Made of food grade materials, this BPA-Free and Phthalate-Free hydration pack has no taste other than what youÕre drinking. Fill it with water, sports drinks, or even a 2 L box of wine (you know you were thinking that too!). The Cenote Hydration System Water Storage Bladder is constructed to be totally leak free, from water bladder, to cap connector, to sturdy and durable hose, to drinking valve. Fill it, cap it and go, and know it will hold up no matter how you use it. Allowing for maximum flow, with no spills, leaks or extra work, people love the Cenote Hydration System Water Storage BladderÕs High-Flow Bite Valve. Just turn the bite valve to be perpendicular to the hose, bite on the clear silicone and suck. Boasts a 360 degree bite zone! Wash and reuse the Cenote Hydration System Water Storage Bladder as many times as you like. And when you decide itÕs time to replace the bag, cut the hard #4 plastic fitment from the #2 plastic bag and recycle them! Holds 2 Liters, weighs 1.6 ounces, and measures 19.25Ó in length by 8.5Ó in width.
