Platypus Platy 2-Liter Ultralight Collapsible Backpacking Water Bottle

Works perfectly for usage. Does not leave any after taste I’m the water when stored in it all day.

We carry at least two of these on every backpacking trip, sometimes even three on longer trips. We hike in groups of three or four, and most every one has one in their pack. The uses for these are MANY, here are a few:- As a large "Dirty" reservoir for our Sawyer Squeeze or Sawyer Mini filters when we want filtered water "on the go". These thread directly onto the Sawyer filter threads, and fit perfectly. Having a 2 liter source for the dirty water means less dipping and transfer operations - and these are much more durable and user-friendly than the bottles Sawyer sells.- As a "Clean" reservoir for filtered water / storage when using our gravity filter in camp. We don't hang our clean water reservoir, we only hang the dirty, and use something like this to catch the clean water. Sometimes we fill two of these when we are setting up camp to have water for cooking , washing up, etc. What makes this a decent storage reservoir is that you can put a push/pull cap on it and be able to have controlled and measured pouring...- As a reserve reservoir for extra water when we might be away from water for a couple of days - when we know we may be away from water for a day or so, we fill our 3L bladders first, then fill this as a reserve in our pack. Note these are not as thick as a bladder, so store / carry in your pack with care, and keep it protected.I have been using one of these bottles for two years now, over multiple trips, and it is still in serviceable / working condition. Thus the durability of these bottles is not bad, and they last if you care them.If I had to think of any "Cons" for these bottles, or what I don't like about them:- It takes forever for them to dry after cleaning....the small opening and large volume means you have to find a nice place to store them for 2-3 days as they dry. I live in AZ, which is very dry, I can only imagine how long it would take to dry in a humid climate! I only clean these when we get home, I don't ever attempt drying them out on the trail.- The caps are not attached, and can get lost. This is one of the big reasons I started using the Evernew soft bottles - the Evernew bottles have the cap attached to the bottle!!- You have to carry a separate rubber band or shock cord to roll them up. Again, the Evernew bottle has a pigtail attached to facilitate rolling them up, where the Playtpus does not.Note that I recently have been alternating these bottles with the Evernew soft bottles - those are a decent alternative to these, and are priced in the same ballpark. I purchased these Platypus bottles for $9.99, and the Evernew 2L for the same amount.A couple of tips and tricks:- I carry two caps for these - one closure cap, and a push / pull cap. I do this for multiple reasons, the first one being in case I lose a cap. The Platy caps are not attached to the bottle like the Evernew, and could get lost. The second reason is that if I am storing the reservoir as a backup water source in my pack, I don't want the tall push / pull cap protruding and screw on the closure cap. On the flip side, if I am using it for water storage in camp, I use the push / pull cap for easy dispensing.- I got some 1/16th inch shock cord and made a permanent pigtail attached to the bottle so you can easily rollup up the bottle for compact storage. This is copying what the Evernew bottle did with theirs, and idea which I really liked. In fact, I have other Platy soft bottles, and retrofitted this pigtail on those too!! If you are wondering what I mean, see the picture. The Platy is on the left with the added pigtail, and the Evernew is on the right with the stock pigtail.Thanks for reading.

Wish it dried out easier but I leave it drying upside down in the dishes rack then turn it right side up for a few days and occasionally blow into it, to “puff it out” a little. Lying vs on its side also helps air flow and drying the inside out sooner. Rolls up easily. I recommend it.

I find some people's reviews of products really puzzling; like taking away a star because the threading on the opening doesn't fit other brand caps (why would you expect it to?) or that you can lose the cap easily because it's small (then don't lose it?) or that it [likely] can't survive a 30' drop like a nalgene could (it weighs 1/6 of what a nalegen does and is collapsible, why would you expect it to?)Here's what you need to know, for carrying a bit over 2L of water its amazingly light, only 1.3 ounces on my scale. It is also very rugged for a collapsible light weight water container.Take it for what it is; a very lightweight and fairly durable way to transport/hold a good amount (2L+) of water.As a side note, this will stand upright when filled with water, which is pretty nice.I personally carry this as a backup water carrier, or for when I make camp and want to filter a lot of water at once before bed so I don't have to in the morning. I only keep clean/purified water in it and when I need water from it I generally pour it into another container to use/drink. Because of the way I use it I'm not overly hung up with how it's difficult to clean because of the small opening, which I'd agree with. However because I again only put clean/purified water in there I just put a couple drops of bleach in and fill it up with water, let it sit over night and then pour it out. I really like this and carry it with me as a standard piece of gear, the pro's far outweigh the con's when used under appropriate expectations in my opinion.

I've bought and intensely used, Platypus collapsible water tanks and bottles for 20 years. I LOVE them. It is really difficult to find them in stores (or even Amazon) these days. I use them when hiking, biking, kayaking. I always carry two of them, one to hold unfiltered water, one to hold filtered water, that has also gone through my steri-pen.In the past 10 years, for some reason the 3-littre tanks seem to have been discontinued, and you can only find 2-littre ones, if you are lucky.However, what bothers me most, is that the material they are making Platypus tanks with now has changed.I'm not aware whether this change has occurred upon FDA recommendation, new legislation (that bans, for instance, BPA) or simply, a desire to lower production costs. But the new plastic is LESS flexible, and therefore, MORE BRITTLE. Yes, it is true O have bought more of these bottles in recent years than I did before, even when I am hiking less :(Before, you could collapse them in practically any direction, and they would hardly ever get damaged. Now, without even getting pierced, the material cracks, and they begin to leak without warning! Not good if you are carrying electronics in your backpack, or you are looking forward to a change of dry clothes after hiking in the rain for hours. Also, you do not want to lose water during a heatwave, far away from places where you can collect more, or buy other usable containers that are no-disposable or too heavy.These bottles continue to be the BEST way for me to transport clean water and water I have collected but not yet cleaned. They are GREAT. The best solution I have found that is lighter in weight than any other (I carry a 3/4-litre Nalgene from where I drink already clean water, aside from the 2 platypus tanks)I only wish the quality were what it used to be when I first discovered them, 20 years ago.
