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.

  • A low-profile vest built specifically for ultra runs
  • Stretch fabric contours and conforms to your body
  • Fabric also wicks away moisture and dries quickly
  • Reflective details and whistle offer enhanced safety
  • Bevy of pockets keep necessities close
  • Hydration soft flasks are included

Pockets for Snacks

  • Familiarity: I've used it several times

The SLab Sense Ultra 5 is a great little vest to stow everything you need for a half day's journey. The pockets are secure and fit loads of snacks and extras, without weighing you down. Salomon's soft flasks are fantastic, and easily slot into the front pockets even when full. The pack does not bounce around at all and remains comfortable even several hours in. I've so far taken this on runs up to 15 miles, and been really pleased.
I'm 5'6" 145, 34D and have the size small, fits well over a baselayer and shell.

It's Perfect

  • Familiarity: I've put it through the wringer

Stoked on this vest. When I first got it I was worried it might be too small...but it's actually quite perfect for half-day mountain running adventures. The pocket's are super stretchy and hold more than necessary. From running around volcanoes in Ecuador to casual runs in the Wasatch I definitely take the Sense Ultra 5 with me. This year's soft flasks are a great improvement and I don't have to worry about them disappearing to the bottom of the pocket because of the elastic bands.

Doesn't get much better!

  • Familiarity: I've put it through the wringer

My first running vest was the S-Lab ADV Skin 12-Set (go big or go home right?), which I wanted for the extra space, and room for a bladder in the back (think adventuring.)

Great pack, but over time I realized it's overkill for the majority of my running exploits. If you're not running in the high heat, 1L of water, an ultralight shell, some food, and maybe a headlamp just in case will take you far.

The Ultra 5L truly hits the sweet spot here, and it definitely feels smaller and lighter than its larger brethren.

The other boon with this years models is the improvements with respect to the soft flasks. The wide mouth top is a major upgrade if you want to use powders in your water. Additionally, they've added very small elastic keeper bands at the top of the water bottle pockets - which keep the nipples (is there a better word here?) of the soft flasks where you want them - at the top! On the previous years models, the soft flasks would sink down within the pockets as they get emptier - so this is a great improvement considering how small of a change it is.

Buy this vest!
