Equipped with a Hydraulics LT 2.5 Reservoir, gear-storing capacity, and a number of easy-access organizational features, the Osprey Dyna 15 Women’s hydration vest pack is designed for long ultra races or unsupported backcountry running adventures.
Featuring comfortable, breathable mesh, the pack’s harness is designed to mirror the contours of your body, offering a 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. A padded hipbelt with a user-friendly ErgoPull closure further stabilizes weight and allows you to carry all the gear you need for a long day on the trail. The AirMesh materials used on the backpanel and hipbelt enhance breathability and provide next-to-skin comfort. Compression straps help to keep your entire load balanced and stabilized.
The main compartment of the Dyna 15 Women’s pack has dual zippered access points. There is a front panel compression pocket and a smaller zippered front stash pocket. A dedicated compartment houses the included 2.5 liter hydration system and a zippered entry allows hassle-free access. A QuickConnect feature on the detachable drinking tube allows for faster refills and a magnetic bite valve provides a high flow rate and connects efficiently to a magnet on the front of the harness when not in use. The reservoir’s wide mouth is easily accessed by a large, quick-seal cap that further adds speed and efficiency to refills. An anti-microbial treatment fights bacteria build-up inside the BPA and PVC-free reservoir and keeps water tasting fresh and clean.
Other trail-friendly features include a zippered stash pocket on the harness with a zipper pull that doubles as a safety whistle, deep and over-sized stretch mesh harness pockets that are ideal for flasks or phones, two additional, smaller stretch mesh harness pockets, and zippered hipbelt pockets.
The Osprey Dyna 15 Women’s 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 Xsmall/Small size best fits chests measuring 31”-37” and the Small/Medium best fits from 35”-41”.

Real Customer Reviews
- Excellent pack for longer runs
Likes: So far I've taken my new (now sweat stained) Osprey Dyna pack on several 3 to five hour trail runs in the High Schell Mountains of Nevada and on some trail runs in southern Utah. I opted for the 15 liter pack with 2.5 L hydration reservoir because I exist in hot, dry climates for work, and thus recreation. I don't tolerate heat well and having the extra water available makes long runs possible. Pack size is perfect for a map, SPOT, snacks and micro water filter I carry for emergencies. And I anticipate the extra pack space will come in handy for layers when the weather turns brutally cold this winter. I initially bought the pack because my other, much cheaper tiny day pack that I was using chafed my shoulders. The Dyna is everything I hoped for in that department: no chafed shoulders.
Dislikes: There isn't much I dislike about the pack. My only possible comment in that regard is fairly negligible: when the hydration reservoir is filled all the way to the 2.5 L mark, it pushes out more into my back and sits slightly less comfortably even with some slight strap adjustments. That issue is fairly quickly remedied as I drink water.
