Ultimate Direction Ultra Hydration Vest

The Comfort Cinch 3.0 system uses a simple, intuitive cord-and-lock mechanism on the back of the vest. You can easily reach back and pull the cords to tighten the fit instantly, allowing you to stabilize the pack as your hydration load decreases during a run.

The vest comes with two Body Bottle II 500mL flasks included. You will need to purchase a 2L reservoir separately if you prefer using a bladder system.

Yes, the vest features a dedicated waterproof main compartment and a water-resistant zippered phone pocket. These are designed to keep your electronics dry and secure even in wet weather conditions.

Yes, the vest includes integrated hook and bungee loops specifically designed for trekking pole attachment. This allows you to stow your poles securely when you aren't using them without needing to take off your pack.

The vest is constructed with breathable, chafe-resistant mesh panels designed to move naturally with your body. While individual sensitivity varies, these materials are specifically chosen to minimize friction during repetitive motion.

The 10.3-liter capacity is optimized for endurance racing and long training days. It comfortably fits the included flasks, a 2L reservoir, mandatory race gear, nutrition, and extra layers, all organized across nine different pockets for easy access.
