Review on Premium Azarxis Hydration Backpack Pack - Stay Hydrated during Marathon Trail Races: 5L / 5.5L / 8L Running Vest for Women and Men by Matthew Thorndike

I bought the vest without a hydration reservoir because I had my own 1.5 liter reservoir. The camel bladder fits perfectly in this vest. Not sure if it will fit a 2 liter bladder. may be.? The fit of the vest is great, no bouncing, lots of storage. I don't really notice I'm wearing this while running, it's very comfortable. I'm really glad I didn't spend a ton of money on a branded vest when it's great for my occasional long runs (like a few half marathons a year). Will it last forever? no Will it last a few years with occasional use? Yes. I would definitely buy this again.
