    Hydro Tanker 2L Top Fill Water Reservoir

    Great water reservoir, fits perfectly in my new sling pack. but took a little trial & error to figure out the valve: in-line or straight, is locked, right-angled is open. Tho I do wish there was a cap, and a hook to hang the reservoir on, tho I can probably MacGyver a velcro loop.
    Time will tell how long the opening lasts 👍

    Great bladder, would love to see more from it

    Got this bladder for use with my velox ii backpack for hiking around a could trails. Bladder works great, love the bite valve design.

    I would love to see a few more features on this in the future, or even on a more premium priced bladder from 3V. A quick disconnect on the bladder would be an amazing addition. I also believe I saw some of these had come with magnetic clips in the past instead of the current plastic hook. I would love to see a return of those.

    Great size

    I have a 3L platypus bladder I use in my large pack for big hunts. I got the 2L bladder and it is very similar to the platypus. Works great for short hunts.

    Not used yet

    I wanted the 3l but wasn’t in stock so I settled for the 2l

    Great piece of equipment

    Cheap Plastic!

    I loved this water bladder the first time I used it. But the second time I used it the two red prongs on the back snapped off and now the bag won't seal right, leaking all in my bag. Great backpacks! However, I will be getting my hydration bladder elsewhere

    Hi Randy,

    We're so sorry to hear about your issue with that water bladder. This is not a common occurrence for those reservoirs. If you contact us at: support@3vgear.com we would be more than happy to send you a replacement.

    Great products at great prices

    I love that the reservoir fills at the top. It makes life so much easier. All the items I have bought from 3V seem to be made very well and the prices can't beat beat unless you buy sub-par gear

    Perfect fit for your outlaw sling. would have given 5 stars but the swivel bracket that holds the hose is really cheap an fell apart before i got to use it.
