Bottom Line
Nearly all vests on the market are geared toward flask and/or reservoir users, but the UltrAspire Momentum 3.0 is made for those who prefer bottles. There are bottle-friendly pockets at both the front and rear, the latter of which are mounted on a guided rail system for easier access.
Though the Momentum 3.0 weighs a bit more than other vests we tested, this lends itself to a more durable pack that can really go the distance. Made from sweat-proof webbing, it didn’t grow soggy or retain moisture on wet runs in the Pacific Northwest.
With UltrAspire’s signature ErgoFit design, we felt like the vest hugged our bodies perfectly and didn’t move around during movement. However, it’s worth noting that some testers found the position of the rear bottles to be uncomfortably low. You can read more about our top picks in our guide to the best running vests.
How We Tested
We tested this vest over a two-month period in variable weather, from 50-degree spring days to 20-degree late-winter runs where layers were key. We tested it on our daily five-miler while visiting the Midwest. We also took it on sloppy, wet training runs in the foothills in Washington State, where our efforts ranged from 5 to 15 miles.

Comfort & Fit
UltrAspire is known for their ErgoFit design and attention to detail, and the Momentum 3.0 delivers. We found this to be one of the more comfortable packs we tested with minimal bounce and a secure, close-to-body fit. The S-curve shoulder straps didn’t restrict our arms and kept us from experiencing neck and underarm chafing during long efforts. However, some testers found the fabric to be a bit scratchy on bare skin.
Another thing to note is that the pack has a low center of gravity for maximizing stability. We normally appreciate this feature, but in the case of the Momentum 3.0, we found the positioning of the water bottles in the lumbar region too low and slightly uncomfortable on longer outings. Some testers didn’t like the pressure over their kidneys.
This vest is significantly heavier than many others we tested, which is great for durability. However, we did notice the added ounces on multi-hour runs and outings when the pack was fully loaded.
Functionality
The number and arrangement of front pockets helped us stay organized with a convenient spot to stash jackets, gels, and other essentials.The rear stash pocket was invaluable on longer runs in Michigan’s variable late winter/early spring climate, allowing us to quickly stash and retrieve layers as conditions changed. We also appreciated the inclusion of a zippered security pocket for keeping our valuables safe while running.
The inclusion of bottle pockets is rare these days, with most vests only able to accommodate flasks and/or a reservoir. The Momentum 3.0 can fit two bottles at the back, along with two 500-milliliter bottles at the front. UltrAspire includes two of their UltraFlask 550 Hybrid bottles with purchase.
Rounding out the feature set, the Momentum 3.0 is also quiver-compatible for those who prefer that system for their trekking poles. The quiver can be attached at either side.
Performance
Although the Momentum 3.0’s overall fit and functionality are top-notch, we did feel like performance was lacking in a few areas. Some testers found it hard to access the lumbar bottle pockets due to their placement. On the plus side, they are fully out of the way of swinging arms, which can be an issue with rear bottle storage.
The upgraded MaxO2 closure system was finicky, as well. We found the buckles on the straps to be annoying to deal with and hard to use, especially on the go. However, the system adjusts both horizontally and vertically, making it easy to dial in a good fit. Once it was set, the pack rode great with no bounce and no further adjustments needed.
Durability
The Momentum 3.0 was one of the most durable vests we tested. The silicone and PU-coated nylon fabric is resistant to abrasion and snags, and it does a nice job repelling moisture, too. Not a stitch is out of place after months of use, including long spring runs that required clambering over – and at times getting caught on – deadfall.
We also noted that there was bar tacking on stress points and zig-zag stitching on the elastics. UltrAspire’s attention to detail gives us confidence that the Momentum 3.0 will last a very long time.
Breathability
We found the porous UltrAcool mesh to be highly breathable. On warmer runs on sunny days in the Midwest, the vest wicked sweat rapidly, so we never felt swampy. Combined with the microfiber bindings, we had zero issues with chafing. On rainy days, the fabric didn’t get saturated or bogged down, which was great considering the vest is on the heavier side to begin with.
Our only complaint about breathability was that the close fit covers a lot of the torso, which might make it feel hot for runners pushing hard in warmer conditions. Additionally, some testers noted that because the bottles are on the lower back, that area didn’t wick moisture away from the body quickly, which led to some sogginess.
Should You Buy The UltrAspire Momentum 3.0?
Bottle fans rejoice: The UltrAspire Momentum 3.0 is made for you. There are two bottle pockets at the back and two at the front, all of which can accommodate 550-milliliter bottles (two are included with purchase). The front pockets also have bungee straps for securing flasks, if that’s your preference.
UltrAspire’s signature ErgoFit design is comfortable and secure, and the pack is made from highly durable fabrics that stand up well to rough use. That said, this does impact breathability, and some runners may find the vest too warm for hot conditions. It’s also only offered in a single 6-liter size, which may be limiting on all-day objectives that require a lot of water, snacks, and layers.
What Other Hydration Vests Should You Consider?
If the UltrAspire Momentum 3.0 Race Vest catches your eye but you’re not sold just yet, check out these other great options from our best running vests gear guide:
UltrAspire Alpha 6.0 Race Vest Review: Another solid offering from UltrAspire, the Alpha 6.0 has more traditional hydration compatibility (two flasks and/or a reservoir) and offers a step up in breathability. It’s also lighter than the Momentum 3.0 but costs a little more.
Ultimate Direction Men’s Ultra Vest / Women’s Ultra Vesta 6.0 Review: For a boost in capacity, we really like the Ultra Vest/Vesta. The design is a jack of all trades that combines great comfort, organization, and durability in a premium-feeling package.
Salomon ADV Skin 5 Review: If you don’t need the Momentum’s bottle compatibility, the ADV Skin 5 is a nice alternative. It has a secure fit, generous organization, and all the features we look for in a middle-of-the-road option.
