    Simplify your trail runs.

    Eliminate the bounce of a cumbersome pack and instead focus on setting a new trail FKT with the Osprey Packs Dyna 15 Hydration Pack. Proving that less is more, this true vest-pack provides bounce-free stability and comfort as you log mile after mile on your run.

    Its durable nylon design holds up against encounters with rough canyon walls and snagging branches, while the hipbelt wrap with zippered pockets not only stabilizes the ride, but also keeps the essentials right at your finger tips. An included Hydraulics 2.5L reservoir with attached hose and sternum magnet frees up your hands for easy drinking when you're in the middle of a lungbusting adventure, and the zippered main compartment and multiple pockets ensure you bring along your gloves, hat, headlamp, extra layers, GPS, and any energy gels you might need during your trail run.

    • Lightweight, vest-pack for hands-free hydration when you're running
    • 2.5-liter reservoir with hose keeps you well-hydrated
    • Waistbelt adds stability and eliminates bouncing
    • Multiple pockets offer room for all of your trail essentials

    10/10 Would Buy Again

    • Familiarity: I've used it several times

    For the longest time, I've been addicted to a variety of S-Lab running pack versions, initially because they changed the game in regards to fit, materials and features. I found that I was typically between sizes, not quite a unisex S or XS. Per a Backcountry Gearhead recommendation, I tried this bag and will never go back. It's a little beefy for a shorter runs, but excellent for long days on the trail. I run with my dog a lot, and find the pack much more accommodating of my needs and her snacks, water bowl and leash. My favorite part is the clip system. It stays put and is really easy to use, enables me to take my pack on and off quickly as needed when pup needs a treat. 10/10 would buy again!

    this bag is awesome!!

    • Familiarity: I've put it through the wringer

    I bought this bag to run/hike the rim to rim trail at the Grand Canyon and I absolutely love it for long hot runs! The ventilation and comfort are top notch, and it had minimal chaffing (hard to avoid some). I would highly recommend for longer run adventures as it allows you to carry more water than a lot of other vest style packs.

    15L Pack Perfect for long runs

    • Familiarity: I've used it several times

    I am 5'7", 150lb, and wear a 32C but the small fits with room in the straps for adjustment when wearing more layers. If anything, the bag is almost (but not quite) too big for my chest. I love the sternum magnet, it keeps the tube from inconveniently flopping around. There is room in the pockets for keys and phone, a change of clothes, my climbing shoes, and a meal with room to spare. With the many straps, the pack never bounces uncomfortably either. I've been running in late night downpours with this bag, and it dried out by the next morning with no odor or other problems. Overall a great trail running pack!

    Unanswered Question

    Does the Dyna 15 Hydration Pack come with the 1.5l hydration bladder and the two soft bottles in the front as in the picture?
