The Platypus Platy 2-Liter Ultralight Collapsible Water Bottle is not just an outdoor essential, but an everyday, everyone, everywhere essential. Reusable, and refillable, it’s significantly lighter in weight than a hard water bottle of comparable volume and, when empty, collapses to take up a fraction of the space. While it’s designed for outdoor pursuits like camping, thru-hiking, and backpacking, it’s also perfect for travel, when space is at a premium, and is a safe option for the pool and beach, or anywhere that glass is impractical or hazardous. BPA-free, BPS-free, and phthalate-free, its food-grade polyethylene liner does not retain flavors, so it can hold water one day, and wine the next. When filled, the base expands so that the bottle stands upright; screw top keeps contents secure. The Platypus Platy 2-Liter Lightweight Foldable Water Bottle is compatible with all Platypus caps and drink tubes, and can be paired with a water filter, and the GravityWorks Water Filtration System. Bottle weighs just 1.3 ounces and measures 13.8 x 17.5 inches; total capacity of 2.1 liters (70 ounces). Made in the USA. Manufacturer’s limited lifetime warranty.
Taste-free construction is BPA-, BPS-, Phthalate-, and PVC-free, and does not have any residual taste or retain flavors
Ultralight material collapses and rolls up small enough to fit inside a pocket when empty, making it perfect for travel, camping, or backpacking
Can be used as the clean bag when paired with a Platypus GravityWorks, QuickDraw System, or other lightweight backpacking filter
Bottle has a stable base and stands up straight when full, while tapered design is easy to use
Measures 7.5 x 13.8 in (19 x 35 cm) and weighs an ultralight 1.3 oz (36 g)
Made in the USA

Platypus bottles so far does not dissapoint
Its as platypus describes, a soft collapsible plastic water bottle that weighs very little when empty, is durable to hold the volume of water, and comes with a screw cap. I have 3 other 1 L platypus bottles and they’ve held well for over 10 years. A reason for buying these is the quality of construction and the claim that plastic used are safe for drinking compared to no-name made in Cxxa you never know. Made in the USA helps. I don’t know why other had leak issues as reviewed, but that is possible with any plastic bottle or make. what I do is insure the bottle is always the last item packed and sits on top of a backpack of stuff [ also for easy access for drinking] to avoid squeezing the bottle and adding more strain that just the weight of liquid. its very easy to clean, has been leak proof for 1 week filled with 2L of water, it fits snug when empty and very easy to use. would buy again.

a very lightweight and fairly durable way to transport/hold water
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.

Water without the bulk.
Great construction and no leakage. It was the perfect water bladder for a hiking trip to Montana. It fit perfectly in my backpack.

Perfect for hiking
My son got this for hiking. Works great! Fits nicely in backpack. Took one star off cause it’s hard to dry after washing.

An invaluable tool in our backpacking arsenal – strikes the right balance of lightweight, volume and ease of use!
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.

Platypus has it figured out.
I have so many of these. They don’t leak, or tear. I still have one from like 8 years ago traveling light to the Boundary Waters. I mean, who wants to portage a glass handle of whiskey? No one.These lighten the load. And allow you to bring booze into a game with seamless effort. Well done all around. A little spendy for what it is, but the product is totally worth it.

This is an awesome product. When packing away it’s advisable to roll it up or lay it flat rather than fold it. The piece delivered to me was brand new and came in its original ‘Made in USA’ packaging. It’s made up of extremely good material and has no odor to it at all. Thanks Amazon for a great product and prompt delivery.

I like that it is 2 litres, enough for a full day hiking. And at the end of the day, it is foldable.

This is just perfect. I don’t use camelback anymore because you don’t see the amount of water remaining.When using this in my system, it’s easy to store (doesn’t take any place), and can be easily filled. Transparent, you’ll see if the water’s dirty.Fits most filter (ex : Sawyer, LifeStraw). Doesn’t leave a taste. Good quality. Only good thing about it! Never leaked for me !Would recommend ! Good price at 20-25 CAD$.XxX – Pete – XxX
