Let it flow, let it flow...I used to use a camelbak, but when filled with just water it tasted like plastic no matter how many times I washed it. Enter the Platypus. No plastic taste whatsoever. The water tastes pure and I dig that. The bite valve is a little different than a camelbak, but I'm used to it now and even like it better. I only use water in it without ice, but with the small opening it might be hard to add a lot of ice. Also cleaning it isn't as easy as a camelbak because of the opening. I also wish the hang loop had a clip to use with all packs. Even with those little quibbles, I love this thing and will gladly buy another when this one is done.

Flexible systemI have been using platypus water bladders for years and in general very happy with their performance. I am not a big believer in storing water inside my pack after a bad leak with a different brand bladder. So I use an outside pocket for my Hoser. No problem keeping the hose under control. I like the ability to use different size bags as needed. I usually fill a one liter bag for hiking and carry empty two liter bags for in camp use. When needed I can swap tops and have the larger bag as a hoser. Still fits in Side pocket. Yes it takes a few days to dry these. I find that a paper towel stuffed inside for the first day really helps get the drying started. Also I have swapped out the bite valve for a different brand since I like magnetic instead of spring clips.
But so far no bladder/water system seems as light and as strong as the platypus bags.

Great system!I am an avid trail runner and because of that, I have tried many different hydration systems to find which works best for me. Platypus I found was the best yet, it feels thinner inside my pack and sits well against my back, I don't even know its there. You also do not have the annoying rubber taste that some hoses have, making the water taste much better.
It is also very durable in its design, during races I have to quickly open and close the bladder to refill it multiple times during the race, and the wear and tear I have put on mine is quite significant, but it has held up better than any of my other bladders.
I would highly recommend this product

a great reservoir at a competitive price.this is a great reservoir. i got a camelbak hydropak from goodwill for 75 cents, but it didn't come with a bladder so i started looking. i was looking for something that would be light and durable, but most of all, wouldn't taste like plastic. price also played a big part in the decision. after about a week of looking around, i landed on 1.8 ltr platypus they have so many size options - it's awesome!. it fit all of my criteria and it was the cheapest by 5 or 10 bucks. this was also my first moosejaw purchase, and i was thrilled. i will definitely order from these guys again, and the sticker they sent me is already being displayed on my car. the only issue with this reservoir is i'm n

One of the few ladders that will fit in my Arc'teryx pack.I mainly use the Camlbak 70oz For my daily hiking needs. I bought this blatter because it was one of three that can go into the zippered bladder sleeve on the Arc'teryx Altra 65 pack. The main drawback to this bladder is that it has a very small opening for filling. They are made of a of very durable plastic that has not given me any problems with punctures and seems highly resistant to them. I prefer the eCamlbak Big Bite mouthpiece and after talking to the platypus rep I tried to change out the mouthpiece on the hose. In spite of what I was told by the rep these mouthpieces are not interchangeable whatsoever.

Great reservoir, no taste or smell, and no leaks.I've been a hiker for a while now and have always used a simple Nalgene bottle, but finally gave in and purchased this 3L Platypus reservoir to go in a reservoir compatible day pack I already owned.
My first issue was that the sleeve in the day pack was too small for this enormous water bladder. Once I got it situated in my pack and routed the hose I was all set. The advantage of course is that when I want a drink I don't have to try and contort myself to reach for a side pocket and the Nalgene bottle, I can just pop the hose into my mouth and bite down to get a drink.
Now on to reviewing the actual reservoir.
The Hoser is a lot like all the other water bladders on the market, it has a large size bladder, is made of BPA free plastic, and does not impart a taste to the water you've stored in it. I like the larger size of the Hoser which at 3.0 L is one of the larger ones. It does make things difficult when getting it into your pack but the nice part is that I only have to fill it once, and maybe carry a single Nalgene bottle as a spare depending on the hike distance and environment.
There were only two issues that I've run into with this bladder. The first being when you fill it up. The opening for filling the bladder is a bit small (about the size of a plastic water bottle cap) which makes it difficult to completely fill the reservoir. And cleaning and drying the unit is also affected by this same issue.
Once you are done using the bladder and are ready to clean it and put it away you have to contend with the same small opening. It can take days for me to completely dry out the bladder so I can put it away. I have tried coming up with different tools to prop open the bladder but inevitably there is always a bit of moisture still inside that stubbornly doesn't want to evaporate.
Most recently I decided to try freezing the empty bladder and leaving it in the freezer until I need it next. We'll see how that works when I go on my next hike.
On the plus side of this bladder, I like the design of the bite valve. It takes getting used to as you have to bite down just right to get the water to flow, but I have never had an issue with leakage. Also, I've hiked with several friends who have competitors products and at least once a hike someone has a problem where their reservoir leaks in their pack. I have never had an issue with the screw on filler cap leaked. I have seen on some of the competitor models with the larger opening that they don't always seal as well.
This unit has a small 'loop' at the top which you can use to clip the bladder into a pack and there is a metal clip on the hose so you can position the bite valve for easy access.
There are also a variety of accessories offered by Platypus such as an insulating sleeve for the hose. I have found once or twice that if left unprotected on a cold weather hike the hose can freeze up and then the bladder is useless.
All in all this is a great product if you are planning on doing long hikes where there is a limited supply of fresh water.

Great hydration system, just don't over tightenBought the 2L for a trip to Yosemite. Did the Half Dome hike and Mt Conness. Worked really well for the entire trip. Bought an extra cap to make it easier to change between my other Platypus bottles without having to re-thread the hose through make pack. One problem I did encounter was over tightening the hose did lead to a leak. Just had to test it before I put it back in make pack. ,,,,I have two other Platypus bottles and I can't imagine what i would ever replace them with. Did I mention that my buddies Camelbak ended up with a pin hole?

Versatile Minimalist BladderI've had my Hoser for many years now and love its minimalist design, which also lends itself to being very versatile. I typically use my Hoser backpacking because it is very lightweight and, using an attachment Platy makes to hook a filter hose directly to the bladder, very convenient for one person to fill with a filter. Once at camp I pull this bladder from my pack and hang it from a tree to fill a Platy bottle for around camp and use it to dispense water for water for cooking, washing, etc. and it never lets me down. All in all a great quality product that is extremely versatile and lightweight.
