    I currently own a small Camelbak reservoir. It only has the bite valve, a problem I've had is that when stepped on or pinned underneath weight, it will leak prodigious amounts of water everywhere. I nearly soaked my laptop in a backpack because of this recently (though I was also traveling via plane, pressure and physics and such didn't help).

    Question is: how well does the cap seal and protect against spillage if the valve/tube is accidentally squished? Are there versions that have another stopper valve thing that's toggled?
    A shopper on Jul 3, 2017
    BEST ANSWER: The Monoprice reservoir is the best I've used. On the hose, in addition to the bite valve, it has a rotary cutoff valve. I have not been able to get it to leak at all when the rotary valve is closed, beyond the tiny amount of water held in between the two valves. But I haven't tried deliberately squishing the hose... :-)
    Does this bladder have a firm backing on it like the Osprey so that the fluid does not bunch up at the bottom?
    New User U on Oct 6, 2017
    BEST ANSWER: It does not have a firm back but has stitching vertically down the middle that helps with the problem you describe. I have used it on at least 5 weekend trips and love it besides the taste it gives the water.
    Are these made in China?
    David A on May 26, 2017
    BEST ANSWER: Thank you for your question. Yes, these reservoirs will be made in China.

    Exactly what I was looking for
    I bought a full sized hydration compatible backpack that didn't come with a hydration pack. As you may know, the name brands are pretty expensive and I had a hard time finding a suitably larger one. Even searching online I'd find ones with smaller mouths or the zip kind and still more than I thought I needed to pay. This is wide-mouth and is super easy to use. This was exactly what I was looking for, the right size, at a fraction of the cost.

    Nearly Perfect Water Bag
    We had recently purchased larger day packs with water bladder sleeves and found our older bladders weren't cutting mustard. The price of this bladder is pretty unbeatable and the system works nearly flawlessly. I would give a hardy recommendation.

    PROS: Insulated Tube
    Mouth piece guard/cover
    Automatic valve closure at base when tubing is removed
    90 degree elbow at mouth piece
    Wide flat designe

    CONS: Narrow tubing reduces the water flow a bit more than I'd like
    Some leakage at the joint with the mouth piece (no leakage with main valve us in the off position).

    Did everything I need it to and more.
    This pack was recently purchased for a safari trip. The 3L volume was well appreciated when walking in the bush. Looking at other packs in an outdoors store, this one seems to be made in the same factory as one of the top name-brand ones and contains the same features and appears to be made from the same materials. The handle under the opening is well placed for filling. The valve below the mouthpiece is great for ensuring that it is off. The silicone mouthpiece didn't leak for me even when the valve was left on, and the mouthpiece cover was great when I went to the beach to keep the sand off the mouthpiece. I also found the quick-connects valuable when clearing water out of the hose.

    Pleasantly surprised
    This bladder is awesome. For the price, I was expecting something of lesser quality. Boy, was I pleasantly shocked! And to top it off, it has all the bells and whistles that the much higher priced bladders on the market have. You can't go wrong with this one.

    Quality, but the taste.
    The reservoir and tubing seem to be well made. The seams appear they will hold up to a few years of abuse.

    I had no issue with the mouth piece leaking, like some other reviewers. Also, It is nice the hose is insulated.

    I found the reservoir gave the water a stronger taste than I was expecting. This is after several rinse outs and even trying a short bath of vinegar and than a short bath of baking soda (a strategy other websites suggested).

    The taste did not bother me when I was thirsty on the trail. Maybe it will disappear with time. I am not experienced with hydration reservoirs, so maybe this is to be expected.

    Great Product
    Is well made, heavy duty, was very happy. The mouth piece was really cool too. Have been pretty happy with the Monoprice products so far!

    I've loved it for the month I've had it -- There was a slight plastic taste at first, but that's every bladder.

    -3.0L is a really good size.
    -Everything is great quality.
    -Has a hook at the top for hanging in backpack.
    -Has a lock-off valve to prevent drips
    -Easily disassembled for cleaning/drying

    -The cap over the blue bitepiece has weird tension on it, and won't easily stay on.
    -The bitepiece cover makes it very difficult to slide the blue bitepiece back on the tube

    The insulated tube was a nice thought, but it doesn't keep the contents of the first draw cold...I suspect that the black sheath retains sunlight and actually heats it up more than without it.

    Great replacement bag
    Like the functionality (and the price) of this bag. There are several details (large opening, baffled construction, no leak disconnect) that make this a practical replacement/addition to your hydration bag.

    The only knocks are that the large opening makes filling the bag without spilling a challenge, plus the cover to the bite valve--wish it was easy to remove.

    Good water bladder for hiking, camping, and other activities
    Worked great on my Inca Trail trek this week. The bladder is sturdy (it held up better than the name-brand bladders my friends were using) and the tube is insulated against cuts and weather. There’s an internal brace that keeps the bladder flat when full, so it fits perfectly in the 32L “tactical backpack.” The mouth piece guard is a nice touch (I remember on my old bladder system the mouth piece got filled with grit when I took it caving). I may even take it kayaking next summer just to see if it works well for that.

    Why not five stars? Well, the capacity is technically 3.0 liters, but due to the size of the fill opening it’s effectively only 2.5 liters when filling it on-the-go (which is actually perfect in Peru since that’s a common water bottle size you can purchase). Also, the mouth piece comes off a little too easily, requiring you to fit it and the mouth piece guard back on simultaenously, which takes a minute to figure out on the first try.

    Still, for the price and the capacity, this is a steal!
