Mazama Hatch Tactical and Hunting Hydration Bladder Reservoir - Leak Proof Replacement for Backpacks - Extra Durable 30% Thicker Film - - USA Made Puncture Resistant Film

Very pleased with this hydration system and its performance. Materials feel substantial. Center baffle on 3litre bladder helps retain some space in your ruck. Hatch system works very well, I was able to easily open and close every time. Hose retain clip for MOLLE is a nice addition, even though I didn't use it. (use a ITW GrimLoc for hose retention)Just after purchasing it, I used it in a GORUCK Heavy (24 hour / 40+ mile) team endurance event.No issues during the entire event, even after removing the bladder from my ruck multiple times, multiple refills, and multiple times detaching the hose.This bladder held up to pretty significant abuse while in my ruck during the event. (ruck sack used for overhead presses, dropped, carried upside down for 1 mile, rolled over on, etc)For the price you can't go wrong. Similar hydration systems are easily 2-3x the price.Only complaints would be;- The hanging loop could be slightly larger. No real issues, just took a little effort to thread my ruck's hanging strap through it.- Not 100% certain, but it seems like the bite valve assembly could be pulled out/off of the hose. This didn't happen, but I was sure to keep an eye on it. Maybe it could be reinforced with a "clamp" of sorts, or small zip-tie.- Bite valve dust cover does not keep sand out while rolling around in the surf. (Not that this is "normal" use, but it happened) Easy to clean off though.All in all, I would recommend this hydration system to anyone, regardless of their intended use. If it can survive a GORUCK Heavy, it will definitely survive a casual backpacking trip.

-Never had issues with flow.-Bag can be hard to fill all 3l. You need good hand strength to hold the handle and fill. Took me a couple of tries. It is easier now.-Latch is big enough to add ice.-Not too hard to clean with cleaning kit.

So I feel it should be compared to the big competitor, Camelbak. The lid sounds and looks cool, but it is difficult to hold while filling. The handle is a big piece of plastic that there is nowhere to get your fingers behind to hold it while filling it, so I have to hold it from the sides. The lid with the lock is pretty cool, however, I do prefer the Omega. The lock is sometimes hard to get to open, especially when Im trying to prep my equipment i the dark at 0300. It doe not add any plastic flavor to the water. I had leftover water from a day or two ago and it still tasted fine. In addition, I like the bite valve functions.Its an okay product, but I am looking to replace it with a Camelbak, mainly because its a pain to fill in the dark in the early morning and when Im on the move, and thats when ill mostly be using it. Plus the opening is small so its hard to put ice in it.

Was looking for a hydration reservoir for a while.. read good things about Mazama systems (no taste, no leaks, lifetime guarantee) and came across this one at a low price for a 3L bag. Just received it, filled it, and currently sipping tasteless water. The insulated tube and cap are essential for my projected hikes in the coming winter months. Fits perfectly in my little 18L Osprey pack, so I’d imagine it would fit in any hydration-capable pack.The fill-port is big enough for ice and has a lock for peace of mind. The center baffle makes it low-profile and thus easy to slide in and out of a pack.I’m basically just stating everything it says in the description but I am very satisfied with this reservoir.All hail Jeff Loomis.

This is my second bladder bag and it is amazing. My first is a generic made in China and came with a backpack. This bladder bag is thicker, comes with an insulated quick release no leak tube, no leak flip open lockable lid, twist open mouth piece instead if bite style, with cover and can be mover 180 degrees for use on right or left side. Great deal for 25 bucks. I liked it so much I bought another.

I like that this has ribbing to keep it sturdy. I don’t love how the water tubing needs to be installed at the bottom because it is hard to manipulate. The opening being large is helpful for cleaning and drying.

Good bladder for my usmc pack. Overall I’m happy and would buy another if I needed one.Pros:Can be filled without tube attachedThe handle make filling easyFlip cap and lockLifetime warranty.Cons:mouth piece sucks, not a big deal I replaced it with a spare camelback one.The seal around the edges is rough. Hope it doesn’t rupture when I’m using it.

These are awesome. The tube is pretty good, although the best tunes are from camelback with the quick disconnect. But there are a close second. The bladder is what makes this the best out there. Really widh they made 1.5L bladders that are wide.
