Fluid™ Race VestPack is rated 3.0 out of 5 by 2.
Rated 2 out of 5 by from Too Large Everywhere (Pockets too) So in my search for a running vest, I went to MH to try on their running vests. They did not have the VestPack on the floor so I tried on the Race Vest (3L), not Race VestPack (6L). I have to say I fell in love with the way the 3L Vest fit my body, but I didn't like the amount of space it had. The back compartment only has enough for your hydration pack. So I thought that by purchasing the 6L online, I would be essentially getting the same fit but larger volume to store a shell, some snacks, and aid kit, etc.... To my dismay, these two sister packs do NOT fit the same. The 3L fits snug, while the 6L required 30% more torso mass to fill up space. I am 5'1", 113lbs roughly. I have to say that I'm very disappointed that these two packs do not fit the same. I even went as far as filling up the pack completely to see if that had any difference, but no... it's still very very loose. I will have to find a different brand if I want equal amount of space, or let that idea go and settle for the 3L .. Lastly, I had read on another review that the front pockets were too large and that items were getting lost in the depth of it. This is also true. I could fit my normal 24oz water bottle in the whole way in!!! I think it would be nicer to find a happy medium between the front pockets in the 6L which are large, and the small pockets in the 3L which are small. So sad MH let me down this week ;-( (I would recommend this product only if it fits you perfectly as it could cause chaffing.)

Rated 4 out of 5 by from Pretty Darn Good As of this review I've used the MH Fluid VP 4 or 5 times for a total of approx 30 miles, all on trails. Pros: -Very Lightweight -Very Comfortable -Ample Pocket/Pack Space, Front and Back -Plenty of different pockets, without feeling overwhelmed by pocket options -Great with soft water bottles in the front pockets -Looks pretty nice, which I can pretend not to care about, but it does come into play. Cons: -I'm 6'3, 170lb and the M/L is a bit too large. Granted my chest cavity is on the small size -Slight weight imbalance with water bottle in the front pockets and nothing in the back -Front large pockets are maybe a bit deeper than I'd like, kind of hard to fish things out while running. Summary: Overall I'm very happy with how the vest-pack has performed so far. I run a lot in the 6-8 mile range, which doesn't really warrant a pack of this sort, but I am training for a 50K, and the training schedule will have me running more 15-22 mile trail runs, unsupported. This pack should be perfect for that, and for the 25K races I run on every couple of months. I've also been very happy using this for fast-hiking, much nicer than a standard daypack, and plenty of space for a small camera, food and hydration. Suggestion: Side adjustment. I am actually going to have to rig something for this as I have a little too much bounce when I have water in the front, and an empty back. Until then, I think I'll have to put something in the back just to help balance the weight. Cinching in the sides an extra inch or so would help the pack stay put properly and minimize the bounce. I found this just by grabbing them while running. Also, I think the depth of the front water pockets could be reconsidered. They feel maybe 1/2" too deep? Maybe moving the pockets up a smidge and placing a horizontal gel/key pocket below? All in all I'm very happy with the pack, and even more impressed with the price point when compared to other products of similar quality/size.
