    Hydro Tanker 3L

    I have used this water reservoir and it worked wonderfully. It was easy to fill, the reservoir clamp is attached and was a big plus to me. Good design

    3.0 liter hydration

    Just got this for my paratus 3 day pack. Looks good and will be used year around.

    DeniedAccess (Atlanta, US)

    I purchased both the 2L and 3L at the same time to see which one I liked better. In this heat wave we have had the 2L seemed to get empty much faster while the 3L lasted the entire day. It does take up more room in your pack so make sure you plan ahead with the correct size pack or it will be to big.

    Works great!

    This is my first time buying a water bladder/camelback. I'm very happy with my purchase.

    Tim Loya (Corpus Christi, US)
    Great sealing system.

    Most water bladders work just fine but are a pain to clean and dry. This is the first bladder I've seen that is sealed the way it is and it allows me to have full access to the reservoir for cleaning and hold open with an apparatus to allow it to dry fully (to avoid those funky tastes that develop over time. Definitely recommend, and highly too.

    I have made a couple of purchases from this company so far. Their products great but their customer service is better!! Thank you, again.

    Hydro Tanker

    The tank looks very good quality but it is too big for the sling bag I bought it with. My mistake, but a two litre tanker would have been better for me.

    Jennifer Martin (Raleigh, US)
    Great quality, fits perfectly in the paratus 3 day backpack

    Can't wait to get my paratus bag and reservoir filled up and take them for a spin.

    Michael Silva (Houston, US)
    Awesome Water Bladder

    3L Top Fill Water Reservoir works great, no leaks, water tastes fresh with no plastic or rubbery taste after sitting in reservoir. The reservoir also balances nicely in the compartment in kit. Good Staff!!
