Equipped with a Hydraulics LT 1.5 Reservoir and a number of aerobic-minded features, the streamlined Osprey Dyna 1.5 Women’s vest pack is specifically designed for female trail runners.
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. The AirMesh materials used on the backpanel enhance breathability and provide next-to-skin comfort. Other trail-friendly features include a zippered stash pocket on the harness, front harness stretch mesh pockets, and a zipper pull that doubles as a safety whistle.
A dedicated compartment houses the included 1.5 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.
The Osprey Dyna 1.5 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
- Perfect fit!
Likes: Shout out to Becky for helping me select this hydration vest. I was returning another vest that was not suitable and she told me about this Osprey vest. I wore it for a trail marathon and couldn't be happier. I had never worn a vest before and was blown away by how comfortable it was- I didn't even notice I had it on- I experienced zero "hot" spots and absolutely no chafing. The bladder took a call to customer service (thanks Shane!) to figure out but now a breeze.
Dislikes: Bladder was perfect for a well-supported trail race on a relatively mild day but might be lacking on a more humid day with few options to refill. Cleaning the bladder was a bit of a chore- had to improvise a system to get it fully dried. May need to invest in a cleaning kit.
- Awesome Pack!
Likes: I love all of the pockets on it. So many place to store the stuff that I need on my runs.
Dislikes: Maybe could be a little bit bigger of a bladder. It's a 1.5L Even a 2L would have been a little better. Nice thing is my 50 miler has aid stations every 4 miles so I don't see it being an issue.
