Cleaning a wide mouth water bottle is one thing, but properly cleaning a hydration system is a different matter. Fortunately, the folks at Camelbak have come up with a Cleaning Kit to make this task easy. The kit contains two brushes, one designed to scrub the delivery tube, and one designed to clean the reservoir. A cleaning tablet aids the process without leaving unwanted taste or odor, and a collapsible reservoir dryer improves drying efficiency.
