The Platypus SoftBottle Water Bottle with Push-Pull Cap 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 taste like plastic and 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; Included Push-Pull Cap conveniently dispenses contents without removing the cap. The Platypus Ultralight Collapsible SoftBottle is compatible with all Platypus caps and drink tubes. Available in two sizes: 1.0-Liter size weighs just 1.2 ounces, and measures 13 x 6 inches, 0.5-Liter size weighs just 0.8 ounces, and measures 12 x 5 inches. Made in the USA.
Flattens and rolls up when empty, making it highly packable and saves space in travel bags, backpacks, and purses.
Versatile opening is compatible with any threaded Platypus lid, multiple water filters, and drink tube kits to convert the bottle into a reservoir
Bottle narrows at the middle to make it easy and comfortable to hold
Materials are taste-free, BPA-free, BPS-free, and phthalate-free
1 Liter capacity weighs just 1.2 oz, perfect for ultralight backpacking and camping
Size: 6 x 13 in (15 x 33 cm). Made in the USA

Great bottle for hiking & backpacking
This is a great bottle for hiking & backpacking. Love that it’s collapsible which makes it very convenient and functional. No smells or taste in water. Quality is excellent; did not burst when dropped on hard ground. Screw-on lid is nice and does not leak. Only recommendation would be to have the lid attached so that it could not be lost, but that is a very small matter, especially since everything else about it is great. Highly recommend.

Perfect travel hydration solution
This upgraded my travel experience more than items I’ve spent 5X as much on.Unlike a structured water bottle, this travels compact and flat, and takes up almost zero luggage space. This is so much better than metal in your luggage or a bottle on a carabiner. TSA also has zero interest in a flat plastic bladder, so it’s not at all something you need to keep in mind at security.Once you’re at your destination, it fills up easily because the neck can bend. There are faucets that would have been impossible to use with other containers that were no problem for my Platypus. Also, the bottle seals completely and weighs barely more than the water within, so it can do things like fit sideways on top of cans in a mini-bar (especially useful for hotel rooms where a stocked mini-bar is the only fridge).It travels well, fills and holds water well (including standing upright when expanded), and is economically priced. I drink enough water that I bought a second Platypus so one can cool while I drink the other. Highly recommended!

Extremely Light, Nearly Impenetrable and Very Packable – But Easily Made Useless
I have been a consumer of Platypus products for many years and have used them as they’ve evolved from thick plastic to this space age light polyethylene plastic. I have never had a problem with the quality of the bottle. I have never had a leak or had a bottle damaged by regular use. They fold up into small bundles for traveling and make excellent everyday reusable water bottles. This newer style feels fragile when you receive it but is as tough and reliable as any Platypus bottle I’ve ever used while being much lighter.My only issue with the Platypus is the cap. Unfortunately I have lost more caps than I care to admit. If you lose the cap and can’t replace it, especially when you are hiking or away from water sources the bottle becomes nearly useless. I always carry spares from older bottles and the cap is a relatively standard size so you can usually find some kind of replacement, so it hasn’t been a huge problem yet. If I had any suggestion for improving the design of these bottles it would be to include a cap which can be attached to the bottle like a gas cap is tethered to a car.Even with this issue, I can’t imagine not using Platypus bottles when backpacking or traveling. They are a great value for a great product.

Good product
It is compact and carries lots of water. The only concern I have is that it’s not easy to wash and throughly dry. But it was helpful in my trip.

Convenient and Sturdy
We took two of these hiking to refill our water bottles. They held up well in our backpacks. The plastic is thick and the caps seal fully, without leaking. They are very light and conveniently flatten when empty so there’s less to carry back. It was great to not have to ration water so much on the longer hikes/hotter days.

Must buy!
Recently purchased these for our trip to Europe for my sons and me. These were perfect! They folded up to fit into your pocket or backpack and were easy to fill. Holds 32 oz, which was great for the hot weather and long walks. They did not leak and were easy to fill, wash, and use. So glad I purchased these. People asked us about them when they saw how much water they held and how compact the bottles are. Great product

Perfect for traveling!
This is the best water bottle! I don’t like to lug water and this is perfect to stow while traveling and fill up at the hotel water filtration station.

Fantastic convenience, easy use, questionable durability.
I’ve been through four of these bottles (0.5 or 1L size) – two for me, two for my partner – and I’m very torn about whether to get another one.Pros:1) Flexible! – it can squeeze down to take up less space as you drink more, fit flat in a pocket or backpack, fold for smaller pockets… the convenience is unbelievable.2) Reusable – I can’t stand generating plastic trash for landfill or even recycling, so any reusable waterbottle is great.3) Versatile – because of the flexible design, you can even use the larger ones as a head-cushion or as padding when full!4) Cool – the design I most recently had (mountains) looks really good and often elicits questions about the bottle, which is a good chance to evangelise about the importance of reusable water-bottles.Not-Cons:1) NOT hard to drink from – despite what other reviews say – you just need to know how. The trick is simple. Just grasp it about the middle (where the ‘waist’ is), holding it PERPENDICULAR to your face (i.e. flat sides facing left and right, not front/back or up/down) as you raise it to your mouth to drink. Easy – no flopping, no spilling, perfect control for one-handed drinking!2) NOT hard to stand – just keep the right amount of air in the bottle and it stands up just fine whether with little or lots of water inside.3) NOT hard to clean – maybe it’s because I use it while eating all the time, but the mouth/cap do get a bit grimy pretty quick. It’s a little tricky to clean the cap, takes some effort with a bottle-brush. But cleaning the inside of the bottle just requires shaking/rinsing with a bit of detergent.I’ve loved using the bottle, so with all these great advantages, why am I hesitating about getting yet another one?Con:1) Durability – just one big problem here. Not the seams, those have held up fine – but the plastic itself, where it folds most frequently, has eventually cracked within 1-2 years each time, causing leaks. In two cases it was near the top, where the spout inserts into the bottle; for the other two it was the bottom surface, which folds and creases every time you flatten/refill the bottle. You’ll see the stress points appear after some use, and eventually, they always give way. This hasn’t been unusually heavy use, mind you – I rarely actually fold or roll up the bottle, just fill/empty/refill, flattening and reopening it each time.This durability problem is a really major issue – it’s happened to all four that I’ve had. The point of reusable bottles is to NOT need to throw them away, and lasting 1-2 years just isn’t quite long enough to justify one (compared to a longer-lasting bottle). So much as I love using my Platypus bottles, I’m not sure I’ll get another.

These bottles are great. Not much to say it’s as advertised a 500ml bottle that collapses down quite small. Doesn’t leak and holds up well even to accidental freezing. I use it for snowboarding, golfing, or any other time you don’t want to carry a clumsy empty water bottle after you drink it.

Légère, pas de goût de plastique, en y faisant attention dure 3 ou 4 ans d’utilisation intensive avant de finir par fuir.

Great for flat packing and travel, just roll it up when empty into as small a space as you want and then fill it up when you get through security, the cap has a tight seal and has yet to leak through countless days being squashed in a rucksack whilst being pressure by a lab coat and folders and the quality is what you would expect of a platypus product, I will get another platypus bottle in the future should this one break due to my own negligence.
