The Widepac Ultimate 2 hydration system from Source is the proven and always available outdoor beverage supplier. The large hydration bladder is reliably robust and compact. It features a wide opening and a large extra screw cap for easy filling, cleaning, and emptying. Its sophisticated Helix Bite Valve has three different positions: open for drinking, closed for transport, and middle for cleaning. The leak-proof SQC push button allows for easy and secure attachment and detachment of the drinking tube. In addition to the Widepac Premium 2 model, the Ultimate variant has an inner wall that provides a flat profile for better portability, as well as a robust cooling and UV protection sleeve for the tube. The Widepac Ultimate 2 hydration system is perfectly rounded off with its textured surface design and ergonomic transport handle.
