Osprey UNLTD AntiGravity 64 Backpack

This season sees the arrival of UNLTD: an industry-changing series created by Osprey. Following a two-year design journey, UNLTD represents true pack innovation.

Central to the series is the Carbon DLS technology. The first pack company to incorporate 3D printing into the pack build, Osprey use it to create their Fitscape lumbar. The technology allows for precise fine-tuning of cushioning, support, and ventilation while minimising manufacturing waste.

The innovation continues in the harness. As you tighten the shoulder straps, a new Autolift system automatically adjusts the pack’s position, distributing the load evenly for optimal carrying comfort. State-of-the-art fabrics raise the bar further, with Ultra-High Molecular Weight Polyethylene content maximising durability without a weight compromise.

UNLTD encompasses two models – AirScape 68 and AntiGravity 64, with tailored men’s and women’s versions available for each pack. Both deliver premium backpacking performance.

In the UNLTD AntiGravity 64 Men’s, a 7075 anodised aluminium frame and stainless steel hip tension springs provide a lively and flexible fit. Ready for multi-day treks, the 64-litre capacity and considered feature set enhance your hiking experience. Highlights include a removable top pocket that converts into a hydration-compatible lumber pack. A Deluxe Raincover fends off the elements, while the Deluxe AirCover protects when in transit or storage.
