Amber 68
Gregory
The Gregory Amber 68—the updated high-capacity model in Gregory's core backpacking line—is built for extended backcountry routes and gear-intensive itineraries. It is aimed at women needing a large-volume hauler with a simple, forgiving adjustment system that can manage bulky multiday loads without unnecessary mechanical complexity. The pack relies on the VersaFit suspension system, which couples an adjustable torso length with an alloy Wishbone frame. The harness height adjusts along a continuous hook-and-loop panel, connecting directly to breathable 3D foam back padding. The frame transfers weight effectively into a wraparound, padded hipbelt. While it does not offer the dynamic pivoting articulation of the top-tier Deva, the Amber provides a dependable, close-contact carry that keeps heavy gear stable and centered. At 68 liters, the pack accommodates bear canisters, bulky synthetic sleeping bags, and multi-day food rations easily. It features a lower zippered compartment, dual mesh side water bottle pockets, a front stretch-mesh pocket, and an integrated raincover. The trade-off is standard foam ventilation; without an elevated trampoline mesh screen, your back will run warmer during hard climbs. For broad capacity and straightforward durability, it delivers honest multiday performance. **Highlights** - VersaFit adjustable torso system with breathable 3D foam backpanel - Wishbone alloy internal perimeter frame for heavy load stability - Generous 68-liter capacity suited for extended multiday itineraries - Dedicated sleeping bag bottom compartment with removable divider - Front stretch-mesh pocket for quick outerwear storage - Included custom-fit raincover stowed in a dedicated zippered pocket **Watch-outs** - Close-contact foam backpanel offers less ventilation than trampoline mesh packs - Hipbelt is fixed to the frame without dynamic swivel or rotation joints - High volume can encourage overpacking if base gear is already compact

Aura AG 65
Osprey
The Osprey Aura AG 65 is built for backpackers prioritizing cooling airflow and a continuous wrap around the back and pelvis. Its signature AntiGravity suspension integrates a seamless sheet of suspended mesh from the upper shoulder blades down through the lumbar area and hipbelt. This construction distributes contact evenly across the back, eliminating the localized pressure points that often form around traditional foam lumbar pads. In practical use, the AntiGravity system delivers exceptional ventilation in warm conditions, but its continuous tensioning creates a distinct fit profile. Because the hipbelt naturally curves inward under spring tension, putting the pack on requires physically spreading the hip fins open. This design works exceptionally well for hikers whose pelvic geometry aligns with the pre-curved shape, but it can exert excessive inward pressure on wider hip profiles. A loaded fitting is critical to verify that the lumbar curve seats properly against your lower back without pushing your hips forward. Structurally, the pack balances durability with multiday organization, offering deep stretch-mesh side pockets, dual zippered front pockets, and a floating top lid that can be removed and replaced with an integrated fabric FlapJacket cover. The tradeoff is overall pack weight and bulk; the internal perimeter frame and suspended mesh structure add mass before gear is packed. **Highlights** - AntiGravity continuous suspended mesh backpanel and lumbar wrap - Fit-on-the-Fly adjustable hipbelt and shoulder harness system - Removable floating lid with integrated FlapJacket cover - Dual front zippered utility pockets for rapid trail access - Stow-on-the-Go trekking pole attachment points - Lower sleeping bag compartment with removable internal divider **Watch-outs** - Spring-tensioned hipbelt requires deliberate effort to step into and can pinch broader hip profiles - Suspension frame adds noticeable empty pack weight compared to minimalist haulers - Deep frame curve slightly encroaches on internal main-compartment volume
