Engineered for long distance races and fast-paced adventures, the Distance 4 Hydration Vest by BLACK DIAMOND for men has a running harness suspension made from stretchy, comfortable material that extends from the sides to the back panel with self-bound stretch mesh edges for ultimate comfort on the move.

The Distance 4 Hydration Vest by BLACK DIAMOND for men has an over the shoulder Z-Pole carry system that can be easily deployed on the go, while high stretch side panels extend from the harness itself for an improved fit while on the move.

The harness design also provides quick-access side pockets. Light materials provide temperature regulation and the colorways a better visibility. Dual flask pockets fit two HydraPak® SoftFlasks™ by BLACK DIAMOND - which are included with the vest - while a zippered chest pocket, lumbar and back zip security pockets and small stash pockets provide ample storage for essential supplies.
