Osprey Dyna Pro 10 is an ultralight, competition-focused running vest developed in collaboration with experienced elite runners. It is fine-tuned for ultrarunning and long distances, with a stable fit specifically designed for women. The vest comes with two soft Hydraulics™ bottles of 500 ml and ensures efficient hydration without creating movement or bounce. The combination of smart pocket placement, quick access to gear and multiple pole attachment options makes it an optimal choice when every second counts.

The vest features a spacious zippered main compartment and an integrated tunnel pocket in the lower back that accommodates extra layers and nutrition. Pockets in the upper back and a top-mounted zip pocket keep larger items securely in place. Four elastic pockets at the front and sides provide quick access to nutrition, and the bottle pockets are designed for maximum stability. Also included is the removable Duro Dyna Pro Quiver, which offers multiple ways to attach and carry poles while on the move.

The front features a zip pocket for small items, an attachment loop for a GPS device as required in many races, and a removable emergency whistle. The vest is also compatible with the Hydraulics LS 1.5 L hydration bladder. Reflective details front and back increase visibility in low-light conditions, and the adjustable toggle closures provide a personalised and secure fit.
