Review on Stay Hydrated on the Go with Source Hydration Bladder - 3L Water Bladder with High Flow Storm Valve and Hydration Technology Advantages by Carlos Abood

Cool piece! First, they work well. Does not leak and is very durable. I carried a 25lb load next to it and it has never leaked or broken in about a year. Next, and probably best, it doesn't taste like rubber at all to begin with. I also left the water there for about a month and it was delicious (disgusting I know). It's also easy to clean. Overall this is the best bubble in my opinion and you should just buy it because you won't regret it at all.
