PlatypusSoftBottle Collapsible Backpacking Water Bottle with Closure Cap

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!

I have carpal tunnel and joint problems so I try to seek out ergonomic products. What's the healthiest vessel to drink water out of was also a concern of mine because I drink about a gallon (3.75 L) of water per day. The answer to that is glass, and I was in the market for a glass water bottle initially, but came to the conclusion that glass is just inconvenient. Mason jar styles with handles are fairly durable, but they're damn heavy, and you also look like an obnoxious hipster carrying one around.Then there's the glass water bottles with neoprene sleeves, but they still break very easily, and are still too heavy and too small.I wanted a bottle that's close to 32 oz or 1L, and I'm so glad I stumbled across Platypus products! This review is getting long so I'll just list the pros and cons:PROS:-Most lightweight reusable water bottle EVER! Doesn't make my hand tired from drinking or carrying it.-BPA free, but still plastic, that's good enough for me because I'm not a paranoid little snowflake about everything (I mean come on people, "lighten up" (ha) a little) It's just the most practical, honestly.-Anti microbial lining!!!! I didn't eve realize this until later, but had been noticing the water never got that nasty stale water bottle taste, even if forgotten for a few days.-Perfect for airports. Chug all your water before security, tuck it neatly in your bag, fill it up after security.-Easy to clean.-Seems quite durable as long as you don't puncture it with something sharp or something. You can fill it with water and throw it in a backpack and it never leaks.CONS:-Small mouth opening makes it annoying to fill up with a Brita pitcher; you have to be patient.-I'm scared I'm going to lose the cap and then I'll be screwed as far as portability goes-Sometimes slightly awkward to drink out of, might look a little funny.That's it! The pros far outweigh the cons! Get this bottle now!

I really want to give these Platypus water bottles 5 stars, but they need to solve the problem of the unattached cap. We've been using these bottles for a few months now, and they're great on the trail. They're very easy to hold and drink out of, and I really appreciate a collapsible water bottle that doesn't require you to suck or bite to get the water through the cap. But it's too easy to lose the cap. And they don't sell replacements. I had to go through my refrigerator trying every cap. A Hoisin sauce bottle cap worked best. Great bottle, please please add a strap to attach the cap!

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.

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

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.

I bought the 1-liter Platypus collapsible bottle for my vacation, and it met my expectations.The bottle is incredibly lightweight and collapses down to a compact size, making it easy to fit in my backpack without taking up much space. The only negative, and it’s a minor one, is drying it out between uses. It takes a couple of days to completely dry.
