    I've tested three or four brands other than Camelback, and I can say that they are the best based on my experiences. Day hikes, overnighters, or weeklong camping… They have proven themselves repeatedly to be the best of all the ones out there. From leaking main covers to faulty bite valves, I've had all but the Camelbacks fail me at one time or another. Proof that "you get what you pay for."
