    QMT Tube

    Tube with two quick connect adaptors, one on each side.

    My first reserviors
    As stated, easy use, easy clean.
    The U.T.A is a thumbs up. Just plug to the tube, connect to a tap, that's it! Easier way to refill.
    Only one down side: not low-profile reservoir.

    Currently we sell our new Low Profile Widepac LP only standalone. But feel free to combine any accessories (UTA, Magnetic Clip, Storm Valve etc.) with your favorite reservoir. All parts are available here for online orders on SourceOutdoor.com
    By far the cleanest and most reliable reservoir on the market. We have used and abused the Widepac 3L and it still keeps us hydrated like the first day we got it. Great value and is packed with features. A must have for every adventure!
