Ultra-light materials and a streamlined design make this vest ideal for long-distance training
and elite-level racing. Available in multiple sizes and equipped with two Quick StowTM 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. The Ultra Pro boasts reflective accents throughout, so you’ll always be visible on early morning or late-night expeditions. The two 17-ounce Quick Stow flasks are lightweight, collapsible and feature a one-piece silicone bite valve for rapid hydration on race day.
