WHY ACTIVE suspension?

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.

Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by Comfortable and bombproof This is an awesome mid sized pack. I took it up Mt Whitney for a two day trip and it fit 40 lbs of gear more than comfortably. The loading system made it easy to get to get to all of my gear and the zippers move easily, never getting snagged. The suspension system is the best I have ever used, keeping the pack straight on my back no matter how crazy the trail got. The hip belt felt nice and snug and the initial adjustment to my back was all that was needed. I highly recommend this pack to anyone! December 25, 2014
Rated 5 out of 5 by Awesome Pack Used this pack to trek around Japan for two weeks. Felt very good on my back, and the front zips made it easy to organize and get things from it. Will use it on all my adventures and would recommend it to anyone. May 14, 2014
Rated 5 out of 5 by Awesome Pack Having used this pack as a National Park Ranger working in the backcountry, I really got to use this pack. I never realized how restrictive packs are until I used this pack. Note - the first time you use this pack it will throw you "off" because you are so mobile. The weight moves with you freely. The result is after you get you to that feeling - it will be the most comfortable pack you have worn. One negative is this is a heavy pack when empty... but it overcomes that negative by its amazing comfort. I have been recommending this pack to all of my friends. January 15, 2014
