Platypus SoftBottle Collapsible Backpacking Water Bottle with Closure Cap

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.

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!

We bought two of these for airline travel and also for hiking and touring. They worked out very well thanks to a good design and durable construction. When empty, they weigh practically nothing and are super thin. When full, they hold a liter and can stand upright on a flat surface. We experienced no leaks from the bottle or the cap. We like the "closure cap," which is a screw-top cap, because it was very secure and leak proof. We had no issues putting full bottles inside our personal carry bags or backpacks. (Ours did come with caps.) The only negative we found is that there is no really good way to dry them out for storage. Even when we propped open the bag to allow for airflow through the cap, and fully expanded the bag, it still took several days for the inside to fully dry. Storing the bag with moisture inside will lead to bacteria and/or mold growth. We're not blaming the manufacturer, as it seems that this is a problem inherent with any collapsible water bag-type bottle with only a single small opening. So just be careful to let the inside fully dry before putting the cap back on and storing the bottle.

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

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.

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.

We are always looking to travel light & efficient. We bought these for a three week trip to Japan. One down side is the cap isn't a flip type and has to be removed from the bottle in order to have a drink making it easy to lose. After washing out, the bottle flattens keeping the moisture inside and does not dry out completely. The positive is it does travel flat but with the negatives outlined, it just doesn't work for us.

I use these all the time for hiking and travel, especially backpacking. I recommend you buy 3 or 4, and bring all of them when you go. They're very lightweight, and you can fit several into your pocket when they're empty. For compact lightweight travel, I like to measure dry sports drink powder into an empty bladder, then add water when it becomes necessary and available. For lightweight wine portability, carefully squeeze out the air before closing, to minimize bruising. Also squeeze out air before air travel. Although new Platys have no flavor, they can pick up slight taste when used with strong flavored beverages. Connoisseurs will want to dedicate one Platy for things like red wine or mezcal. Handy nipple caps for drinking straight from the bladder are sold separately. But they often leak during air travel, especially if you forget to bleed out the air. It's hard to dry the inside thoroughly after washing. So to prevent mildew, I always rinse with a little vodka before long-term storage. This does not seem to affect the durability of my Platys. For use with water filtration systems, hoses, and fittings, check for compatibility with Platypus brand. Otherwise adaptors are available.

山小屋泊で1リットル用を2つ持っていきました。いろはすのペットボトルでもいいかなと思いましたが、全然違う！バックの中での収納がしやすい、使い終わったらたためるのが便利！アウトドアにも大活躍！ほんとっお気に入りです☆

Good bottle, light weight easy carry. Would be great if they did smaller sizes as well.

We saw some people using these while at a sports game, what a fantastic idea! We've used ours few times now and they are awesome, most stadiums etc. have water fountains and they just roll up and fit in your bag or pocket. No questions while going through security.......... perfect! Especially for the hot summer days.

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.
