You’ll be surprised by how capable the smallest Deva pack can be in so many situations. For short and long weekends, it’s more than
perfect, offering superior balance and carrying comfort for heavier extras like a climbing rack or a gourmet camp meal complete with a bottle of bubbly. The Deva is already a feature-rich pack, but Response A3 makes the difference—because when you combine shorter trips with Gregory’s best suspension technology, you forget about what you’re carrying and escape into the journey.
Response A3 Tragesystem
The hip and shoulder straps with automatic angle adjustment (A3) adjust individually to your physique every time you shoulder the backpack for a perfect fit. This patented system allows shoulder and hip straps to rotate independently to provide a dynamic and stable forward motion that follows your body's movements in any terrain. With the Response A3 carrying system, your body's centre of gravity remains balanced on the move, saving you the energy you would otherwise need to constantly stabilise. This little bit of energy saved with every step adds up, improves your performance and keeps you happy as you go mile after mile.
Measuring the back length
Measure with a tape measure along the spine from the 7th cervical vertebrae (the spinous process is easy to feel from the outside at the lower end of the neck furrow) to the iliac crest (at the level of the upper bony hip structure). Measure two or three times to get an accurate result. If you are between two frame sizes, the smaller size is right for you.
XS = 36 cm - 41 cm
S = 41 cm - 46 cm
M = 46 cm - 51 cm
L = 51 cm - 56 cm
