The Camelbak Cortez Hydration System is a paddle-friendly Camelbak that does away with that "back" necessity. That's because the Cortez secures directly to the deck of your kayak for a convenient source of water to drink from while you're paddling! Featuring Camelbak's Quick Link System, the Cortez clips onto the deck rigging of your kayak with a grip strip running horizontally on the back to help it stay in place. Containing a 3 liter Antidote reservoir that can be refilled by an external port, this Camelbak holds onto enough water for hours of paddling enjoyment. The tube of the Cortez is insulated to keep that the first sip of water you drink after awhile in the sun cool. To ensure that the only water you drink is the water found within the Cortez, this Camelbak also has a bite valve cover to keep river, lake or ocean water off the bite valve. Bungee straps on the back of the Camelbak Cortez lets you secure a hat when the wind picks up or holds onto a rain jacket when skies look cloudy. Paddle freely with thirst quenched with the Camelbak Cortez Hydration System.
