Revolt Race Vest

(8 customer reviews)


The Revolt Race Vest is the most minimal, body-bare pack we offer. At a mere 7 ounces this pack allows for super cooling due to a very small footprint in the back, yet has a surprising capacity. The revolt includes our 550 UltraFlask Hybrid Bottle. The pack comes in new sizing, standard or long determined by both height of the runner and breadth of the shoulders. Capable of carrying 2 bottles in the back allow for farther distances between refueling and front pockets large enough to carry a large cell phone or any other essentials.



Recommended Use:
Minimalist and fast ultra racing in the heat with 1 hour between refueling stops.


  • Optimal center of gravity rear left or right side access holster for carrying a bottle and necessities.
  • Over-the-shoulder accessed expanding quick stash for gloves, sleeves, rain jacket or second bottle.
  • Max O2 Sternum™: A hook-type attachment system with enhanced recoil for better range of motion, and quick in and out.
  • Two front elasticized pockets hold gel flasks, multiple packets of gel or cell phone.
  • Adjustable shock cord closures double as attachment points for Z-poles or gloves.
  • Lower zippered pocket on one side, the other with a sweat-proof Magnon Electrolyte Pocket™ for dry pills.
  • Proprietary large-holed mesh, made of soft microfiber polyester for comfort and breathability.
  • Soft and supple perimeter binding made with polyester to wick away moisture, and stay comfortable against bare skin.

    This pack has cited my winter hydration woes. The low profile bottles come in and out nicely. If it’s colder than usual just slip it under another layer.

  2. Brian

    I love the minimal surface area of the Revolt! I can’t believe how much stuff it can carry with how small the pack is and its all easily accessible. This carries everything you need without the size or bulk of other packs. Its my new go to pack for both training and training.

  3. Kathy Kelly

    Yhis is my go to vest for almost every run. It is comfortable, great in hot weather and cold, and has just the right amount of storage. Wish it came in different colors

    Quite simply love it. Able to carry 1ltr of water/electrolyte/hydration without feeling like I’m carrying anything plus plenty of space for phone, energy bar or pills. Great quality, comfortable with zero rub

  5. Beth

    Love this vest. Fits me like a dream (I’m a medium-sized woman runner), carries everything I want and need (water, food, phone, keys), and I hardly know it’s there, even in the heat and sun. Big fan.

  6. Loren M Starr

    This is the only hydration pack that works for me. Light weight and easy to access fluids with no bounce. Love it.

    The Revolt was my first experience with UltrAspire. The simple design made this my go-to vest for all my summer training. I used it on everything from a 5k to half marathon distance. The chest pockets held my phone and any gels. While the flask was perfect to use for just a sip here and there with the shorter distances to getting me through the longer miles.

    I’m surprised I like this so much, but I do! It’s very comfortable for short/mid-distance runs. I thought it would bounce around; but it doesn’t. I thought the flask would be difficult to access and and return to it’s pouch; it’s not. I wasn’t sure my phone would fit in the front pocket; it does. I’m curious to see how it feels in warmer weather but I’ll have to wait a few months for that.
