The Ultimate Kit has you prepared for any outdoor challenge. It combines Source's classic Widepac water bladder with three essential hydration accessories: the weave covered drinking tube blocks UV radiation and prevents bacteria growth inside the tube; the Magnetic Clip keeps the drinking valve in place while you’re on the move; and the Universal Tube Adaptor allows you to refill your drinking bladder directly through the drinking tube from all standard water tabs or bottles, without removing it from your hydration pack.

Includes the leak-proof, high-flow Helix Bite Valve with a dirt shield. The Widepac bladder fits most regular hydration backpacks.
