I got a camelbak at the wal-mart that holds 2 liters and it has all the extra pockets for wallet,phone, keys, extra undies for those(oh shit) moments I fill it with ice and two bottles of water and it last me all day of riding. It was only 15 bucks on closeout so I bought 3 of them. That was two months ago I doubt they are carrying them now, seasonal shit you know. Anyways they work great and I love it. I say get one if you ever go hiking you can use it then too.
