Osprey Ariel Plus 60

Osprey says:
A reliable women's-specific pack that goes the extra mile when needed, the Ariel Plus 60 is ready for anything Mother Nature throws its way. The Custom Fit-On-The-Fly Hipbelt and Shoulder Strap allow you to dial in the perfect fit and a close-to-body carry stabilizes the load when the trail turns technical. The top lid detaches and converts into a daypack for side excursions. Constructed with high quality bluesignA(R)-approved high-tenacity nylon and PFC-free DWR.
