Osprey Aether Plus 60

Osprey says:
More than an all-around backpacking pack, the Aether Plus 60 is at home whether you're spending a week on the trail or heading off on a gear-intensive weekend. A stable, close-to-body carry makes this pack ideal for managing heavier loads over technical terrain. A custom Fit-On-The-Fly Hipbelt and Shoulder Strap offer a fine-tuned fit while a detachable top lid converts into a daypack. Constructed with high quality bluesignA(R)-approved high-tenacity nylon and PFC-free DWR.
