    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
    • Item #SAL00VR

    The best of the best

    • Familiarity: I've used it several times

    There are countless hydration vests on the market but there is a reason Salomon is the king of all things trail. This is vest is incredibly light, has tons of pockets for snacks (including two zippered ones for phone/keys), plus a larger pouch on the back for an extra layer. The two soft flasks offer plenty of volume for liquids on race days as you hop between aid stations however I would agree with the previous reviewer that 15-20 miles is probably the most I would use this for an unsupported run. The weight, comfort, functionality, and durability make this vest well worth the slightly higher price point than others on the market.

    My favorite vest!

    • Familiarity: I've put it through the wringer

    When I started working for Salomon, this was the first vest I got, and I love it! It's incredibly lightweight, holds everything I like to bring with me, without weighing me down. Phone, GoPro, sunglasses, nutrition, extra layer, it holds it all!
    I'm 5'2, 120, and wear an XS. You want to make sure it's snug!

    Race day

      The sense ultra 5 is verestile and well rounded for a half day adventure on the trails. Plenty of room for snacks and an extra layer, and everything fits close to your body so your gear isn’t sloshing around. I recently wore this for a 40 mile race and found this to be perfect and breathable for a summer day while offering enough water storage to get from aid station to aid station. For an unsupported run I don’t think I would use this for more than 20 miles, but as a sleek race vest the two 500ml flask are great. Speaking of the flasks, they were awkward at first and actually bruised my ribs, don’t do a 20 mile run in new gear, but after a few runs I actually prefer this to a bladder since I don’t have to take the vest off to refill. As far as fit goes, medium was spot on for me and I am 6’1’’ 175 lbs with a 30 waist. Overall, this is an incredible vest that is comfortable to wear and offers just the right amount of space for anything from a 10k to a 50 mile race.

      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!

      Sean, your description sounds like why I'm looking at this vest. I have the 12L Adv Skin as well. How is the kangaroo pocket in the back for holding a rain jacket? I love the kangaroo pocket the Adv Skin Set 12L has. This pack looks like the jacket is higher against the back as opposed Adv Skin 12. Seems that would be hotter.
