We'll get right to the chase because the Osprey Women's Ariel 65 Technical Pack - XS/Small has a ton of features! It comes with a convenient front panel with zip access to the spacious main compartment that includes a hydration reservoir sleeve. On the exterior, you'll find a fabric-reinforced front shove-it pocket, large stretch mesh water bottle pockets on the sides, dual upper and lower side compression straps, and two front panel StraightJacket compression straps. The floating top lid gives you some extra room and includes lash points to attach smaller gear. An injection-molded, die-cut foam AirScape backpanel creates a breathable and close-to-body fit. Finetune the hipbelt, shoulder straps, and adjustable torso length for a custom fit that's all your own!
