Microban® Technology incorporated into our hydration systems does not reduce or eliminate the need to use good hygiene practices. The technology is not an alternative to good cleaning and care of your system, but is an aid in this process. The built in protection inhibits the growth of damaging microbes such as bacteria, mold, and mildew but does not protect the user from microbes already present in the water source.

SPECIAL NOTE: Works great with Accessory Side Pouches and Sleep Bag Compression Stuff Sack. Sold separately.
