Keep you handsfree hydration system clean and mildew free with the help of the Cleaning Brush Set from CamelBak. CamelBak's line of hydration packs have proven to be lifesaving advantages on intense missions, hikes and other physically demanding endeavors. The problem is the same compact nature that makes them so convenient, also makes them challenging to clean. Moisture can get trapped, leading the buildup of mildew and other bacteria. This flexible brush set reaches into every corner of the reservoir and every inch of the delivery tube. A radial tip on the brush prevents punctures and memory bristles ensure that no inch goes unscrubbed.
