Osprey Dyna Pro 7 Women's Running Hydration Vest

The Osprey Dyna Pro 7 is an ultralight women's running hydration vest built for racing and developed with elite athletes. Its women's-specific shaping on the Dyna yoke and harness contours to shorter, narrower, curved body types, while the restricted-stretch backpanel stabilizes the load without restricting natural movement.

Two Hydraulics 500 mL Soft Flasks with removable WingStay stabilizers are included, and the removable Duro Dyna Pro Quiver lets you stow trekking poles on the go, anchored diagonally or vertically. Storage includes a pass-through lumbar pocket, an upper back stash pocket, an upper zippered pocket with an internal cord, a vertical-zip front pocket and four stretch drop-in pockets, with front and rear reflective details for visibility.
