Best vest yet
Great durability and has all to storage I need for my long runs. Very easy to use and is comfortable and doesn't move around. Great value for what you can carry and the amount of water you can carry is perfect.

Great purchase
Love my running vest ! I love the fact I can put water in it, so I’m not holding it and it also keeps me cool. It holds my headphones and keys as well .

Comfortable and Affordable
Bought this for my first marathon and it worked like a charm! Lots of extra room and pockets for gels and salts. So much more affordable, but still made with quality.

Comfortable and reliable for long runs.
I've had this vest for a couple of months now. Still holding up. I did purchase the white. I do trail runs, so it got dirty quick. Not a issue for me, but some might not like that. It's light weight, I can fit my phone (S 25 Ultra), car key in the zipper pockets and collapsible water bottle and the vest still fits good. Highly recommend.

GREAT!
I am a long distance ultra runner. I have spent a ridiculous amount of time and money trying to find comfortable, durable and washable running packs w/ the right amount of easy to grab pockets. This is only $30. Every woman in my running group has bought one. I expected for this to be my "spare" pack, but it's quickly become my favorite. The bladder alone will cost $30 with other brands. It's not a big bladder for long summer trail runs, but it is perfect for winter running in the desert. I highly recommend this.

Quickly develops leaks--don't buy this
Bought this for marathon training and got about 7 long runs out of it before the plastic bladder developed a leak. The problem is that when it holds liquid, certain areas of the bladder kink (see picture)--over time and with movement (e.g., when RUNNING), these kink points undergo stress that shears and pierces the plastic. In the attached pictures you can see snakebite holes in the place where the plastic naturally bends, where the water can then leak out of. (The fourth picture shows a leak developing in the comparable spot on the opposite end of the bladder.) So, good news is that the liquid running down the back of my legs during my last long run wasn't diarrhea; bad news is that this is a poor-quality product and you are better off saving your pennies for something different!

Soft, lots of pockets, perfect for beginners!
This thing is awesome! It was super soft I was worried it was going to be rough. I’d say this is pretty good quality for what you pay. I haven’t tried the water bladder yet but it’s so light weight and has a lot of pockets. Perfect for beginners, I needed something to hold pepper spray and my phone and some electrolytes and water. Fits nicely just need to adjust the straps to your body. I’m a XL and a d cup size so I didn’t have issues wearing it.
