Never say it can’t be done. After removing the guardrails of traditional manufacturing technologies, the Osprey UNLTD Series was born. Designed by Founder Mike Pfotenhauer along with Osprey’s innovation team, the Women’s Osprey UNLTD AntiGravity 64 is an industry game-changer. A women’s-specific torso, harness and hipbelt ensures maximum efficiency, comfort and safety, while a groundbreaking 3D Printed Fitscape™ Lumbar with Carbon DLS™ Technology provides superior ventilation, fine-tuned support and anti-slip grip. A clever AutoLift System automatically adjusts the harness length while a Fit-On-The-Fly® hipbelt allows for fine-tuned adjustment on the go. Featuring a clamshell design and anodized 7075 aluminum frame. This limited-production pack is made from state-of-the-art fabrics with included premium raincover, custom Airporter transit cover and convertible top lid lumbar pack.
