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

Deva 60
Gregory
The Gregory Deva 60 is designed for multiday hikers who carry dense, demanding loads and need maximum frame support over technical terrain. Where lightweight packs rely on flexible framesheets, the Deva utilizes Gregory's FreeFloat A3 suspension, built around an alloy perimeter frame and an auto-rotating shoulder harness. This mechanical design allows the pack body to pivot dynamically with hip motion, stabilizing heavy kits without shifting off-balance. The back panel pairs 3D AirCushion mesh with a close-contact lumbar pad. This keeps the pack’s center of gravity close to the spine, delivering steady load transfer directly to the pelvis. Unlike trampoline-style packs that push the pack weight away from your back to maximize airflow, the Deva prioritizes absolute load control and trail balance. The trade-off is reduced back cooling on high-output uphill sections. The construction is heavily featured and robust. It includes a dedicated U-zip front opening for wide access to the main compartment, oversized hipbelt pockets shaped to fit modern electronics, and independent torso and hipbelt size customization. Hikers traveling with disciplined, lightweight kits may find the Deva overbuilt, but for extended routes requiring heavy food carries or winter layers, the structural support is purpose-built. **Highlights** - FreeFloat A3 dynamic suspension with auto-rotating shoulder harness - AirCushion mesh backpanel engineered for close-contact load stability - Full front U-zip access to the main compartment - Custom-fit 3D shoulder harness and hipbelt components - Oversized zippered hipbelt pockets for trail accessories - Hydration sleeve that doubles as a lightweight daypack **Watch-outs** - Substantial empty pack weight compared to lightweight multiday alternatives - Close-contact back panel retains more heat than fully suspended mesh designs - Extensive strap and pocket layout can feel overly complex for minimalists
