Review on INOXTO Hydration Backpack，Insulated Lightweight Backpack by Bryan Gallardo

This backpack was bought mainly for MTB. It's the right size and is very light. With straps on the sides, it stretches and contracts easily. The zippers and stitching appear to be good. I've also used it for day hikes and kept flying under the seat. The detachable bladder, which I've used for longer rides, works well enough, the only sticking point is that the water flow in the bite valve is more restricted than I'd like. I also tried the helmet mesh but I think it's pretty much useless. All in all what I was looking for at a great price.
