Updated quick disconnect is water tight on both sides when disconnected. 
The HAK is the perfect add-on to any Swig Rig package. It included as Quick Disconnect and Hose Clip. Both come in very handy when customizing your Swig Rig to your kit. The Hose Clip keeps the Bite Valve close at hand and ready to use while the QD allows easy removal of your bottle from your pack without removing your hose.
