    Platypus Hoser 3.0L Reservoir - 100 fl. oz. is rated 4.375 out of 5 by 16.
    Rated 4 out of 5 by from Good reservoir I have used this on multiple occasions, mostly for day hikes, though I will also use it for multi-day trips in the future. I bought this because it was the simplest, most "genericly shaped" 3L reservoir, as well as cheap. Like most of the other reviewers, I like the size, lack of plastic taste, the hang loop, etc. The cap is also the same size as a 2L soda bottle, if you want a cap, you don't have to buy the brand-name caps for this bag--just get a 2L bottle of soda from the store and use that cap. =) Although these do not prevent the product from functioning well, I might like to see some changes in the cap and bag shape. The cap could be bigger, since the narrow cap is a little difficult to fill without getting water all over the outside. The narrow opening also makes it a little difficult to dry. It takes me about a month to dry this out and usually I end up using it again before it gets completely dry. As for the shape, at least in my day pack, the length is right, but when full, it creates a large lump inside my bag. It's a bit annoying to pack other things into my bag with that lump there. There is space on either side of my pack's spot for hydration packs, so a wider bag would hold the same amount of water but not protrude into the backpack's main cavity as much. I would also add another loop near the opening so the bag is easier to hold while filling. Anyway, it's still a good hydration bag.

    Rated 5 out of 5 by from Better than bottles I have the my platypus for a few years now and it has been with me on 20 or more multi day backpacking trips in the sierras. The main thing I am impressed with is its durability. I can set the bag on granite, pine needles and many other surfaces that you would imagine causing leaks but it has withstood all the abuse. The bite valve does not leak while hiking. Make sure to keep the valve in a safe place while driving to your trailhead (if another pack is leaning on the valve it may cause it to leak water). I use this in combination with the msr hyperflow filter and gravity kit. The small opening fits the filter perfectly. This bag also allows me to back flush the filter. To keep the bladder clean, I will rinse with warm soapy water and hang it to dry. If mine ever springs a leak, I would not hesitate to purchase again.

    Rated 4 out of 5 by from Clear is good; opening too narrow Bought this to replace my Camelback.... Which still worked, but I couldn't see how clean it was. So, I love that it is see-through. I love that I don't have to re-thread the hose through my back pack every time, and it is very easy to connect the hose. Three big cons: the opening is too narrow to allow you to get your arm in to clean it, or to empty a tray of ice cubes in; and the easy click mechanism to the hose.... How can you possibly clean that? The water won't flow through it. I even tried pressing the mechanism as if attaching the hose - no go. Finally, the hose... I can't get it disconnected at both ends to run the Platypus cleaning brush that I bought with it! Two minor cons: the flow rate on the platypus is much slower than the Camelback; and it's a bit long to fill in the kitchen sink. If they made it shorter and wider (and wider opening) that would fix most of what is wrong with it. Still leaves cleaning the hose and connector as a problem though. I would recommend to a friend with reservations... Still better overall, than the Camelback, simply because I can see through it.

    Rated 3 out of 5 by from Still on the fence I was all jazzed about this hydration pack. Finally something made in USA for the outdoor enthusiast. I rinsed it out LOTS before use and still got a nasty plastic taste. My MSR bladder was good righ out of the box. Made of different material I suppose is the reason. I'm gonna try baking soda and see if it works to take that out. The bite valve didn't seem like it worked right but maybe it's because I never used one before. All in all I think it's a quality product at a decent price. And as I said, Made in USA. My first impression has been less than favorable. Gonna give it a chance though and if anything changes I will update.

    Rated 5 out of 5 by from Perfect! Never had a problem with it and it fits the hydration pocket in my Granite Gear Blaze A.C. 60 Ki Pack perfectly!

    Rated 4 out of 5 by from Works great, but rinse before using. The Platypus works really well for the price, and 3 liters is the perfect volume for most day trips. The only downside I've experienced is that the first drink of water tastes awful, a very strong chemical taste. This was after I had already rinsed out the bladder when I first purchased it. At first I thought I had gotten insect repellant on the tube, but my fiancee experienced the same taste when she took her first drink. What's odd is that the taste goes away after a few drinks, but I had the same problem again when I used it a couple weeks later. I expect that as I continue to use it this issue will go away...

    Rated 5 out of 5 by from simple and works well I gave my Camelbak bladder to my son and bought this 3-L Platypus, and I've been very happy with it. It's light and simple. I like that it only has one opening, so there's only one end it can leak from -- which it has never done. I've used it cycling, backpacking, and on day hikes including in desert terrain (the only time I've come close to emptying it). A few things practical things I do: at home and car camping I use a kitchen funnel to fill it. That works great. I don't carry a funnel backpacking, but it's something to consider. For transporting a full bladder in the car I put the bladder in the pack upside down (i.e. with the opening at the top) and set the pack upright. That minimizes the risk of leaks. We keep cold water in the refrigerator, and I've never felt the need to put ice in a hydration bladder. But if I wanted ice in this one I'd partially fill it and put it in the freezer overnight, then top it up before a trip. That's supposed to be OK. Wouldn't be able to repeat that on the road of course. I dry it by twirling it with the open end out to centrifuge as much water as possible out, then hanging it upside down with the sides opened apart. Putting the empty bag in the freezer to prevent mold as others suggest sounds like a good idea, too.

    Rated 5 out of 5 by from light and works well After debating back and forth about whether to get the one with the zipper or not, I decided to go with the most light weight one. If you want something that is light and keeps you hydrated, this is the bladder for you. I used it on a five day backpacking trip and it worked great. You do need to be careful not to put your backpack on top of the mouth piece because there is no shut off valve and it will cause the water to come out. I've kept it clean by rinsing it out and running vinegar water through it after a trip and although as others have stated, it doesn't dry out very well, I just hang it in the closet or toss it in the freezer. This bladder is a little harder to clean and I have to take it all the way out of my backpack to refill it but I am willing to put up with that because it is so light weight.
