Review on Stay Hydrated Anywhere with the CamelBak Classic Hydration Pack, 85oz by Angel Scully

Perfect size and holds enough water for my cross country tours. Fill it completely with ice and it will keep it cold all the time. Even after my trip, there was still a fair amount of ice in my bladder. I've noticed that some people say the bladder is leaking and the lid doesn't fit. This has only happened to me twice. Filled it up and turned it over to see if the cap was leaking. And when that's the case, I just unscrew the cap, put it back on and make sure it's tightly closed, no leaks.
