Men's Osprey UNLTD™ AntiGravity 64

A blend of aluminum and stainless steel is used to achieve a performance range that's impossible to accomplish with a simpler solution. The spring steel works with the stiff aluminum frame to create the flex needed for a lively fit.

• No need to adjust and readjust load lifters while hiking. AutoLift automatically engages the upper frame of the pack, keeping the load close to back, stable and in proper balance.
• Works directly with CamLock Torso Adjustment System to quickly set the optimal position for shoulder straps.

• Blends multiple components perfectly to create optimal performance.
• The main tubular anodized 7075 aluminum alloy frame element provides outstanding vertical stiffness to resist collapse under load and maintain tension on backpanel mesh.
• Two horizontal stainless steel wires at the bottom of the frame deliver spring tension to the hipbelt area, controlling flex and fit.
• A pair of custom-molded hubs join the tubular aluminum and stainless steel wire elements together at the lower corners of the backpanel, allowing each material to offer its unique performance advantage independently.
• Additionally, the injection-molded hubs are exposed through the fabric at the bottom of the pack, providing a buffer and preventing wear when it is set on the ground, the hard nylon material can tolerate a lot of abuse without any issues.

• Micro-adjustable self-locking cams allow torso length to be quickly and easily adjusted to a perfect fit while the pack is worn.
• Simply lift up on the buckle lever to release the webbing and adjust the shoulder harness upward.

• Advanced 3D printing technology delivers a uniquely supportive lumbar pad.
• Flex and shape are tuned to support load evenly and reduce pressure points.
• Open structure ventilates and reduces heat buildup.
• Polymer compound grips securely to promote load transfer and eliminate slippage.
