Capacity is never an issue with the Deva 80, making it the ideal choice for unsupported backcountry trip or a weekend where no creature comfort can be spared. All year round, from sea level to the high alpine, ventilated Response A3 suspension handles heavy loads with grace and poise no matter the terrain or conditions.
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
