Designed for backpackers who prioritize both weight savings and functionality, Osprey adjusted their classic Aether 70 pack into a lighter and more streamlined version in the Pro. At 3.81lbs, it offers an impressive weight-to-volume ratio that doesn’t sacrifice the durability and quality that Osprey is known for. Key Features:

• NanoFly® – Osprey combined 210D nylon and a special polyethylene ripstop to create an abrasion-resistant fabric that is super lightweight.
• Removable Lid – Save even more weight on trips by removing the lid and covering the top of the pack with the included FlapJacket to protect gear.
• Add Volume Easily – The Aether 70 has reinforced loops that allow for attaching an Alpine Pocket or Osprey Daylite® daypack for additional gear space, or an extra option for shorter day trips.
• Stow-on-the-Go™ – This trekking pole stow system provides a quick spot to put poles if they need to be stashed briefly when needing your hands free or on steeper terrain.
