Osprey Aura 65 liter pack, Medium frame. I only carried it about 50 miles on the AT.
Description of it from REI: Shoulder harness and hipbelt are specifically cut and contoured to fit women comfortably
Updated AirSpeed™ suspension offers fully adjustable torso length and adjustable hipbelt fit
Shoulder harness adjusts over a 3 in. range for fine-tuned fit; new pad design with spacer-mesh contact surfaces and ventilated foam provides breathable, supportive cushioning
Hipbelt uses dual-density foam for improved support and spacer mesh for breathability; exclusive adjustment system lets you customize the fit while wearing the pack
Hipbelt pads extend up to 3 in. on each side for 6 in. total adjustment range
LightWire™ alloy frame creates low-profile air space optimizing balance and ventilation; 3D tensioned mesh back panel ensures excellent breathability and supportive fit
Large main compartment contains a hydration sleeve and reservoir clip (reservoir sold separately); zippered sleeping bag compartment underneath features a removable divider
Floating top lid features a large pocket and an under-the-lid mesh pocket
Front stretch woven pocket, side stretch-mesh pockets, zippered hipbelt pockets and 2 large front zippered pockets help organize gear for quick, convenient access
Pack exterior features removable sleeping pad straps, Stow-on-the-Go™ quick stash trekking pole attachment system and dual ice axe loops with bungee tie-offs
The Osprey Aura 65 pack is made with a lightweight yet strong 210- and 100-denier fabric set that offers excellent durability and less trail weight than heavier fabrics
The only flaw is a small hole in the front pocket that I put super glue on to keep it from fraying. The hole doesn't affect its function at all. Sells new for $249. I'll take $199 for it. Shipping included CONUS
