Black Diamond Onyx 55 Backpack - Women's



Show Description

This well-featured pack has room for all the amenities. All the components on the ergoACTIV XP suspension system work together. The SwingArm shoulder straps are linked at their lower ends by a low-friction cable that runs through the hipbelt. This allows them to maintain even loading across your shoulders as you walk or reach. The hipbelt has urethane elastomers to stabilize and dynamically transfer weight. It’s connected to the frame with a custom-shaped ball joint that allows it – and you – to move unrestricted in any direction. Finally, the 6mm aluminum frame enhances stiffness and load transfer, and a 20mm centre stay adds support and gives the back panel a contoured shape.

  • Suspension system is designed to suit women's proportions.
  • OpenAir back panel allows ventilation.
  • Top-loading with floating top pocket, plus front zippered access.
  • Waterproof taping on top and bottom.
  • Compartment divider for organizing options.
  • Hipbelt pockets hold power bars or pocket cameras
  • Side pockets hold water bottles.
  • Front and internal organizer pockets keep your stuff sorted.
  • Retractable trekking pole/ice axe loop.
  • Sleeping pad straps save space in the main pack.
