The newly updated Osprey Aether 85 pack offers a lightweight mountaineering design, custom moldable hipbelt and a streamlined profile for backcountry pursuits.

  • Removable IsoForm CM™ (Custom Moldable) hipbelt offers superior load support with dual-density foam for enhanced support and an anatomically contoured shape
  • Osprey-certified Custom Molding available in most stores—check your local REI store for a custom hipbelt molding oven
  • ErgoPull™ hipbelt closure provides extra leverage in cinching, drawing tension along top and bottom—not through the center—to relieve hipbone pressure
  • IsoForm dual-density foam harness with spacer mesh promotes airflow and wicks away moisture during warm weather and intense activity
  • LightWire™ suspension uses peripheral rods, a nubbed foam back panel, single stay and an internal framesheet
  • Running down the sidewall, the peripheral rods anchor to load lifters and hipbelt, actively transferring load and resisting sag
  • HDPE framesheet protects your back from bulky or pointy items and supports heavy loads
  • Top pocket can be removed and converted into a lumbar pack; IsoForm hipbelt on pack can be removed and slid onto lumbar pack for comfortable carrying
  • J-zipper panel access makes packing and accessing your gear a breeze
  • Externally accessible bottom compartment with wide mouth and divider accommodates all types of sleeping bags
  • Dual-entry, stretch-woven side pockets keep essentials easily accessible, and a stretch-woven front pocket with welded vent accepts Osprey AddOns™ (sold separately)
  • Straightjacket™ compression with 3 horizontal straps let you securely compress the contents whether full or nearly empty, and without sag or load distortion
  • Internal compression strap stabilizes the load
  • Stow on the Go™ trekking pole attachment, side gear straps, ice axe tool loops, cord loop attachment slots and sleeping pad straps accommodate a variety of alpine gear
  • Hydration-compatible design features reservoir sleeve and dual drink tube exit ports for on-the-go hydration (reservoir sold separately)
  • Osprey Aether 85 pack shaves weight yet remains tough with a 210-denier double-ripstop nylon and 420-denier nylon packcloth body and 500-denier plain-weave oxford nylon bottom

Osprey Aether 85 Packis rated4.0out of5by4.
Rated4out of5byfromI'm likin' itI've used this pack twice so far on training hikes of 8-10 miles (getting ready for Philmont). Belt & suspension harness were comfortable carrying 35-40lb. loads. Plenty of room in the main compartment to swallow clothes, gear and rations. I like the removable top lid with hip belt. I do miss having gear pockets on the hip belt and shoulder straps, side pockets and forward leaning water bottle pockets I had on my previous pack but I'm adapting. This is a good quality extended-hike pack with good features but few frills.

Rated4out of5byfromGreat PackI love everything about this pack except for the hipbelt, which actually is great because it is moldable, I simply have not had chance to have mine molded. I've used this on multiple weekend trips and it has more than sufficient space for everything. I packed my bear canister, 0 degree bag, tent, pad, DSLR and a ton of accessories into this pack with room to spare. All the small accessories needed quickly can fit into the top of the pack well with easy access. There are also plenty of external straps to accomodate everything including a tripod. I highly recommend this pack!

Rated3out of5byfromDurable but difficult to organizeUsed for four shakedowns and ten days at philmont. Good pack, durable, good adjustments for hip belt and shoulder straps. Held a lot of weight without feeling too heavy. Lower zipper (sleeping bag) was difficult to close as it zips on a turn. Few outside pockets and no internal separator a made this pack difficult to organize. Top pocket was good size. When looking there seemed to be a trade off of weight and ease of use. This pack was in the middle. I was happy with the choice.

Rated5out of5byfromGreat PackThis pack is easy to fit and very comfortable. It has held up to 60 pounds for me and was really comfortable. It is easy to adjust weight distribution from hips to shoulders. It holds a lot and can cinch it down with all the compression straps, but also can expand to hold a ton. Plenty of pockets and easy access. You might want to get the rain fly because it will leak if you're stuck in rain for an extended period of time or in a downpour. Well worth the money and durable.
