    • Perfect water bladder
Size: 1.5-Liter
No weird taste Drinking-Water flows easily and generously Comfortable mouth piece Secure on/off lever for water flow Good closure at the top of the bag - Top plastic closing piece is attached by a string so you can't lose it No leaks No complaints I just got this today, so it hasn't gone through the test of time yet, but so far it is excellent! : ) ... show more

    • Great lightweight bladder.
Size: 1.5-Liter
Another great product from these guys! Closure is watertight and foolproof. Shut off is handy to prevent leaks when not in use. Very easy to clean and dry.

    • Rugged and gets the job done
Size: 1.5-Liter
Got the 1.5L version of this to replace several no name brands that I had tried that ended up leaking in various ways. Its quite hefty and made of a nice thick material that gives you confidence it won't leak. It seals tight. The hose is very robust and solid, but perhaps a little long(?). No plasticy smell, although I did fill with vinegar and leave it overnight before using the first time (after rinsing it out thoroughly of course). Had trouble getting it into the bladder pocket on a small Osprey Daylite pack as its fairly wide, but once you fill it with water and shake it into place it fits fine. Cleaning seems to be a bit of a problem. Having a hard time getting cleaning liquids to drain through the hose easily to flush it out compared to other types. I also ended up using a jury-rigged device to keep the bag open to help it to dry out when washed. Water droplets seem to want to stay in there forever! Overall a good device and I will probably buy a second one. ... show more

    • So easy to use
Size: 1.5-Liter
Easy to use, easy to clean and dry, no weird smells, all the pieces parts work great. So much better than my old thread top camel back bladder - love the slide-closure style.

    • Great product, love the slide lock and valve
Size: 1.5-Liter
Got the 1.5L and fit nicely in my backpack with enough room for sandwiches when hiking. Love the valve that allow water to come smoothly. The slider lock is a huge plus, making sure the bag is completely locked and that water won't come off.

    • Works great, like the quick disconnect.
Size: 1.5-Liter
I put this through it’s paces and with the exception of freezing up on an 18 degree morning this past hunting season the hydration unit worked flawlessly in my Badlands 2200 pack. The bladder does not perfectly fit my back, but is very workable. I like the volume of this bladder, especially for my pack which the manufacturer bladder is 2l (you could not find a Badlands bladder this fall, 2020?). I did not have any water leak out of this despite laying the bag down numerous times. Getting the bladder dry after usage and before storage is the only negative, but cannot say that I have had or seen a bladder that was great for that!! ... show more

You must use 3/8 id fittings if you add any quick fill accessories .Well built unit, easy to clean.

    • Plastic takes a beating; love the seal
Size: 1.5-Liter
I hate giving 5 stars to anything anymore because those reviews appear to b paid or fake. But I’ve Used the 3l for over a year; I’m an avid hiker and showshoer (blow the water back to the bag and tuck the tube in my coat). I used this to cross the Grand Canyon in a day (Rim to Rim) meaning I was adding water directly from what can be described as the same spigot you’d connect your hose to—so powerful water flow. LOOOOOVE how perfectly it seals; the ‘abuse’ it can take. Will definitely get another should I get a little too abusive. (When I filter water I do so in a nalgene then pour it in the bladder) ... show more
