    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.

    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!!

    Exactly what I needed

    Camping with 3 teenage Boy Grandchildren, one can never have enough water. The 3L bags with top filling quenches the thirst of these every 20 minute Sippers !

    Mark Haveman (Gualala, US)
    Tanks a lot!

    I like it!! easy to fill and easy to clean. As with any hydration bladder I have ever had it takes a while to get the plastic taste out of it. Any body have any neat tricks for that?? It works great with the Surge pack.

    Benjamin Mosey (Mesa, US)
    One of the best!

    These reservoirs are top-notch. High quality materials, great design... well worth the cost!

    Like the top fill

    Well made. Top fill is awesome

    Jordan Reese (Silver Spring, US)
    Well made

    Well made product but I'll be getting the 2l size for my outlaw 2 sling bag, this 3l is just a tad too big to be comfortable in the pack without squeezing it in

    Noe Lerma (Houston, US)
    Hydro packs

    We just received our 3L & 2L hydro packs. They work great with our existing packs. Very well made and the price was great too.
