Platypus Hoser 1.0L Hydration Reservoir
Particularly lightweight and tasteless minimalist drinking bag with a high flow rate. This drinking bag has a self-sealing bite valve that has a 30 % higher flow rate than the previous hoser from Platypus, while retaining features such as low weight and minimalist design. Weight-conscious backpackers will particularly appreciate these advantages. It is neutral in flavour and free from BPA, BPS and phthalates. The semi-rigid partition wall keeps the bag open and ensures faster drying. Incorporated silver ions protect the drinking water from mould and bacteria. A high-mounted quick-release fastener on the hose enables quick filling and emptying. The leak-proof closure valve and a hose diameter of 8 mm contribute to a faster flow rate.

We bought a pair of these for long hikes. On our first day hike using these, one of them split open on the side. Looking closely at them, you could see that the seam was much thinner on one side than the other; a manufacturing misalignment defect. It was thin enough that from normal use it split open. I was able to repair it enough using a lighter and melting the seam back together (had to do that twice during the trip) so all was not lost, but it's no fun having your backpack fill with water...We ordered replacements through here and the ones we received seemed much better at the seams, so we're happy to try it again.When well manufactured, these reservoirs are amazing. The tube is stiff so it won't pinch/kink easily, the bite valve is very well made and doesn't ... MoreWe bought a pair of these for long hikes.

The strap clip is kind of finnicky but once you get it sorted out it works well.Note that it doesn't come with a standard cap which is useful to buy separately if you want to use it to carry water.The Hoser comes in 4 sizes, but the size/weight in use is obviously just the water, so I'd recommend getting the largest size you can afford for maximum flexibility and convenience.

I bought two of these for me and my son. Mine started leaking as soon I filled it. They did a poor job of gluing the hard plastic neck to my bag, which allows a thin, steady stream of water to shoot out. Too bad I didn’t test this before being at the trail head. Lucky I had my Nalgene bottles with me.My son’s worked fine. He liked the fast flow tube and valve. It’s hard to dry though, since there’s only the bottle neck to air it out.

Chose a Platypus reservoir as I'd had my old one for 20+ years, great when snowboarding in my backpack etc. Recently gotten in walking, so decided to freshen up my gear, and having been so impressed with my old Platypus, stuck with the brand.New one failed during the very first use. Filled it with less than 2ltrs of water, and as I was putting it into the compartment on my back pack, it split along one seam, about an inch long, and dumped most of the contents into my bag.Not impressed. Not sure if it's a manufacturing fault, or just a decline in quality but not great at all.

This is the second platypus I have bought as I think for how hardwearing they are they are the best on the market. However..... There is a major flaw with the item that has caused me concerns with both of them. The bite valve is a really poor design. The first one I had was out in the mountains, put the rucksack it was in down and must have pinched the valve, as there is no way of stopping the water flow, It flooded all over dry kit and lost 50% of water. Should have learnt my lesson but with this one just forgot what happened, could have been a lot worse as the bite valve again must have got pinched and all of the water flooded out over expensive photography equipment. More by luck than anything else nothing got damaged but this is a really bad design. Have now ... MoreThis is the second platypus I have bought as I think for how hardwearing they are they are the best on the market. However.....

Much better design. Great water reservoirs but the bite valve design needs a serious rethink.
I guess a water bladder is fairly straight forward but the design of a good water bladder can actually save your day. I give the Hoser Reservoir a 3 Stars review which I believe is not super good and not super bad, it's right in the middle really.what I liked:- fairly straight forward design where not much can go wrong- I liked the way they made the out valve at an angle because I have two packs I can use this bladder inside and both have a different route to get the hose out of the pack, one on the side, the other at the bottom - which this bladder make it easy for me to route.- the material used to build this bladder is of common grade, nothing really heavy duty and I guess keeps the weight down.- all component worked fine out of the boxWhat I don't ... MoreI guess a water bladder is fairly straight forward but the design of a good water bladder can actually save your day.

The way they glued the mouth piece is not the best way to go when your pack has a tiny hole to route the hose out of the pack. Is it the fault of the pack maker for making such a small exit holes or is it the Hoser Reservoir for not having engineered this variable in their after market bladder???? I let you decide for yourself.
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 :)
I absolutely love my new 1 liter Platypus. It has so many improvements over the original Platypus that I have been using for several years now: improved position of the nozzle on the side of the reservoir instead of in the bottom middle, the ability to hang the reservoir (before it always fell to the side), and the increased flexibility of the plastic. The only thing I miss is having the metal clip that used to come attached to the hose. I don't understand what to do with the current hose clip (you can attach it to the hose, but I don't get how you can attach it to the pack, and I can't find any instructions about how to do this).
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 ... MoreThe best things about the Platypus bottles and reservoirs is their lack of a plastic taste.

I have 3, 2, and 1.8 liter hosers (the 1.8 is a better shape for a short bladder pocket than the 2)
The material is very good quality, I don't taste the plastic used. Though I have a few issues with design:1. I have to take off the hose to refill it. This is a pain when doing a long hike, taking up time and making organization difficult. This also makes it harder to clean.2. There is no cover for the mouth piece. Whenever I have to set my bag down it gets dirt and dust all over it.
I like the hoser because it is slim and fits in my slim bicycle hydration pack. Other hydration systems are too wide or large and have a strange mid-hose attachment that occurs in the wrong spot. I like the platypus version because the hose is sleek and easily slots through the pack slots and also it is slim but still holds a lot of water. with only one spot to refill and attach there is reduced chance of having a leak. Simple and reliable- just what you want in a hydration system.
