Osprey Mira 32

Osprey says:
The women's-specific Mira 32 is a quality hike hydration pack that comes with premium features to match the importance of your outdoor pursuits. A sizable main compartment stores all that's needed for a long day hike, or even a supported overnight. (Hello, bucket list hut-to-hut hike!) An integrated 2.5-liter reservoir and raincover ensure from the start that you never go thirsty and your pack stays dry. AirSpeed suspension and an adjustable harness deliver a comfortable and custom fit, while a highly ventilated 3D-tensioned backpanel offers excellent air flow. Front, side, and hipbelt pockets keep everything in its place and our Stow-on-the-Go attachment system lets you store trekking poles directly onto the pack in seconds.
