The director knows everything and remembers it all. Just like the Tube Director from CamelBak. This well-insulated drinking tube provides you with a reliable, long-term supply of chilled drinks from the CamelBak Crux Reservoir hydration bladder, even when it's warm outside. And the special feature of this director is its memory function. Once you bend it the way you need your drinking tube, it stays in that position. Clever little guy.
