Osprey Dyna 6 is a lightweight and stable running vest designed for women who need comfort, capacity and easy access to fluids on long runs. The soft material and structured mesh panel with 360° stretch keep the vest close to the body without restricting movement, and reduce bounce even when the vest is fully loaded. Two soft Hydraulics™ 500 ml bottles are included, providing quick access to fluids and energy on the go. The vest also has room for extra clothing and equipment when the distance gets long.

The front is fitted with bottle pockets that keep the bottles secure, a zip pocket with a detachable emergency whistle, and several elasticated pockets for nutrition. Two adjustable elasticated cord closures make it easy to fine-tune the fit while running. At the back there are two low-profile zip compartments for organised storage or space for a hydration bladder. A handy stuff pocket lets you quickly stow a jacket or a layer on the move, and the front pole attachment makes it easy to switch between running and hiking on steep sections.

The Dyna 6 is compatible with the Duro Dyna Pro Quiver for additional pole storage, and also works with the Hydraulics 1.5 L hydration bladder. Reflective details increase visibility in the dark, and the magnetic bite valve holder keeps the drinking tube in place.
