Equipped with a run-specific 2.5 liter reservoir, ample gear-storing capacity, and easy-access organizational features, the Osprey Dyna 15 hydration vest pack is ready to help you tackle challenging ultra races or your own unsupported backcountry running adventures.
Featuring comfortable, breathable mesh, the pack's harness is designed to mirror the contours of your body, offering a bounce-free fit that feels more natural than that of many traditional backpacks. Dual chest strap buckles stabilize fit and offer a broad range of adjustability. A unique tabbed design allows you to disconnect the straps from either side of the harness or remove them entirely. To help support the load, the suspension system has lightweight foam built in to the backpanel and a low-profile hipbelt with contoured side wings. The hipbelt has a user-friendly ErgoPull closure for quick adjustment. The spacermesh materials used on the backpanel and hipbelt enhance breathability and provide next-to-skin comfort.
The pack's main compartment has a large zippered opening for easy access. A stretch mesh pocket on the front panel provides a place to quickly stash gear you're likely to need on the trail. At the back of the pack, a dedicated compartment houses the included Hydraulics 2.5L LT hydration system. The zippered entry extends over the hose path for quick and easy loading. The run-specific reservoir is lightweight and more compact for integrated use with the pack. The hose is insulated to keep your water protected from both the warmth from the sun and body heat as well as moderate cold when the temperatures drop.
On the harness, there are plenty of pockets for on-the-go access. Two tall stretch mesh pockets can accommodate soft flasks (sold separately) or food. Four additional stretch mesh pockets on the lower part of the harness help to organize food, gels, or supplements. A vertical zippered pocket behind one of the tall flask/food pockets holds a phone or valuables. The hipbelt has two extra large zippered pockets and smaller stretch mesh pockets. A tuckaway safety whistle is also included.
The Osprey Dyna 15 hydration vest pack is available in your choice of color and size options. Sizing is based on the circumference of your chest, measured at the widest part of the chest slightly below your armpits. The Small/Medium size best fits chests measuring 26"-35" and the Medium/Large best fits from 35"-41".
