Choose the women's-specific Osprey Ariel 55 when you plan on traveling light, but still need enough room for a week's worth of food and camping equipment.
The heat-moldable IsoForm CM hipbelt and harness blend cushioning and firmness to create a customized, comfortable fit, while the LightWire frame transfers weight from your spine to your hips. Dual side compression straps secure your load while the Airscape mesh backpanel keeps you dry even when you're pushing hard uphill.
The main compartment is accessible via a large top opening or a front J-zip so you can find gear quickly. A separate sleeping bag compartment keeps your bag compressed and out of the way. The top lid converts to a lumbar pack for quick trips from camp. And if you need additional volume, Osprey's Daylite daypack (sold separately) attaches to the exterior via reinforced loops.
Stretch mesh side pockets and zippered hipbelt pockets give you plenty of easy-access storage options and the backpanel hydration sleeve makes liquid refills a breeze. The Stow-on-the-Go trekking pole attachment, ice axe loops, and removable sleeping pad straps provide plenty of secure external gear storage options.
