The Osprey Ariel Women’s 55 pack strikes an excellent balance between lightweight design and load-bearing performance. Ideal for long weekends or multi-day backpacking trips, the Ariel 55 offers over 2900 cubic inches of storage capacity and comfortably carries up to 60 pounds!

Constantly striving to enhance comfort and performance, Osprey has equipped the Ariel 55 with a LightWire aluminum alloy peripheral frame and a recycled HDPE framesheet. A single vertical aluminum stay further bolsters the Ariel 55's load-bearing capability. This design ensures your balance by effectively distributing weight. A textured, foam Airscape back panel and Women's IsoForm harness maximize comfort and help to reduce heat build-up between your back and the pack. Further enhancing fit, the revolutionary Women's IsoForm CM hipbelt utilizes an ErgoPull closure that draws tension along the top and the bottom of the belt. A sliding sternum strap and load-lifter straps allow you to fine-tune fit with on-the-go adjustments. Each of three available sizes of the Ariel 55 offers torso adjustability. The X-Small accommodates torso lengths ranging from 14"-17", the Small accommodates torso lengths ranging from 16"-19" and the Medium is designed for torso lengths that exceed 19".

To further guarantee that the Ariel 55 fits like a glove, Osprey's Women's IsoForm harnesses and IsoForm CM hipbelts are swappable. The XS hipbelt fits waists less than 28", the S hipbelt fits waists ranging from 27"-31", the M hipbelt fits waists ranging from 30"-34" and the L hipbelt is designed for waists larger than 33". The Ariel 55's IsoForm CM harness is also available in four sizes. Each size of the harness provides a vertical adjustability of 2"-3". NOTE: For most backpackers, the shoulder harness size should match the selected pack size, but for those with wider or narrower shoulders, choose one size up or down for the best fit.

The Ariel 55’s packbag is top-loading, but a sleeping bag compartment offers lower, front access. Additionally, a zipper on the front of the pack allows quick access to the main packbag. A large front pocket utilizes welded stretch woven Nylon fabric to serve as a convenient storage spot for layers of clothing or other gear. Elastic side pockets are the perfect place for stashing water bottles or other smaller items. Integrated hipbelt pockets provide a spot to keep essentials close at hand. Side compression straps enable you to cinch down your pack to keep contents safely and securely in place and also double as lash points for additional gear. Buckled straps that pass over the front of the packbag are designed to further enhance the compressibility of the Ariel 55 and provide yet another place to lash gear.

Other features found on the Ariel 55 include integrated trekking pole loops and a top lid that is removable for use as a lumbar pack. Removable straps located in front of the sleeping bag compartment securely stow sleeping pads. An external sleeve tucked behind the Airscape back panel makes the Ariel 55 hydration system (sold separately) compatible without eating into any internal capacity.
