    Great product. Works like a charm. Fits great into my 3Vgear sling pack.

    Love it.

    At first my fiance thought it was a little much with the cap and the open close valve. But considering we were on a beach the cap actually did a really good job keeping sand. Off the mouth piece. I also really liked how the whole top folded open to fill it. Was about to fill pretty quickly that way. I only wish it were more one handed friendly. Trying to hold the bag and fill it up was a little problematic but that probably has more with what we were filling from than the bag itself. I hope this review was helpful. Also I wish you guys made a size that would fit the posse bag.

    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.
