The Condor Torrent Reservoir is equipped with the quick-disconnect feature which allows for you to conveniently refill the reservoir without the hassle of removing and reinserting the drinking tube. In addition, the integrated built-in auto shut off valve stops water flow when disconnected. The large bite valve offers fast, unrestricted water flow for when it's needed most, and a quick shut-off bit valve when you don't. Its low-profile design is compatible with all Condor hydration packs.
