had my tent on the outside along with my trekking poles as I didn't need them at the moment. If you don't want/need those straps you can optionally remove them to lighten your load even more. Compatible with both the Daylite and Daylite Plus daypacks. Those clip right on for added storage and for use as a daypack or summit pack. The tent attached is a Big Agnes UL3 HV . The photo was taken in the Zion Narrows.
