Featuring our reACTIV suspension and a spacious interior capable of swallowing a full day's worth of gear, the 26-liter Black Diamond Sonar pack is ready for summit scrambles, loop hikes and any other on- or off-trail day of adventure. The Sonar's high-flow OpenAir backpanel, shoulder straps and waistbelt keep your back cool and well ventilated during hot, sunny days. We designed the Sonar with a slew of organizer pockets, including a fleece-lined pocket for your phone or MP3 player and a raincover pocket (raincover not included) if the weather gets foul.

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.
