UltrAspire Momentum Race Vest

Fit: Sizing is usually true to size. UltrAspire's website offers a fitting guide for those who are unfamiliar with their products. 

Comfort: No issues with chafing from the pack even when loaded to full capacity. Have used this pack for up to 11 continuous hours with no chafing or discomfort. Would always recommend a Body Glide type product if doing multi-hour or full day outings where you would be wearing a vest. 

Capacity: Fluid capacity without a bladder is what makes this a very good vest for the trails. I typically like to have a water filter on me in the mountains and there is room for this, a shell, and food. For improving this vest I would recommend increasing the back zipper pocket slightly or making it out of a material that would expand when stretched. 

Accessibility: For me having the bottles on the lower back hips was a perfect spot to carry reserves. It does take some getting used to reaching around and accessing these bottles however and it could be an issue with someone with limited range of motion in the shoulders. 

Ride: No bounce! This is one of the single most important elements I look for in a trail running vest. If you have the right size vest there should be no noticeable bounce even when the vest is fully loaded. 

Compression: The advantage of this vest is you could wear it for an easy short outing and only have one bottle, a phone, and a shell OR you could load the whole thing up and have enough water and supplies that could get you through 3-4 hours depending on your fluid intake schedule. 

Ease of use: Only piece that I would like to see improved is the pole storage. While it works it is something that could be better. If someone had limited shoulder mobility they might be required to take the vest off to move the bottles from the back to upfront versus reaching back and doing so. 

Features: Really nice having the four-bottle capacity. There is still a bunch of storage options along the sides and the front of the vest. Easy to organize calories, gear, trash, etc. 

Durability: No wear noticed yet as of six months of use. Every other week I empty the pack and hand wash and hang to dry. This has kept the pack from developing odor and looking basically like I just bought it. 

Use/Conditions: Have been using for the summer of 2019 almost every weekend. Have used it for several all day outings and for an 11-hour race and it has performed well in a broad range of uses.
