For backpacking, thru-hikes and alpine expeditions, the Aether AG™ Series has a pedigree like no other pack. We set the bar for technical backpacking packs by combining Anti-Gravity™ technology with customizable fit and innovative features like our new convertible top lid to create a more capable and comfortable pack for long-haul load carrying on any multi-day excursion.When you need a pack that can carry heavy loads for up to a week or more, there is no better option than the Aether AG™ 70. Size XL comes with a Large hipbelt and harness.



The IsoForm5 harness and CM™ hipbelt provide outstanding fit and comfort for especially heavy loads and long miles. Both components are interchangeable to provide a truly custom fit.


The Aether/Ariel AG™ features a continuous, suspended panel of lightweight mesh extending from the upper torso through the lumbar area of the pack and wraps the user in supreme comfort.
