Platypus Hoser Ultralight Taste-Free Water Reservoir/Hydration Bladder, 3-Liter

Bought 3 of these for a backpacking trip in Grand Canyon. No leaking at all and taste is just fine. Perfect!

This is my third one over the 11 years of backpacking, durable and work great always.

The Hoser was the only system that made sense to me when I first got a bladder in 2002. The hose can just be moved to another bag when the first empties. Weight is another advantage as there's no large heavy lid in the side of the bag. It is similar to systems using disposable bottles in weight. I seem to buy a new one of these every 10 years, so it was time for the third.The bags never grow crud, but after 6-8 thousand miles, they can wear out. I recommend against folding the bag for a longer life. The hose and bite valve need to be dried out if it's not being used, so there is some care required. (Pop off the bite valve and hang up the hose to drain.) The hose is usually a couple inches too long, but it can be cut down on the barbed connection side. Careful not to cut down too much, it can't be added to as easily.I managed to get a leak with the first one once, but it was user error and they've been redesigned to reduce the chance of that particular error. (Longer threading -> less chance of cross threading.)

This fill spout is smaller than others I’ve had in the past. Check the images before buying, but it does come down to user preference. You can use the threads to do some water or filter connections, etc.

I got the 3 liter version because I always have the option to carry less if I choose, but I like having a full 3 liters available for use. However, you will need a decent sized backpack to hold the container.The clean taste thing seems reasonably true after a period of time, but the first few times I could taste/sense the bag even after washing the best I can.Due to the size of the bag and the small opening, it is pretty much impossible to scrub out the interiors of the components. I have been hanging it upside down after using it and rinsing with soapy water and I have not seen any molds in the straw or the bladder. I am keeping hope that this will continue.Overall, I am happy I upgraded to the bladder from using bottles when hiking. It is very very nice to take a swig while walking then having to wait for a stop and taking off my gear to get to the bottle. I am surprised it took me this long to get to using water bladders. I used to think it was a bit gimmicky for weekend warrior hikes, but I stand corrected.

I used this for a bike packing trip in Joshua Tree. It was ~95 degrees (F) the whole trip, so a lot of water was needed. This thing was a lifesaver. Fit it in my triangle bag on my bike and wrapped the tube by my handlebars for easy access. No issues the whole trip.

I have purchased these two times and never will again. Both times they failed in the same spot, the nozzle where you suck water out of. The one I most recently received did not have any adhesive holding the nozzle to the tube and it popped right off when I went to use it on a camping trip This is inexcusable for a peice of plastic with a tube that costs $40. This is not a one off issue, both failed the exact same way.

I bought this bladder for my husband because his taste like crap. I have had my own platypus bladder for over a decade and it’s still going strong. If you use it on a regular basis, you do need to clean the mouthpiece thoroughly but mine has never popped. I don’t know if everyone knows this, but it also connects perfectly with a sawyer water filtration system. So you can fill up a sawyer gravity bladder and connect it to your platypus bladder and walk away and do other projects at camp while it fills! brilliant!
