Ultra-light materials and a streamlined design make this vest ideal for long-distance training and elite-level racing. Equipped with two Quick Stow flasks, the Ultra Pro vest puts comfort above all else.

The vest is made with 3D vent mesh—an ultralight material that guarantees maximum airflow on sweaty runs. It also offers plenty of front storage pockets for easy access to fuel, water or salt tabs, along with a secure zippered pocket that fits most smartphones.

The back features several stretch pockets that can store extra layers on cold days, but also accommodates an additional reservoir for longer self-supported runs. We’ve also added reflective accents throughout, so you’ll always be visible on early morning or late-night expeditions.

• 3D Mesh: Lightweight, cushioned mesh maximizes airflow and reduces chafing for cooler, more comfortable runs.
• Quick Stow Flask: This lightweight flask collapses to fit easily in a running vest, belt, or even your hand. The jet valve self-seals to eliminate drips and leaks.

  The leak-proof On/Off lever helps prevent drips and leaks while your flask is stored away and also lets you control the amount of water you want.

• Dual Adjustable Sternum Straps: Dual adjustable sternum straps increase stability and offer a range of adjustments for customization. Straps can be tightened or loosened as well as being moved vertically to get the most comfortable fit.

• Lightweight Cargo Capacity: Stretch overflow pocket offers easy access to toss in a rain shell or stash extra gear.

  Harness storage for all your run essentials offers organization for fuel and gear, including a secure phone pocket and specially designed Quick Stow flask pockets.
