Sometimes staying hydrated is harder than you think. However, the Salomon S-Lab Sense Ultra 5 Set Hydration Vest is designed to make things a little easier—not to mention, a little more well-balanced. To achieve such a feat, the Ultra 5 features Salomon's SensiFit design, which provides a contoured fit that's ideal for aerobic activities.

Additionally, the Ultra 5 Set Hydration Vest puts comfort at the forefront of its design, starting with its breathable, soft, and stretchy fabric construction. This use of fabric in turn promotes full mobility and a barely-there fit and feel, while the fabric itself is quick-drying and moisture-wicking. The Ultra 5 is completely bladder-less, though it does come with two front soft flasks that are specifically built for hydration—as a result, the Ultra 5 is best suited for races or runs where aid stations are a-plenty. An included whistle and reflective detail enhance your overall safety levels, but that's not to say you should head out the door without proper protection. Not to mention, a bevy of extra pockets keep necessities close at hand and secure, but without bogging you down.
