The best one we have used

Great lightweight and easy to use reservoir. Durable and we like the bite valve versus the one u have to manipulate to open

$ well spent

Beats heck out of the jury rigged soft-bottle I’d been using. Ensures I stay better hydrated. Light as heck. Tip: Just ensure the hose, where it exits the cap, is routed in the plane of the reservoir and not at an angle.

Lasts forever, amazing product

I have had my Platypus Hoser for more than 15 years now and it still works great. It's the two liter version, very similar to this one. No complaints ever, easy to clean, light weight, and very durable. My version even has "patent pending" still on it. And a logo with a Platypus illustration, which I love! Thanks @Platypus for all these years of joyful and well-hydrated hiking and biking thanks to the Hoser :)

Lucienne

On my holiday in the US I bought an new hoser reservoir 3L in an outdoorshop. Unfortunately it turned out that the connecting part was ruptured, must be damaged when still in the package. So when I put in water it sprayed out. Unfortunately I cannot use it because of this leakage. And because we are travelling I also cannot go to the store I bought it.

Leaky Bite Valve

Unfortunately this bite valve just doesn't seal and drips right from being brand new. There is no need to bite it really, it just drips everywhere. I had a better version 20 years ago, blown away that this design is currently being sold. I do appreciate it is medical grade silicone, but not helpful if it doesn't keep water in the hose until it is needed. I don't think the valve cover would even help as it would just fill with water.

Great product. Great Support.

I purchased 3 of the 2.0 liter Hoser Resevoirs and 1 happened to have a small leak after a couple of uses. I sent the reservoir in and received a whole new replacement without any issue. I have other Platypus bottles as well and they have been working great. Very satisfied.

Wish I hadn’t bought it

The bag doesn’t seal well and is nearly impossible to dry out after use. Should have opted for a model that folds to seal.

No bad taste, light weight

The best things about the Platypus bottles and reservoirs is their lack of a plastic taste. The Hoser is lightweight and stows easily when empty. If you use it for liquids other than water, you might prefer a zip version as easier to clean. One caveat - they don't dry readily, and the narrow mouth preempts being able to wipe the inside with a cloth. I bought an inexpensive aquarium pump and insert the tubes into the reservoir to dry it more quickly. I also have replaced the bite valve on some of my hosers with ones that have a shutoff valve, as if you set the pack on the bite valve or sit on it, it can leak - but I still think the advantages of neutral taste and light weight outweigh the other issues. I have 3, 2, and 1.8 liter hosers (the 1.8 is a better shape for a short bladder pocket than the 2)

Everything you need, nothing you don't

Great bladder. It's simple, well made and easy to use. The hose to bladder connection is a screw on, which I prefer over a quick connect snap in as there isn't really anything to break.
