TRIWONDER Hydration Vest 2.5L Ultra Trail Running Backpack Hydration Pack Marathon Vest Lightweight Outdoor Hiking Cycling Daypack

This vest fits nicely and stays put. It has multiple front pockets and pockets along each side of the vest as well—and ladies, you know we need our pockets! The large back pocket can accommodate all sorts of stuff, perhaps even a water bladder. I also appreciate the fact that I can put my phone in one of the front pockets and not have it bounce at all while running. The mesh back makes it a great vest to wear for summer runs as well. Woild definitely recommend if you’re looking for a nice, durable, lightweight running vest with plenty of storage.

UPDATE: LOVED IT! Used it for training and my first marathon. It was just what I needed. When I first put it on the straps were wrapped and I didn’t realize it. 🤦🏻‍♀️ once I did and opened them up it fit perfectly. Even had room to spare. I was able to fit my water “bottle” my nuun, granola bars and apple sauce packets in the front pockets as well as a cooling towel and peanut butter crackers in the back. I recommend!!!Original post:I bought the medium/large. I measured myself and thought it would fit. It was snug. Would not be comfortable to run in.That being said, the material feels nice! Light, breathable. Going to return and order the L/XL and hope that fits!

Love the fit of this vest. Love that it has two water bottles. My only complaint is that the pockets that hold the water bottles aren't deep enough. There is a loop into which one can tuck the top of the bottle, but it's just a tad too small or too tight.This vest is DEFINTELY the best of the four or five others I've tried.

Used this for a 1/2 Marathon after trying my backpack style pack on a long run. Typically don't take any hydration that's why I said "tried".This was very comfortable and really easy to use. I could take a sip without removing the bladders from their pouches. I also was able to carry my phone and some small packets of nutrition along and really couldn't tell they were there.the only thing I don't like and doesn't really apply to this specific product but this style - having the bladders filled with cold water is not very comfortable when it's cool outside. I could imagine that a summer run it'd be amazing though.

Perfect size for most runs. I found I didn't carry a bladder most of time and didn't need the space. This pack is lighter and is not hot with the venting on the back. Pretty well made. The pack should fit tight so it does not bounce, if you are in between sizes I would order the smaller size. There is a lot of adjustment.

This item runs a little small. It was likely maid in Asia where on average people are smaller in all body dimensions than westerners so it being a tad tight should not surprise a western buyer.Pros:-Carries water bottles in a vest format.-Breathable back-Elastic loops to help water bottle straws from flopping around.Cons:-A bit tight, rides up and needs constant tugging down to set right.-Hard to adjust height of chest straps- the plastic "anchor" bits are very sharp . They come out easily but are hard to put back in. The edges are VERY sharp and can easily puncture your skin.-The rear pouch has no real closure and relies on fabric elasticity to hold items in. Anything heavier that a phone will cause significant sagging.-Item stretches which is good but if you do not have a flat chest, aka you have any sort of bust, I can not see how this item would fit unless you went a size up which may be too big(?)-Said elastic straps meant to hold water bottle straws in place do not stretch easily and you may break them if you attempt to loop them around the straw after putting bottles in chest pockets.-The emergency whistle? Yeah, it's utter crap and does not work. Even when I hook it up to an air compressor and let it rip beyond human capacity to blow- nothing. It's garbage. Throw it away and buy a real whistle.-Keys in the back pocket is a problem. When done running you have to take off the vest to get to your key. simple right? well, since if you have a phone back there, it all becomes one saggy mess and there is no fast way to get to your keys or phone. This is a bit of a pain and a problem with all these soft-shell pocket-in-the-rear models. A good vest will have a key pocket IN THE FRONT of your body where it makes sense. Also, if your phone is also your only time piece, then you have to take off the whole vest to check your phone just to see the time ... so wear a watch. A good running vest will also have a phone holding pouch in the front as well. For keys, I like to keep them in a zipped shorts pocket on some kind of retractable chord. Quick access and secure. Plus you will never loose your shorts while you may have to take off this vest some times.....So why did i get this item? Because the vest i wanted would have taken too long to get to my location via the mail. Lesson is, keep looking. You can do better. But in a pinch, this vest is okay.

Bought this ahead of the summer months of running. It's extremely comfortable to wear (for reference I'm 135lb and 5' 7" and got the m/l) because of how lightweight it is. The mesh backing is great and something I've been missing out on before. The pockets are good size, constructed well and I can fit my iphone and a couple of water bottles in there easily. I would recommend using the straw options with the collapsible bottles that came with the vest, just for more convenience. Overall, extremely happy with the purchase.

I got the vest just today as I was about to go in a run so I filled the bottles and threw on the vest. The first thing I noticed was that it was cinched all the way down and was only slightly fitted. I measured 111 cm which was right in the middle of the L/XL range. I should have gotten a M/L. I am 5’9” and 190lbs. The features seem decent. No telling on the quality yet. Definitely disappointed with sizing but it’s hard to tell until you run with it. I think I can tighten it up with some well-placed stitches. If there was an elastic pull string in the middle of the back, it would be perfect.
