At the heart of the Baltoro and Deva Series lies the latest evolution of our groundbreaking, award-winning Response suspension system.

The proprietary A3 and women’s-specific A3W chassis are the reason these packs remain comfortable and balanced, mile after mile, through shifting terrain, conditions, and intensity levels.

Discover the tech yourself

    1. A3 technology allows both the shoulder harness and hipbelt load panels to pivot independently, adapting instantly to the shape of your body and your movements.
    2. A lightweight Wishbone internal perimeter frame, an all-new ventilated backpanel, and contoured LifeSpan foam harness padding make Response A3 and A3W not just the best fitting, but the most dynamic and versatile suspension designs we’ve ever developed.
    3. Meanwhile, the Lumbar Tune insert allows the user to adjust the amount and placement of lower back curvature, providing incredible contour matching and load management.
