The Osprey Ariel Plus 70 is the flagship of the women's Ariel Plus line, with 70 liters of capacity (68 l main compartment) and a weight of 2561 g. Its 27.3 l/kg volume-to-weight ratio places it among the mid-weight, fully featured packs built for demanding multi-day trips. The frame is a 3.5 mm aluminum LightWire peripheral frame with a padded contact back panel, chest strap, and load lifters.
The main compartment opens from the top lid and from the bottom, making it easier to pack a sleeping bag separately. The removable lid doubles as a standalone daypack for excursions from camp, so there's no need to carry the full load on shorter outings. One front and two side pockets round out the organization, and dual ice axe loops extend use beyond standard trails.
Construction uses 210D high-tenacity nylon with bluesign certification and a PFC-free DWR finish. The pack is hydration-compatible, includes an integrated rain cover, and carries a 99-year warranty. It suits women planning demanding multi-day treks who need to carry a heavier load while having a detachable daypack available for lighter side trips.
