From rolling forest trails to exposed ridge scrambles, the Black Diamond Sonic Pack is a streamlined, mid-sized daypack ideal for any long, active day out. This high-performance pack features our ergoACTIV suspension, which uses a custom 3D pivoting hipbelt and our SwingArmTM shoulder straps for complete freedom of movement.

WHY ACTIVE suspension?
Black Diamond packs built with our award-winning active suspension systems—ergoACTIV, ergoACTIV XP, reACTIV and reACTIV XP—are unparalleled in comfort, efficiency and load transfer. Because the shoulder straps and hipbelt move with you, friction and hot spots are eliminated. The pack’s load stays perfectly balanced at all times—without adjustment—and allows your body to move naturally in any direction. This results in a more efficient, comfortable, longer stride—meaning you can cover more ground, more quickly.
