    Well-prepared for what lies ahead.

    Stock the Ultimate Direction Mountain 4.0 Hydration Vest with all the water, snacks, and extra layers you need for a full day of running up steep trails and traversing high alpine ridge lines. The vest's Comfort Cinch technology consists of two bungee cords that can be quickly pulled or loosened to adjust the fit of the vest for a snug, secure, and bounce-free fit. Throw a pair of water bottles in the two front pockets for convenient access to water while you run, and be sure to throw some emergency essentials in the two side pockets so you don't find yourself miles from the nearest trailhead without the necessary emergency equipment to get yourself out when things don't go as you'd planned.

    • Familiarity: I've used it several times

    This new 4.0 Ultra Vest is the most comfortable running hydration vest that I've owned. They have implemented a new fit system called "Comfort Cinch" not quite sure how it works, but it feels amazing, it snugs up to your body perfectly and just disappears. The fabric has a great hand feel and has proved to be extremely durable thus far. The assortment of pockets have great accessibility and the placement is spot on, it's very convenient . You can tell a a lot of though went into this pack and that it was designed by people who actually run. Little things like a whistle implemented on the shoulder strap and slick way to carry your trekking poles are just a few of the neat features.

    Am I even wearing a vest?

    Are the chest straps can be slided up and down?
