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.

Practical, collapsible. But not the same material Platypus used for their bottles before .
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.

Great collapsible bottle for hiking
I bought this product for hiking Arizona and Utah in late July. It served as backup water for my family to supplement their reservoir backpacks. It had appropriate volume for longer hikes. This alone could serve 1-2 people for a 5-10 mile hike in that heat. As I mentioned, this was my backup water supply. I purchased because I thought his would be easier to transport versus rigid bottles. It was great for traveling, especially burying it in your luggage. It folds down quite small when not in use. Over 9 days of hiking, there was no noticeable taste to the water. I filled each morning, typically in the hotel gym water bottle filling machine. Durability was great for the trip. I used it hard with no failures. I assume it wouldn’t last as long as a rigid bottle, but the price makes it disposable if you do manage to damage 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
