New, ergonomically optimized DNA Race Backpack has a reduced volume of 16 liters. It sits better next to your body as its predecessor, which is particularly due to the stretch front adjustment system. The Airmesh fabric on your back and breathable shoulder straps ensure you have optimum breathability. The DNA 16 offers a number of features, including a removable bottle holder, an ice axe attachment, a waterproof pocket and pockets for soft flasks. In addition, it is compatible with most hydration systems and has removable ski carrying attachments.
