Description

A BPA-free hydration bladder for your hiking backpack.

You have a backpack and you'd love to stash a water reservoir with a drinking tube in it for quick, hands-free hydration on the trail. Grab the Platypus Hoser Hydration Bladder. Platypus made this reservoir with 100% BPA-free material, and added a SlimeGuard antimicrobial treatment to the inside so you won't end up with unidentified black bacteria camping out in your water bladder. The HyperFlow bite valve hooks you up to fast-flowing water, while the modular design fits into most backpack hydration sleeves.

Sturdy.

  • Familiarity: I've used it once or twice and have initial impressions

Connections are tight and there haven't been any leaks or annoyances. Seems very well-built.

Platypus Cust. Service is Awesome

  • Familiarity: I've put it through the wringer

The bladder is very durable. I stepped on my connector cap and broke it, but Platypus was very nice and sent me a new one.

Hydration is a Full Time Job

  • Familiarity: I've put it through the wringer

I live in the desert and I'm super active. Not easy to keep up with hydration. I fill this every night and keep it by my head, because if I don't even have to sit up I will actually drink when I wake up thirsty. I also carry it every time I hike somewhere short just to catch up with hydration. Great when driving long bumpy dirt roads too....

No leaky

Platypus makes great durable products and this is definitely one of them. I have been using mine for about 2 years now and have never had any issues with it.

good bladder

  • Familiarity: I've used it several times

I like it so far. Some times you feel like your sucking a tad too much air. But i have never owned another bladder so... Water tight seal so far, and I like it.

Hoser Design Flaw

  • Familiarity: I've put it through the wringer

In the early days, the 2 liter Hoser had a flat bottom so you could conveniently set it on its base for filling (like the platy bottles have). This was a positive feature which reviewers liked. The newer version of the Hoser has the ridiculous new "floppy tab" bottom (I am guessing it is cheaper to make) and now they will not sit stably on the ground for filling. This is a massive design flaw, which I have brought to CD's attention in the past, but it's being ignored. They need to bring back a Hoser with a flat base (like the bottles), or I will have to switch brands. Too bad, because everything else on this product is good.

I've used my 3L Hoser for almost 5 years and have never noticed any problems due to lack of "standable" design.

What are the dimensions of the bladders?...

What are the dimensions of the bladders?
I'm surprised this information is not listed.

Hey Griegor
Thank you for your question! I found the information below from Platypus's product specs on their webpage.

1 Liter: 5.25" x 11.5"-- (13.5 x 29 cm)
1.8 Liter: 6.75" x 11.5" -- (17 x 29 cm)
2 Liter: 6" x 16" -- (15 x 40.5 cm)
3 Liter: 7"x 16.5" -- (18 x 42 cm)

Thank you so much!
How simple. Usually I think of that.

3L Platypus Hoser Rocks!

  • Gender: Male
  • Familiarity: I've put it through the wringer

I'm a big fan of Platypus products (see my reviews of their GravityWorks water filtration/storage system, Platy SoftBottle water bottle and Shut Off Valve). I bought my Hoser in 2009 and went with the 3L version (3.8 oz) because it's nearly as light as the 2L and 1L versions (3.6 and 3.2 oz, respectively). For comparison, CamelBak's 3L Antidote Hydration Reservoir comes in at 7.0 oz. When I backpack, I try to limit water-weight and carry only 1L at a time. With the 3L Hoser, I have flexibility to carry more, if needed (i.e. if water sources are fewer and farther in between). I used a black Sharpie to add marks indicating when I've filled bladder to 1L or 2L (see pic). Otherwise, you need to add water to bladder and then cap and invert to see how much you've got!

I only carry water in my hydration bladders (no Gatorade or other energy mixes, etc.) and I clean and dry thoroughly immediately after each trip - so far, no "funk" problems for me. In my experience, Platypus products are very durable - mine take a beating and I've never had a leak. These bladders are highly recommended!

3L Platypus Hoser Rocks!

Take care of it!!

First, I love the design, no lid that is, at times, impossible to open...super light, and bite valve DOES NOT LEAK, which is the reason I changed brands of bladders. Second, I didn't clean it after first use, and did have some pretty serious stink and nasty taste to it. I then cleaned it, using only soap and water, and put it in the freezer to store it, then next time I used it...NO STINK!!
So take care of it properly, and it is a terrific hydration system, miles above the other leading brand...

Failed on first big trip

  • Gender: Male
  • Familiarity: I've used it several times

I purchased the 2L and used it several time with 1 liter. Put 2L in it and 150 feet out of my car going into Congaree NP in started leaking. Unpacked my GG Crown VC60 and found that the lower corner of the hole that you hang it by had pulled apart. Had to hand carry it 6 miles to camp. Not sure if I'll try another, truly liked it.

does the job!

simple and effective

  • Gender: Male
  • Familiarity: I've used it several times

This bladder is simple, effective, and priced correctly. Its simplicity cuts ounces compared to other versions on the market. They don't last forever, but I've enjoyed using this product on all of my hikes.

Great Bladder

  • Gender: Male
  • Familiarity: I've put it through the wringer

I was aprehensive buying a Pltypus and bought this expecting it to break or leak after a short while. Lets be honest, they feel "cheap." I have used this many times and it has never done me wrong. Would highly recommend this for your backpacking bladder needs. Also, I like putting it upside down from what the picture shows so the cap is on top. It still works that way and runs less risk of leaking all over everything (only works for the 2L, not the 3L).

Responded on

How do you get water to the hose? I have the 2L as well but when I turn it upside down the water is not close to the hose.

Simple

I love this bladder! It is BPA free which is a plus. It is easy to use, easy to clean and very durable.

Generally Satisfied

Let me start off by just saying there's nothing extraordinary about this hydration system. If I had to sum it up in 2 words it would be 'simple' and 'functional.' This is saying a lot. I am overall very satisfied with this system. It does what I expect it to do and it does it well.

As far as cleaning goes, it's not as hard as everyone makes it out to be. Use your brain. If you leave it with water in it and you don't clean it after every use, guess what.... it's going to suck. If you take care of your gear it will take care of you.

Final say:
I will buy this again when I need to replace.

Best for the money

I'm sure you can get a better bladder; but not at $25. I'm on my second or third in about 8 years. I just rinse with dish soap occasionally and hang dry.

Great bladder

I've used this bladder for a year now in every season under every condition. It's price is relatively low when compared to similar products however the bladder's quality isn't compromised. It's tough, easy to clean and dries quickly allowing for funk free taste every time. I like the hard plastic loop at the top of the bladder. It comes in handy for storage or camp use. I would recommend it to friends and would buy another Platypus product from my experiences with this one.

Works well, but a bit of a pain to clean, and durability can be an issue

These do their job well, but cleaning them after you get home isn't the easiest. I prefer to rinse out or scrub a wide mouthed Nalgene. Having to take the time to scrub it with a long, awkward brush, and/or use a few drops of bleach... its not worth it to me. But that's personal preference. If you like sipping on the go then the bit of maintenance might be worth it for you.

I've never personally had one of these leak or burst, since I only owned one for a few days, but I have seen them critically fail at bad times for other folks. It was personally enough for me to not ever be interested in taking a chance with them.

Also, if you like a nice hot water bottle in your bag on a cold night... forget it with these. They won't handle the heat, and I wouldn't trust one of these in my down bag any more than a mountain lion.
