MARCHWAY Tactical Molle Hydration Pack Backpack with 3L TPU Water Bladder, Military Daypack for Cycling, Hiking, Running, Climbing, Hunting, Biking

Great camelbak substitute for half the cost! Super durable, made of quality material. I was in the Air Force for 6 years and this is 100% better than the military issued bladders and backpack units they issued us! Im a stocky muscular guy and the pack is a perfect size not to big or small and has plenty of straps to get the perfect fit to conform to your body for when your exercising with the pack on! Seems very well insulated and I filled the bladder completely up with water and a full tray of ice and there is no leakag and it still feels perfectly conformed to my body not all bloated or combersum. Will definitely be able to do a wide range of exercises and activities with it comfortably strapped to my back. Super happy with my purchase!

I've had this for about a year as of this review. I mainly use for lawn work, and can't hardly get the lawn mowed without it. Also makes it easy to get the kids to drink more water when we're out doing stuff.Initially purchased for the large capacity, and the large opening. You want the large opening for cleaning. Being able to disconnect the hose at the bladder also makes it less awkward to clean. There are little dots and corresponding arrow on the cap, which took me an embarrassingly long time to notice. Those help get the cap sealed correctly, and it is a super great fit/doesn't leak. I don't use the belt strap, but it easily tucks away. Most of the time I don't even register that it's there.I didn't think much of the pockets at first, but have found them super convenient for the pool. Can easily get several bottles of sunscreen, phone, wallet, and keys in it. I also wondered why in the world you'd want a cap on the bit valve... until I took it to the beach! And the cap is shaped so you can use your teeth to get it on and off. I also wondered at that until lawn work left me with dirty hands.The rate of water flow encourages sipping vs gulping. At first I thought that annoying, but have come to prefer it. To the point it got me curios enough to look up sipping vs gulping water. Apparently sipping water is more effective in terms of hydration. Too much water at once and I guess the body just starts dumping the extra, but you lose salt and electrolytes. Which helps explain the headaches I usually get from lawn work (though I am in poor shape!). This just makes me laugh! At 45 years old to find I've been doing something as simple as drinking water wrong my whole life... Guess if I was that bad at it I wouldn't have made it this far though!Anyway, great product. I appreciate the amount of thought that went into it.

I wanted to wait till I put this bag to the test. I just got home from a 2,037 mile motorcycle trip. This bag was a lifesaver! I usually only had to fill it twice a day. It keeps ice very well, practically all day. We were traveling in heat up to 99 degrees. I never got dehydrated. I really had no need of the zipper pockets but I can see where they would be useful to a hiker. The only modification that I did was to raise up the hose clip so that it would not kink the hose when drinking at speed. I feel that this bag is far superior to the leading competition in quality and usefulness. Robert

The pack is great - just the right size, fits the bladder perfectly, a good balance between durability and light weight. The compartments are great - just the right size.The bladder is a disaster. Mine has a horrible, acrid, chemical taste and smell. I have washed and dried it half a dozen times. I followed the instructions in the condescending (but ultimately unhelpful) review entitled "How to Adult" and used a few drops of Dawn swished around and run through the system. I did this twice. I even thought that leaving it in a hot environment might induce the plasticizer or mold release or whatever to leach out faster. None of this worked, despite an investment of 30 minutes or more over several days. It still smells and tastes very acrid, making me think the plastic bladder did not fully cure, or that there is mold release or plasticizer migration. Whatever it is, multiple wash and dry cycles did not reduce the smell and taste. I will be substituting a Camelbak bladder for the one that came with this.But the pack itself is excellent and a fraction of the price for name brand 3L packs.

Perfect for hikes and rucks. The pocket is large enough to carry bear spray and the molly webbing is convenient for hanging things off it.
