While this system has been mentioned several times on BPL, some folks at the SoCal GGG hadn't heard of it before, so here's a description, a couple photos and a link.

The SmarTube turns a water bottle into a "sip anytime" hydration system. It comes with the essential cap with air intake, two adapter caps a hose mouthpiece and hose clip. The caps are the key to the system. The hose is standard size, so any normal mouthpiece, clip, etc, can be used. I don't like the clip and mouthpiece provided in the package, so I replaced them with Camelbak versions. (Note: in the photo above, there is an extra Camelbak mouthpiece that doesn't come with the SmarTube.)

Since a disastrous hydration bladder leak in my pack some years ago, I have avoided hydration systems. The SmarTube allows me to enjoy the benefits of a hydration system without having an unexpectedly soggy sleeping bag.
