The DURO 15 has ample hydration capacity and a lightweight build for trail running. The Vest-pack fit provides bounce-free stability. The mesh-covered, foam body-wrap harness system includes adjustable, removable chest straps, and a breathable mesh wrap backpanel. An included Hydraulics reservoir and soft-pack compatibility let you choose the hydration you prefer – or both if on a longer journey. The Hipbelt features zip pockets. A slotted adjustable sternum strap holds a safety whistle and the trekking-pole storage means you are fully equipped. Food, supplements, a flask, a phone, anything goes in the lower side panel stretch mesh pockets, two extra-large stretch mesh harness pockets, and two lower stretch mesh pockets. On the lower side panel are two stretch mesh zip pockets and a front panel zip slash pocket for quick access.
