This is the second tank that I buy and compared to my first purchase "white product" I am impressed by the strength and Camelback design. It is worth its price. Great solid feel. Largemouth but very tight and easy to open / close (quarter turn). The small top to hook the tank allows me to suspend my backpack, giving greater comfort that packed into the background. Detachable hose with a simple clip (useful for not just detach from your backpack when you fill the tank). Solid tip with tap practical closure. Hint: fill it fully to avoid water noises in the backpack. If you do not let air go drinking, it will shrink slowly and do not make a noise! In short, that's good.
