Ultraspire momentum Vest v1

General Overview

The Ultraspire Momentum Vest is a light weight, breathable, no-fuss running vest for the runner that prefers bottle hydration and wants space for all the essentials.

  • Light: there are lighter vests out there, but few that offer as many storage options 
  • Durable: quality materials that are resistant to abrasion and tears
  • Breathable: excellent job not absorbing sweat or taking on water weight 
  • Comfortable: the edges of the vest are soft and non-abrasive to skin/clothing
  • Versatile: suitable for 10 miles around the block or races of 100+ miles (with aid stations)

Front Chest Pockets

  • Intended for bottles (vest not setup for bladder system), but could be used for additional storage for essentials
  • Shape and size of pockets will fit many different brands/styles of bottles (soft, hybrid or hard bottles) 
    • UltrAspire Ultraflask 550ml (not included with the vest) 
      • Have a unique shape which is designed to match the curvature of the chest or sides/hips to eliminate as much movement as possible, which cuts down on rubbing and irritation
      • Bottles are a semi-soft material: firm enough to be easily filled and accessed/removed while still remaining comfortable

Side Stash Pockets

  • Open pockets (not zippered) offer easily accessible storage space with soft edges; this is a marked improvement over other vest models where (if the space is utilized) the pockets are often difficult to access and/or the zippers cause undesired rubbing. 
  • Beyond nutrition, also great for items you will need soon or just got done using, such as headlamps or toiletries

Overall Fit

  • Easily fitted: simply pull the two bungees across chest, hook on the opposite side, and tighten bungees until snug. With just the two adjustment points you get a snug fit without any additional straps to contend with.
  • The bungees are not restrictive and do not affect breathing.
  • Sizing: SM (31”-36”) MD (34”-39”) LG (37”-42”)
    • Sizing is true to size
    • Given the bungee closure system, even those measuring the at the upper end of a size range can still expect to have room for layers


  • Pill Pocket seems like too specialized of a purpose for a pocket; optimally this would be a bigger and more generally purposed compartment
  • Does not come with any bottles; although this keeps the overall price low and allows for flexibility of bottle choices, it would be nice if the Ultraflask 550 Bottles were included

Not the Running Vest for You

  • If you need more gear space for multi-day races or ones with a mandatory gear list, then jump to bigger volume pack models and keep this for everything else.
  • If you prefer a bladder hydration system, there are plenty of other vest models with that capability
