One of the reasons that you ditch your desk and head into the wilds is so you can get a chance to move. And just because you're strapped to a pack doesn't mean you should be tied down by it. The Black Diamond Sonic Backpack adapts and moves with you so you have full freedom of motion for quick sprints and challenging alpine routes where you need your arms to safely navigate the way.

  • SwingArm tech routes the shoulder straps through the pack's lumbar area where they connect and free-pivot, thereby freeing shoulder and arm movement
  • V-Motion frame utilizes an anatomically contoured frame to efficiently transfer weight to your hips
  • Zippered panel access helps you organize and gain access to your gear more readily
  • Side stretch pockets house on-trail necessities
  • Retractable trekking pole loops can also accommodate an ice ax
