Osprey Aether Plus 70

Leaning toward expeditions, the Aether Plus 70 is the big brother of the Aether 65: a 3.5 mm LightWire hoop frame, a 210D high-tenacity nylon body and Custom Fit-On-The-Fly hipbelt and shoulder straps that are adjusted to the wearer. Its floating lid detaches into a DayLid daypack, and a front-panel zip opens the main compartment without unpacking from the top. At 6.2 lbs in L/XL it trades weight for load control, and the same chassis scales to 85 and 100 L versions rated for 40-70 lbs.

The Atmos AG 65 is Osprey's flagship men's backpacking pack and the best-known application of its AntiGravity suspended-mesh suspension. The current generation adds more hipbelt padding, easier main-compartment access, and an included raincover. The women's equivalent is the Aura AG 65.

The Aether 65 is Osprey's heavy-hauling workhorse, built around a burlier frame and tougher 420-denier fabric than the Atmos. It trades the AntiGravity trampoline for a body-hugging AirScape back panel that handles 50+ lb loads with more control. The women's equivalent is the Ariel 65.

The Ariel is the women's-fit Aether, Osprey's heavy-haul pack. It uses a contact back panel rather than suspended mesh, trading the Aura's airflow for load control, and a 420HD nylon packcloth shell that is the most durable fabric Osprey puts on a trekking pack. It is the women's pack in the line for loads above 40 lb.

Osprey Atmos AG LT 65

The Atmos AG LT is the lighter reworking of Osprey's flagship Anti-Gravity pack. It keeps the suspended-mesh AirSpeed backpanel that made the Atmos famous but swaps the sliding harness for five fixed torso positions and drops to a 210D recycled honeycomb shell, saving around half a pound over the standard Atmos AG 65 and $50 off its price.
