Not a Camelback, but much less expensive. It's good for short 3-6 hour hikes, maybe even longer hikes depending on the amount of stuff you need to take with you. For a 12 hour Yosemite, Half-dome day hike, I found it a little small. Besides, you really need more water then 2L for Half-Dome. However, for shorter hikes, I do believe that it was great hydration pack for the price. Just make sure you tighten the tube to the water bag. (They use a screw on tube connector... Camel back is just push on... I didn't realize this till after my first short hike with this bag.) Oh, the water bladder did make it up with my to Half-dome, along with another 2L bladder and a larger bag.
